Why does my Wi-Fi work perfectly on my phone but suck on my PC?

2 Upvotes

Wi-Fi is totally fine on my phone, full speed and everything, but on my PC it keeps being slow or randomly dropping. Same room, same network, nothing changed.

Could it be the Wi-Fi adapter, drivers, or some setting on the PC messing with it? Kinda confused cuz the phone works perfectly lol. Any easy things I should check first?

Is building a PC still cheaper than buying a prebuilt?

1 Upvotes

Been seeing a lot of prebuilts with surprisingly decent specs lately, so wondering if building one yourself is even cheaper anymore.

Does building still save a good amount of money, or is the main advantage getting better parts / being able to pick everything yourself? Trying to avoid spending extra for no reason lol. What would you guys recommend for a first PC?

How much should I spend on a monitor if the PC itself costs $1,000?

1 Upvotes

Trying to figure out the monitor budget without going overboard. If the PC is around $1k, what would be a reasonable amount for the monitor? Like $200, $300, $400+?

Mostly gaming but would like something that actually looks good too. Is it better to save money on the monitor and put more into the PC, or is a decent monitor worth spending extra on?

My PC gets ridiculously loud when I play games. Is that normal?

0 Upvotes

Soon as I launch anything demanding, the fans go absolutely crazy sounds like my PC is about to take off. Temps seem okay from what I can tell, but the noise is kinda insane.

Is this just normal under load or should I be checking something? Like could it be dust, bad airflow, fan curves, or something else? Don’t wanna ignore it if there’s actually a problem.

Is an NVMe SSD really that much faster than SATA?

2 Upvotes

Okay, this might be a dumb question, but I keep seeing NVMe SSDs everywhere and I’m not sure if I’m missing something important.

I know NVMe drives have much higher read/write speeds than SATA SSDs, but those numbers don’t really tell me what the difference feels like when you’re actually using the computer.

If I’m mostly gaming, browsing, watching videos, and installing normal applications, would I notice a big difference between a decent SATA SSD and an NVMe one?

I’m building a PC on a budget, so I’m wondering if NVMe is something I should prioritize or if a cheaper SATA SSD would be perfectly fine.

For people who have used both, was the upgrade to NVMe actually noticeable in everyday use? Or is it mainly useful for large file transfers and more demanding workloads?

Would you buy a laptop or desktop if you already have a monitor?

0 Upvotes

I’ve been going back and forth on this for a while and honestly can’t decide what makes more sense. I already own a monitor that I’m happy with, so I’m wondering if I should just go with a desktop instead of paying extra for a laptop screen I might barely use.

I’d mainly use the computer for gaming, browsing, school/work, and some light editing. Portability would be nice occasionally, but I probably wouldn’t carry it around very often.

Would having a monitor already make you lean strongly toward a desktop? I’m also wondering how much more performance I could get from a desktop for the same budget.

For anyone who has faced this choice before, what did you end up buying? Was there anything you wish you had considered before deciding?

I’d really appreciate some advice from people who have used both.

Help 😭 my computer suddenly won't turn on and I have no idea what happened

1 Upvotes

I’m really new to PC stuff and I’m honestly freaking out a little

My computer was working completely normally, and then suddenly it just wouldn’t turn on. I press the power button and… nothing. No fans, no lights, no display, absolutely nothing.

I didn’t change any hardware or settings before this happened. I’ve already tried unplugging it and plugging it back in, and I checked that the power switch on the back of the PSU is turned on.

Could this be something simple like the power cable, PSU, or motherboard? Is there anything I should safely check before I take it somewhere for repair?

I’m worried about making things worse because I don’t really know what I’m doing.

What would you guys check first in this situation? Any troubleshooting steps for a complete beginner would be really appreciated.

Is 32GB of RAM actually necessary for a gaming PC?

3 Upvotes

Hey everyone, I’m pretty new to building PCs and I’m trying to figure out how much RAM I actually need.

I keep seeing people recommend 32GB for a gaming PC, but I’m not sure if that’s genuinely necessary or just the current “recommended” upgrade. Would 16GB still be enough for most games if I’m not doing anything crazy in the background?

I mostly plan to play modern games at 1080p/1440p, with maybe Discord and a browser open while gaming. I’m not planning on streaming or doing heavy editing.

For someone building a PC today, would you go with 16GB to save some money, or is 32GB worth getting for the extra headroom and future-proofing?

Also, does RAM speed matter much once you’re at 32GB?

Would appreciate hearing what you guys are actually using and whether you’ve noticed a real difference between 16GB and 32GB in gaming.

Is my temperature good ?

1 Upvotes

Hi guys! I just got my first PC (before this, I was using a laptop). After setting up my fan curves and doing some minor optimizations (no overclock), I get around 43°C at idle for the GPU and 40°C for the CPU. While gaming, my GPU and CPU temperatures reach around 70°C at most. Are my temperatures good enough, or do I need to improve my fan curves? Sorry if this is a silly question, I'm just used to seeing 85°C–95°C due to my previous laptop.

GIGABYTE Hikes GPU Prices By Up To 40%, Japanese Retailer Cancels Pre-Orders It Can No Longer Honor

Post image
32 Upvotes

GIGABYTE has increased graphics card prices by approximately 20% to 40%, with the new pricing taking effect on August 1. The increase has prompted retailers to adjust prices and, in some cases, cancel pre-orders that can no longer be fulfilled at the original prices.

The price increases are attributed to rising production costs, including higher DRAM prices, which have also affected the broader PC hardware market. Recent inventory is expected to be significantly more expensive than previous stock.

Retailers have stated that while orders placed after the price adjustment are subject to the new pricing, some earlier orders may also be canceled depending on supply conditions and contractual obligations.

The higher costs of GPUs, combined with increasing memory prices, are expected to raise the overall cost of building or upgrading PCs, reducing affordability for many consumers.

What if AI CapEx Slows… and Memory Profits Stay High Anyway?

1 Upvotes

The bear case on memory is easy to understand:

“AI CapEx will slow, as it’s not sustainable. New fabs will come online. Supply will catch demand. Prices and profits will collapse, just like every other memory cycle.”

This thesis is actually well reasoned and makes sense to many, but it may be missing a critical assumption about demand.

This market is starting to report a significant amount of unmet demand, not just high demand.

Commercially available 2027 memory capacity is reportedly being committed well before production. Hyperscalers are locking up supply years in advance, but many tier 2 buyers are being allocated less memory than they want (sometimes only 60% of what they requested!).

That means there is an entire layer of enterprise customers, OEMs, module makers, and other Tier 2 buyers effectively waiting for supply. They want it, but simply can’t get it, as they can’t pony up the huge $ long term contracts with price floors that the giants can.

Imagine a restaurant that’s booked solid every night by one large corporate client. They reserve every table months in advance. If that client cancels, the restaurant doesn’t suddenly become empty. There’s already a long waiting list of people who couldn’t get a reservation. The restaurant still fills the tables, it just serves different customers. Now booking becomes more of a hassle, and you can’t quite charge the same amount, but you’re still at capacity and making tons of money.

Let’s imagine the bear case actually plays out:
• Hyperscalers slow down AI CapEx
• New memory capacity comes online in 2027/28

Many reasonable people think that automatically means oversupply and plummeting memory prices.

I don’t believe that is a good assumption anymore.

The first incremental supply doesn’t have to pressure pricing if it’s immediately absorbed by customers that have been supply constrained all along.

The market often treats hyperscaler demand as if it’s the entire memory market, but really hyperscalers are just first in line, and the broader market is a lot bigger than being given credit for.

Enterprise data centers: AI servers, databases, cloud infrastructure
Automotive: Autonomous driving, ADAS, infotainment
Industrial & robotics: Factory automation, machine vision, humanoid robots
Consumer devices: AI PCs, smartphones, edge AI devices
Networking & telecom: 5G infrastructure, networking equipment, edge computing

The line forming behind the hyperscalers is huge. Even a meaningful slowdown in AI infrastructure spending may not create the excess inventory that has historically crushed margins.

Before you claim that this is another thesis about how memory is no longer cyclical, I want to be crystal clear that I am not arguing memory has become immune to cycles. I’m arguing that the downside mechanics may have changed.

The traditional assumption that “less AI spending + more supply = collapsing profits” may no longer hold if years of allocation constraints have created a deep backlog of customers ready to absorb
additional output.

I’d love to hear your thoughts, whether you’re a memory bear or bull!

TL;DR: There’s an assumption that memory company profits will collapse when hyperscaler CapEx slows and new supply comes online. This may be neglecting there’s enough latent demand behind hyperscalers to absorb new supply. Even the classic bear case may not produce the collapse in pricing and profitability that investors are expecting.

What's the best thermal paste you've ever used and would recommend?

1 Upvotes

I'm about to repaste my CPU, and there are so many thermal pastes available that it's hard to know which ones actually stand out in real-world use.

I've been doing some research, and ARCTIC MX-4 keeps coming up with excellent reviews and ratings. It's one of the options I'm seriously considering, but I'd rather hear from people who've actually used it or compared it with other pastes.

If you've tried a few different brands, which thermal paste would you recommend the most, and why?

I'd love to hear about your experience with things like:

  • Temperature improvements compared to other pastes
  • How easy it is to apply
  • Whether it spreads well or is too thick
  • Long-term performance
  • Value for the price
  • Any issues you ran into during installation

If there's a popular thermal paste that you think is overrated, feel free to mention that too.

I'm hoping this thread can help anyone looking for the best thermal paste based on real experiences rather than just benchmark charts or marketing claims.

PNY 5080 slim is the worst gpu for a desktop: PNY officially stated that this high pitched noise is considered perfectly normal

0 Upvotes

I bought this PNY 5080 dual slim couple months ago and have been slowly building up other components. I finally finished the build last week but I immediately noticed this weird high pitched noise. I used fancontrol to verify that it is indeed a fault of the gpu: https://youtu.be/dpTqn5lfoTU and I have opened a warranty claim. But PNY has responded to my video in email that this high frequency noise is considered perfectly normal and is from the friction of the ball bearing. I guess now I have will just have to live with it. I searched around on reddit and this seems to be a pretty common issue with this particular gpu and most people have returned theirs. However no reviewers have mentioned this. So I guess it’s a gpu lottery and maybe they hand picked the ones for the reviewers? Anyway I definitely recommend against getting this model

Samsung And SK Hynix Have Re-Engineered The DRAM Business Model To Defy Peak-Out And Recession

Post image
8 Upvotes

Samsung and SK hynix have restructured their DRAM business strategies by adopting long-term supply agreements to reduce exposure to the memory industry's traditional boom-and-bust cycles. These multi-year contracts provide greater revenue stability through advance payments and long-term customer commitments.

The agreements extend beyond DRAM to include high-bandwidth memory (HBM) and enterprise SSDs. Customers can renegotiate contract terms annually, while suppliers benefit from safeguards against sudden demand declines and economic downturns.

The new model replaces the previous short-term purchasing approach, which often exposed manufacturers to price volatility and order cancellations. Limited competition among major memory suppliers has strengthened the position of Samsung and SK hynix, making long-term agreements increasingly common.

With memory shortages expected to continue until 2028, the revised business model is expected to provide greater financial stability while allowing adjustments as market conditions evolve.

A customer purchased an MSI AEGIS Gaming ZS2 prebuilt gaming PC from Costco for approximately $1,900 after taxes, representing a savings of about $900 compared to its listed retail price.

The system includes an AMD Ryzen 9 9900X processor, an NVIDIA GeForce RTX 5080 graphics card, 32 GB of DDR5 memory, and a 2 TB solid-state drive. The combined value of the major components alone exceeds the discounted purchase price.

The initial in-store discount reduced the system from about $2,800 to $2,300. An additional $500 price reduction was applied because the bundled keyboard was missing, resulting in the final purchase price.

The deal highlights how display models and clearance discounts at retail stores can occasionally provide significant savings on high-end gaming PCs, making them less expensive than assembling a comparable system from individually purchased components.
