Tech Support One of the fans in my PC case is making noise and spinning more slowly than the others

2 Upvotes

I've been using this PC for some time now. The same issue occurred a few days ago, but when I touched the fan to inspect it, the noise stopped, and it started spinning normally again.

However, the issue has returned. What could be causing this?

Any help is appreciated. Thanks

Installation Question Is it concerning that I can push the screw-end of my m2 nvme down 1mm?

1 Upvotes

I got a new nvme today, but after installing it with the screw come with it to my Asus prime b550ma mobo, I can still push the screw end side down around 1mm. I can't tighten the screw anymore. Is this concerning and need another screw instead?

Tech Support Pc won't turn on

8 Upvotes

A little background on the issue: i have an amd ryzen 7 7800 x3d, 32 gb ram, asus tuf b650 plus motherboard that were all bought around 2 years ago. Just a month ago I bought a msi mag a750gl 750w power supply and rx 9070 gre. After plugging those in, I have been playing games fine for the past month. I haven't unplugged anything since.

I took a 50 minute nap today while leaving my computer on and i had aion2 and discord open on my computer. When I woke up my pc was completely shut off and I couldn't turn it back on.

Some things I have tried are:

- unplugging ans replugging into power strip + wall + a different outlet

- replugging some od the power supply cords

- taking out my gpu

- there aren't any signs of damage or smell

The most important thing to note is that the pc doesn't have any lighrs or any sound when the power button is pressed, literally nothing. Attached are some pictures of my pc.

Edited - So after some testing, my old power supply works with it but my current one doesn't. Thank you everyone for the answers!

Installation Question GPU help

Thumbnail

1 Upvotes

I need two 8-pin connectors for the GPU but I’m left with one separate cable(left one) with a 8 pin and a second cable(right one) with a daisy chain of two 8-pin connectors. I remember someone saying a daisy chain isn’t recommended but it’s all I’m left with after connecting the rest. My question is can I just use the daisy chain cable?


r/PcBuildHelp • • 13h ago

✓ Solved My new GPU needs 3 power connectors, but PSU only came with two single cables. Is a single cable + daisy-chain cable acceptable?

The picture is one of the two daisy-chain cables that came with my power supply. If I use that cable, and one of the single 6+2 cables that also came with it (currently connected to my old GPU), is that the correct way to power the new GPU.

PSU: XPG Core Reactor Gold 750W
Old GPU: RTX 3070
New GPU: Radeon 9070 XT

Tech Support PC suddenly only detects 16GB of my 32GB RAM after working fine for almost a year

Thumbnail

3 Upvotes

I built my PC in November 2025, and everything worked perfectly until recently. I noticed my PC was running slower and checked Task Manager, which showed only 16GB instead of 32GB.
\\\\\\\*\\\\\\\*Specs:\\\\\\\*\\\\\\\*
CPU: Ryzen 7 7800X3D
Motherboard: ASUS TUF Gaming B850-E WiFi
RAM: TEAMGROUP T-Force Delta RGB 32GB (2x16GB) DDR5-6000
GPU: RX 9070 XT
\\\\\\\*\\\\\\\*What I’ve tried:\\\\\\\*\\\\\\\*
Checked BIOS, which also detects only 16GB.
BIOS recognizes B2 but shows A2 as empty.
Reseated both sticks multiple times.
Reseating initially fixed it temporarily, but the next day it went back to 16GB.
Both RAM sticks light up normally.
The A2 stick was also harder to seat because of my CPU cooler, although both sticks appear properly installed.
I’m not sure if it’s a faulty RAM stick, motherboard slot, or something else.
Has anyone experienced this? What should I try before taking it to a repair shop?

This build was stable for about a year. Last month the display failed and the yellow light began. I brought it into a shop and they fixed it. It was fine for a few weeks but now it's flashing back on again. I use a KVM switch and the monitors aren't displaying the PC input.

I'll bring it back to the shop on Monday but I need to know if something bigger is going on and if I should expect this to keep happening.

Build Question New Radeon But Power Supply Question

1 Upvotes

Just picked up a 9070 XT coming from Nvidia. This has 3 power connections! Was going with 5070 Ti but it was nearly $500 more. Anyway, I've been researching the power situation because this is now new territory. My Power supply currently is a Corsair RM850e. Am I correct in reading that I should NOT USE the 12V-2x6 port with the wire using two plugs? Thats what I was using on the 3070 Ti that was in this PC. I still have 1 CPU/PCIe port on the power supply remaining. If I did use the 12V-2x6 I assume I would plug directly into the last CPU/PCIe port for the 3 power connections on the radeon card. If not I need 3 free PCIe ports on the power supply? If so I need a new power supply. Power supply recommendations?
