Custom built desktop PC: MSI B450 Tomahawk motherboard having POST issues

Thu, 09 Apr 2026 15:53:31 -0700

Hey all,

I just bought an MSI B450 Tomahawk motherboard and Ryzen 7 2700 combo.

For some reason the EZ debug lights are showing an issue to me.

The CPU light turns on, then turns off about 2 seconds later. The DRAM light does not turn on at all. Then a second later, the VGA and BOOT lights light up very briefly then turns off. (See video for a visual) No SSD or GPU is installed. I’ve tried CMOS reset multiple times, ran it without the battery etc. it was having the same issue when a GPU and SSD was present, but the issue was more that I was not getting any picture out of my GPU. But the GPU and SSD do work.

I suspect a BIOS corruption, so I’m planning on reflashing the BIOS and see if that will fix it, but I still wanted to see if there was any other ideas for fixing.

Thanks!

iBUYPOWER: Is this only the CPU's cooler problem?

Tue, 24 Mar 2026 11:02:40 -0700

So my ibuypower element 9260 is a few years old and its really fast, but after around a week of use it gets really slow. After waiting a few weeks the fast performance is back. I was a little concerned about this so i just stopped using it but i decided that i wanted to revive it. I checked my CPU temp because the liquid coolers became really loud and sounded like something was about to pop inside my pc, the temp got to 90 C only after 3 minutes of it being idle (i checked a screen you can see if you spam the delete key after powering it on). I ordered the Thermalright Assassin X 120 refined cooler to replace the liquid cooler with (and new thermal paste). So i just wanna know if the liquid cooler is the only thing that needs replacing, i know the proper replacement steps but im still worried if i just wasted money. But then again, the pc still ran fast and the download speeds were really fast it just became slower overtime but became fast again after letting it rest for a few weeks.

Desktop PC: micro SD Card write protection

It might be stupid question to someone but this is bothering me for a gooood while.

If micro SD card inserted into say Samsung tablet and formatted I can not find any way how to reformat it back on windows! but if you insert the same card say in dash cam or other device sure it can be formatted with no issues but when inserted into PC is the same $@$* - you can only access files but not format the card as its write protected! HELP PLEASE…

I have few micro SD cards and this is really annoying as I need one to use with Windows PC..

Beelink Mini S13: How to remove the motherboard

Fri, 20 Feb 2026 06:36:00 -0700

I can remove the cover on the bottom and remove the 4 screws of the motherboard.

So far I was unable to remove the motherboard from the case, because it seems the HDMI and USB connectors are stuck in the holes of the case.

Do I need to bend something or is there any additional screw etc. still attached, which needs to be removed?

I want to remove the motherboard, because the CPU fan is very loud and I want to make sure the fan or heatsink is not dirty or thermal paste needs to be exchanged.

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
