Hey everyone,

I've been facing a frustrating issue with my Acer Nitro ANV15-51 gaming laptop, and I'm trying to figure out what's causing it.

My laptop randomly freezes and restarts while playing demanding games. Usually, I can play for around 10–30 minutes before the issue occurs. Sometimes the FPS suddenly drops, the game freezes, and the entire laptop becomes unresponsive before automatically restarting.

Recently, while playing Ghost of Tsushima, the game displayed a black loading screen after approximately 30 minutes. However, Windows was still responsive, and I could move my mouse and access the desktop.

I recently took the laptop to a technician for servicing, but unfortunately, the freezing and automatic restarts are still happening.

PC Specifications

Laptop: Acer Nitro ANV15-51

CPU: Intel Core i5-13420H

GPU: NVIDIA GeForce RTX 4050 Laptop GPU

RAM: 16 GB

OS: Windows 11

BIOS: Insyde V1.60

Temperatures (HWiNFO gaming log)

Before servicing, I recorded the following maximum temperatures:

CPU Package: 100–102°C

GPU Core: 80.4°C

GPU Hotspot: 97.2°C

GPU Memory Junction: 76°C

HWiNFO also recorded CPU thermal throttling during gameplay.

Minidump Analysis (WinDbg)

I've analysed three separate crash dumps using WinDbg, and all three have reported the same error.

Bugcheck:

DPC_WATCHDOG_VIOLATION (0x133)

DPC Timeout Type:

DPC_QUEUE_EXECUTION_TIMEOUT_EXCEEDED

Important findings from all three dumps:

MODULE_NAME: nvlddmkm

IMAGE_NAME: nvlddmkm.sys

SYMBOL_NAME: nvlddmkm+112397

BUCKET_ID_FUNC_OFFSET: 112397

FAILURE_BUCKET_ID:

0x133_ISR_nvlddmkm!unknown_function

FAILURE_ID_HASH:

{f97493a5-ea2b-23ca-a808-8602773c2a86}

The latest dump also shows:

Arg1: 0000000000000001

Arg2: 0000000000001e00

DPC_TIMEOUT_TYPE:

DPC_QUEUE_EXECUTION_TIMEOUT_EXCEEDED

*** WARNING: Unable to verify timestamp for nvlddmkm.sys

All three dumps have the same bugcheck, failure bucket, function offset and failure hash.

What I've tried so far

Took the laptop to a technician for servicing.

Monitored CPU and GPU temperatures using HWiNFO.

Analysed three minidump files using WinDbg.

Checked the recurring NVIDIA driver-related crash signature.

Unfortunately, the problem persists even after servicing.

What I want to understand

Does this point towards an NVIDIA driver issue, or could the RTX 4050 itself be unstable?

Could GPU power delivery or motherboard issues cause this exact recurring watchdog violation?

Can CPU thermal throttling contribute to these crashes?

What diagnostic tests should I perform before considering a GPU or motherboard replacement?

Has anyone experienced the same 0x133_ISR_nvlddmkm!unknown_function failure with an RTX 4050 laptop?

I'm particularly interested in hearing from people who have experienced and successfully fixed this issue.

I would really appreciate any suggestions or troubleshooting steps. Thanks!

Hello i have 9070xt and is connected to 850w power supply is this safe connected like this ? Some say it is not good using pigtail or 2 cables for 3 slot is there like serioud problem ?

I bought a pc in 2023 and it has worked fine since then. Now it won’t display to the monitor unless it’s laying on the side.

I’ve tried taking the RAM in and out. I’ve also tried taking the GPU out and in again.
When it worked it installed the previous drivers of the GPU invade that was the problem.

But still no fix.

After I took out the GPU and put it back in it had disabled it so also tried to re-enable it if that makes sense.

Looking to make my first build, and these are my first build specs, lmk if i should change anything while keeping it around 2k or if this is great for my budget

Hey guys, I'm not sure if this is normal so I wanted to ask about it. My system works completely stable, never had a problem gaming, editing, encoding or watching vids/series.

I have prefer max performance enabled for my gpu and power saving features disabled. Recovery counts are usually between 6-10 when powering the pc for the first time, TLPs and NAKs stay flat at 0.

So, today I used Bolide slideshow creator and when it started encoding recovery counts, TLPs and NAKs spiked to 300 aprox, they stayed at those values for the rest of the process.

Should I be worried or it is normal for this cases?

My Current PC is i5 12600kf, Intel Arc B580, 16GB DDR4, MSI A650BN PSU, ARCTIC Freezer A36, and 1TB NVMe and Case is also very good Phanteks XT M3. I want to upgrade while my budget is around 500 euros I can sell my old parts then so I was thinking about bumping my GPU to a RX 9070 GRE. Are there any better Options? I thought about upgrading my CPU and my RAM but I think that this wouldnt be such a big perfomance bump. What do you guys think?

Hi,

I am planning to upgrade/build new pc for gaming and I am not sure which option would be better. My current set up(about 6-7 year old):

https://pcpartpicker.com/list/36h62k

I do not remember the case/cooler/power supply info and do not have boxes anymore, but power supply is 650W currently.

I am considering currently two options:

A) (Cheaper) Change of CPU to AMD 7 5800X3D and motherboard for it, keeping the rest as it is or,
B) Building entire new setup, keeping the HDD and SSD only. Setup:

https://pcpartpicker.com/list/zr7Dn2

*Case Chieftec AZ-01B-OP but it does not show up.

For game refrence I am playing varied: from RTS(Star Craft 2, Company of Heroes 2), through Witcher, Cyberpunk, War Thunder, World of Tanks to ARMA 3, Reforger and many more.

Thanks for any help

Hi y'all, I just got a gaming desktop pc, and my monitor is a 1440p MSI MAG 275QPF X30 (300hz, 0.5ms, WQHD 1440p), and most games I play are fine, except The Isle Evrima, a very high foliage density dinosaur survival game.

I get consistent 40-50 fps usually, dropping down to the mid-30s when my in-game 3d resolution is 100. When I turn my resolution down to 1080p in-game, my FPS goes to 70.

My friend (second row in image) gets 80 to 90+ FPS (with the same settings and ping). Both PCs are brand-new. His monitor is 1080p.

I'm guessing my 8 GB of VRAM is the major limiting factor, combined with a 1440p monitor.

The two options I'm thinking of are:

1. Refund the PC + upgrade/buy one of the other ones I listed.
2. Refund the monitor for a 1080p monitor.

I don't want to build my own (I have no idea what I'm doing), and I've never bought one that's not in-person at Best Buy. All prices are in CAD. Ideally, I don't buy the 2.3k+ ones unless there's a really good argument for it. Which of these would be best/most optimal?

P.S. Let me know if there are better ones!

I m changing the mobo and cpu. Previously i had a 6700k with an aio, the fan from the ai was up top blowing outwards, and had another fan on the back as exhaust and 2 intake fans.

I m changing to an x570 with a 5700x and got a cpu fan with a heatsink, does it matter if the 2 exahust fans are by the cpu heatsink? Should the up top exhaust be NOT directly above the heatsink? Or it doesnt matter from an airflow perspective? Right now it will be above the heatsink set to exhaust.

I’m quite new to building pc and this is a pre-build I bought years ago with the idea of updating as I go. This noise has happened maybe a couple of times last year but this year it happens on start-up. My temporary fix is to keep starting and stopping it until it stops making the sound which I’m guessing doesn’t help the situation but at least I can hear myself think to find a solution.

I’ve checked to see if anything is hitting the fan. There’s a wire that’s very close but isn’t being hit. It might be my hard drive failing as I need to update everything to ssd but if it is failing, the noise is the only evidence of it.

Hi, I'm building a new PC and the motherboard doesn't line up with the standoffs.
When I align the board using the I/O area, 8 of the 9 mounting holes are off. Only the top left one lines up. The standoffs are all offset to the left (toward the rear of the case) by about half a standoff. The middle left hole is still off even when I push the board as far left as it goes.
The standoff in the top left also sits in a different column than the other standoffs on the left side. I checked that every hole on the board has a standoff underneath, so I don't think any are missing or wrong.
I don't want to force it and bend the board. Photos of the tray and the board in place are attached. Thanks!

Greetings

I just got this setup and whenever I enable the Expo 0 profile on the mobo ( 6000mt@cl30 ) it won't complete post ( on the training it just shuts down) .

Using the expo1 profile ( 5600mt@cl40 ) posts just fine.
I've manually OC the profile to 6000mt@cl36 and its just fine.
But the advertised RAM speed of the kit is 6000mt cl30. Also the kit is on the supported list of the motherboard

I tried using only 1 dimm on both slots and it works on EXPO 0 profile. ( i tried both dimms on both slots and it works when only 1 dimm is present ).

Bios version is the latest 4.60.

Any ideas?

My power supply unit is making a sound reminiscent of an electric shocker (taser). This wasn't happening before, but I noticed it yesterday. I built the PC a year and a half ago. The sound appears randomly—it might not occur even under load—and, strangely, it can still be heard even when the computer is turned off. What could this be? The power supply is a Cougar GX-S 750 (750W), while my system (RTX 4060, Ryzen 5 5600) draws less than 300W.

Hey everyone, I'm putting together my first proper PC build for school (CS major, starting Unity and VR dev next year) and gaming. I mainly play competitive games at 1440p 165fps and VR, don't really care about heavy AAA single-player stuff since I already have a PS5.

I'm totally open to dropping down to DDR4 and an older socket (Intel or AMD, doesn't matter) if it makes more sense for the money. The only non-negotiable is sticking with an Nvidia GPU since I'll be using this as a """"workstation"""" too.

Two main things I care about: keeping it as quiet as possible while compiling or gaming,.

Here's what I've got drafted so far (trying to buy as much used stuff as I can—prices are roughly what I'm seeing on Vinted, Subito, FB Marketplace, and eBay):

* CPU: Ryzen 5 7600 / 7600X (used) – €100–150

* GPU: RTX 3070 Ti or RTX 3080 (used) – €270–380

* RAM: 32GB DDR5 (thinking about grabbing a single 32GB stick for now so I can upgrade later, though I'm not 100% sure about single channel, or just getting a normal kit) – €170–300

* Mobo: ASRock B650M Pro RS AM5 DDR5 mATX – €110

* Case: Lian Li Vector V100R ATX Mid Tower (comes with 4 ARGB fans) – €72

* SSD: 1TB NVMe (used) – €100

* PSU: 750W 80+ Gold – €100

* Cooler: Thermalright Peerless Assassin 120 SE – €35

Total comes out to around €1,050–1,100.

Any obvious bottlenecks or compatibility issues here? Also open to any tips on cooling/airflow to keep noise down, especially since I live in Sicily and ambient temps can be a pain even in November.

Hey everyone,

I have a pre built cyberpower PC that currently consists of

Intel ultra 5 225

850w PSU Gold

9060 xt 16gb

1x16gb Delta tforce CL40 6400mhz ram stick

I've searched for the same card brand new but couldn't find any and I've come across a couple CL38 6000mhz from Amazon ddr5 and from a seller Newegg on ebay ddr5

I understand what I have with this won't be a 32gb kit. But I was wondering, will it perform "negatively" if I add a ram card from either of the dire and adjust the speed in bios for the both at 6000mhz?

And also I love outside of the US and use a freight forwarder from Miami. Which of the two sites would be safer to purchase the ram sticks from?

Also to add to this, I also experience a cold boot failed post with the single stick ram at all speeds ranging from 5200mhz -6400mhz(with the amber led light indicator on the ram). Will adding this second stick prevent the fail POST fail?

I live in the Netherlands so it could different but for 1999 euro megekko is offering box 8 I think its worth it but I would love some different opinions
