New PC build freezes when GPU/case is bumped or moved, sometimes also randomly


TLDR: PC freezes when moving or bumping case or when slightly wiggling GPU. It will also freeze randomly when I'm browsing the Internet in Chrome (doesn't freeze for the most part when gaming). Reseated motherboard/components, replaced PSU, reinstalled Windows 10, tested RAM/CPU/GPU, issue persists.

Last week I built a PC and I've been having freezing issues pretty much since day one. The screen will just freeze, audio will stop immediately, no response and I have to force a reboot. Most times when I reboot, the screen will stay black and I have to either reboot multiple times or pull out the power cable and keep the on-button pressed for 30 seconds before it boots up properly again.

It will happen mostly when I'm simply browsing the Internet in Chrome but it also happened a couple of times when I was doing something in uTorrent or when I was playing a game (The Witcher 3/GTA V). I don't believe it's caused by overheating as temperatures are fine (40C idle and 70-75 under heavy load with XMP profile enabled) and I've played demanding games for many hours without freezing. I've ran memtest for about 9.5 hours (6 passes) without any errors, I stress-tested both the CPU and GPU successfully and I even replaced the PSU when I thought that could have been the issue (had a Corsair RM750X installed previously), but the freezing still persists. Enabling/disabling XMP profile makes no difference. I reinstalled Windows 10 to no avail.

Today I actually took apart the whole computer and rebuilt it from scratch, refit the motherboard on the standoffs and reseated every single component. Still freezing.

I noticed that the same issue occurs when I move the case or slightly bump it. I decided to test this and gave the case a couple of taps with my knuckle on the top side. Both times I did this, the computer would freeze. I also opened the case and starting gently wiggling some components to see if it would cause freezing. Slightly pressing on the GPU would cause the PC to freeze. I moved the GPU to a different PCIe slot and tried the same, the PC froze again. None of the other components caused the PC to freeze when wiggled/pressed.

I'm at a bit of a loss here but it seems that either the GPU or the motherboard are faulty or the case is causing some kind of short circuit? Whenever I slightly wiggle or press on the GPU it will cause the PC to freeze (in different PCIe slots), however, the PC will also freeze if I slightly move the case or tap the case with my hand. How do I proceed from here to figure out what's wrong? Would appreciate any advice.

Please let me know if I've left out any important information.

  1. Have you tried removing the GPU all together and testing the computer with the integrated graphics?

  2. Hi, thanks for replying.

    I just removed the GPU, hooked up my monitor to the integrated graphics and proceeded to give the top of the case some more taps with my hand. Instead of freezing the screen, the screen went entirely black, and it said the signal was lost. The rest is much the same, have to force a reboot. I'm not even using a lot of force and I would expect a computer to be able to handle the occasional bump or shove. Would you say there's something wrong with the motherboard?

    A PC should definitely be able to stand up to little nudges. It is tough to say really what is wrong with it. My next step would be to check the motherboard standoffs and make sure nothing is shorting out or rubbing there.

  4. After some more testing I discovered that the PC would also freeze in BIOS. So I decided to open the case and apply some pressure on different parts of the motherboard. There was one particular part of the motherboard that would always cause the PC to freeze if I applied pressure there so I figured the motherboard had to be faulty. I replaced it with a new MSI Z270 Gaming Pro Carbon motherboard and haven't had any issues since. Runs like a charm. I even beat up the case a bit (not literally) to see if it would freeze and nothing. Problem solved.
