Custom built desktop PC: My PC keeps crashing completely randomly.

Tue, 20 Jan 2026 12:42:03 -0700

My custom built desktop pc (parts list here) keeps randomly crashing. What happens is usually:

My monitor loses signal
all my peripherals stop working
The pc seemingly stays on for a few minutes (the rgb doesn't turn off)
The pc finally shuts down.
I've tried multiple things to fix this issue. I've reset my bios by removing the battery from the mobo, and I've reseated my gpu and ram. Somehing to note is that sometimes the pc emits an odd smell, like a burning smell. Can anyone help me fix this to get my pc working again?
(AMD Socket AM3 unrelated, i just picked that because the forum told me to select a device)

Custom built desktop PC: PC making weird buzzing noises

Fri, 21 Nov 2025 23:51:44 -0700

Hey everyone,

I’ve recently started having an issue with my PC where it makes a constant buzzing sound as soon as it starts up, and the noise does not stop as long as the PC is on. This wasn’t happening before — it started about a month ago, and I bought/built the PC back in May, so it’s still pretty new.

I’m not sure if it’s coil whine, a fan issue, PSU noise, or something vibrating. The buzzing is noticeable and definitely wasn’t there during the first few months.

Here are my full specs:

CPU: AMD Ryzen 7 9800X3D (4.7 / 5.2 GHz)
Motherboard: Gigabyte X870 AORUS ELITE WIFI7
GPU: ZOTAC GAMING GeForce RTX 5070 Ti SOLID SFF OC 16GB GDDR7
Case: CORSAIR 3500X ARGB Black
SSD: Samsung 990 EVO Plus NVMe
PSU: MSI MAG A850GL PCIe5
Cooler: Lian Li Hydroshift LCD 360R Black
RAM: Kingston Fury Beast 32GB DDR5 6000

Monitor: ASUS ROG Strix XG259CMS 24.5" 310Hz

I recorded a short video of the sound here:

Any advice would be appreciated

Custom built desktop PC: Why does my pc load games up so slow?

Tue, 07 Oct 2025 17:17:59 -0700

I have an older computer, it's about 4 years old now, and when I boot up games like Fortnite or even when loading up Discord, it drags. With Fortnite, it takes a long time to load up, and when I play with a friend, they will load into the match fine, but I won't load it until the bus kicks everyone out. I don't have a lot of things installed, so I know it's not something storage-related, and I've been keeping up with driver updates.

Hi I have an old computer

Today I turned it on and it worked fine for ten minutes until I opened YouTube on a browser and right about when it was ready to load the computer suddenly turned off.The pc wasn't turning on again.I changed the power supply and the pc turned on but the pc turned on when I pressed the power supply's button(Which is strange because It should turn on when I Press the power button on the case).The pc did turn on but there was no output to the display,the fans were all running, the hdd and CD drives were not running and when I turned the pc on the motherboard speaker (Which usually makes a bip sound when i turn the pc on)the was no bip sound.Also as you can see in the video in the front io were the led lights are the red is always on while the green is blinking very fast.In conclusion I found out that the power supply is broken.If anyone knows what else could have been broken please respond.
