My system restarts after login or at login screen as soon as I enter password, however it works perfectly fine for hours on Safe Mode. I have tried everything I could find online, posting here just to understand the issue.

  • Went to safe mode, removed drivers, came back installed old drivers, Crimson ReLive Drivers.
  • Disabled restart on system failure
  • Disabled Windows Updates, Disabled Automatic installation of drivers
  • Flashed motherboard BIOS to latest
  • Flashed Graphic Card BIOS to stock, tried the secondary BIOS switch as well
  • Tried changing the graphics card to 1050TI, same problem there.
  • Tried installing the windows and same problem there.
  • Tested the RAMs using memtest, replaced the RAMs.
  • Changed the slot of my graphic card - this worked and I was able to install and run latest AMD drivers, and the system was running fine for about 4-5 hours and then the same thing happened.
What can I do now ? How can I diagnose what the problem is so that I can fix it, may be replace some hardware if its causing issue.

My PC Details:

Lenovo S30 - 056851U
Xeon E5-2670
24 GB RAM (16 + 8)
2TB Segate + 250 GB Samsung EVO SSD
XFX AMD Radeon Rx570 8GB - Connected to 3 27" Displays through DP Ports
Windows 10 Pro for Workstations

Was the system working fine before?
You said that changing the slot of the graphics card worked temporarily- I would suggest using the integrated GPU but I don't think you have one. If you use that (apparently) better slot without installing the latest AMD drivers, does it work for more than those 4-5 hours?

Also check the settings in the BIOS and the GPU BIOS- Sometimes some random option causes this kind of thing.

And this sounds basic, but everyone can miss it- Check for malware.

I dont have a integrated GPU. The better slot worked fine with the drivers installed for 4-5 hours. Now it driver or no-driver the better slot is giving the same issue. The system was working fine previously, I have been using for about 2 years now, this started happening randomly.

A fresh install on a new drive is also having this same problem, so I doubt this is software related. I feel like this is either motherboard or PSU, just wondering if there is something I can do to validate this.

Right, forgot about that- sorry. It definitely sounds like a hardware issue to me. Running it in Safe Mode probably puts less stress on the system, so it runs, but when running it normally once it reaches a certain point it shorts out. This is total speculation, just to be clear.
One thing I don't see you having mentioned was the PSU.
