Hello everyone,

My sister has a server computer that we turned into a gaming computer about a year ago and everything was fine until strange crashes started happening about 5 months ago.

The specs are:
Computer: Dell Precision T5600
OS: Windows 10 Pro 64-bit
CPU: Intel Xeon E5-2660 @ 2.2GHz
RAM: Samsung (non-ecc) 4x8 - 32GB's [1333MHz @ 1.5V]
GPU: Radeon RX 480 4GB
PSU: (unknown brand) 635W
Storage: WD Blue 1TB HDD

A few quick notes:
The computer uses more wattage than recommended, but has never had issue prior.
Problems can occur anytime between 3 weeks apart to repeating immediately upon booting 2-3 times in a row.

The computer has been running fine for almost a year when the crashes started to happen. The computer will be used for long periods of time with no issues, but as soon as the overall system usage drops, it will often crash and once displayed an error message about the graphics card not being found. It has never crashed when put under heavy stress (ex. games with maxed graphics). A very rare occurrence that only happens upon first boot/reboot is when you drag icons across the desktop, they leave behind black space and wherever the icon is dragged is also turned black until you reboot the machine.

To me it just sounds like a possible PSU issue or the hard drive needed to be reformatted. If this is not the case, please let me know if there is another fix or if a whole new PC is needed. I would just replace the PSU, but the highest wattage PSU available is already in that machine.

Thank you,
flaiR

I am not able to test a different PSU because of two reasons:
1: Because the computer was built to use only certain PSU's, nothing that I own will fit in it.
2: The PSU currently in the system has a couple extra cables that normal ones do not have. This makes it impossible to test a different PSU since the newer ones do not have the special cables.
