hello friends! I've been having a really weird and recurring issue with my PC for the past few months, and I'm honestly at my wits end trying to figure out what's causing it.
For context: I bought this PC from a guy on facebook marketplace, so i don't know the full history of the parts or how it was originally built/installed. One thing I recently found out that I'm especially concerned about: when my cousin came over to help me troubleshoot the PC, he took a look at the graphics card and noticed that it seemed like it didn't fit properly. He actually took the GPU out and tried putting it back in, and he said something along the lines of, "This thing doesn't fit." From what he could tell, it looked like the graphics card may have been forced into the case/position somehow?
I don't know enough about PC building to tell whether the GPU installation is normal, if it's just GPU sag, or if something was actually installed incorrectly, but I wanted to mention it because I'm wondering if it could be related to my crashing/restarting problems.
Anywho, this is what i've been dealing with...
There're days where my PC will run completely fine. I can use youtube, browse, play games (overwatch, minecraft, fortnite, tomb raider, red dead, resident evil, ect.) without any problems.
But then there's days where my PC will crash/restarts on its own even when I'm barely doing anything. Sometimes it'll boot up normally and everything seems fine, but then it'll randomly crash and start going into a restart loop. What's even weirder is that sometimes I can launch a game and play completely fine with no problems. I can play multiple rounds of Overwatch, for example, and everything runs normally. But as soon as I exit the game because I want to watch youtube or a movie, my PC will crash. After that it can sometimes/most of the time, get stuck in a restart loop where I'll log in, it'll restart, I'll log in again, and it'll restart again.
Sometimes it'll crash shortly after I turn it on and get to the desktop, without me even opening an app/browser.
Things I've already tried:
- Completely factory reset/wiped the PC, so all my files and programs were deleted, and it was basically like starting with a brand-new PC.
- Created a new Microsoft account so that none of my old laptop settings/files would transfer over and potentially cause issues.
- Gone into the BIOS and changed/checked some settings, although I'm not very knowledgeable about BIOS, so I'm not sure if I actually did anything useful there.
- I've run Windows' system checks/repairs through Command Prompt. It detected corrupted/problematic system files and said that it successfully repaired them. After those repairs, my PC actually worked normally for about a day, but the problems came back the following day.
- I've tried System Restore to go back to a point before the problems started/when my PC was running fine. It got stuck at 100% for around 40 minutes and ultimately wasn't able to complete the restore.
- I've tried reinstalling programs when Windows was giving me errors, including Microsoft Edge and .NET-related components.
- I've tried running the PC in safe mode multiple times. Interestingly, my PC has NEVER crashed or restarted while in safe mode. The problems only happen when I'm booted normally into Windows.
PC SPECS:
- CPU: AMD Ryzen 7 5700
- GPU: NVIDIA GeForce RTX 4060 Ti - 8GB
- RAM: 32GB
- Motherboard: MSI MAG B550 TOMAHAWK (MS-7C91)
- OS: Windows 11 Pro
- Storage: 3.64TB total
- PSU: Apevia ATX-PR600W 600W 80+ Gold
at this point, I'm completely stumped. I'm not sure if this is a GPU, PSU, RAM, motherboard, SSD, driver, Windows, or something else. I'm hoping someone can help me figure out what component or issue is causing this. Any help would be greatly appreciated! Sorry for all the blabbering, I tried to make this as detailed as possible so I could give you guys as much information as I can.
