blanck screen

I have a HP Pavillion desktop PC that locks up randomly and I need to determine the cause and find a fix. I have tried installing different OS on the machine (Windows 10, Windows 11, Ubuntu) and the problem remains. Most of the time, the PC will boot up normally and then will randomly throw up...

Hi everyone, thanks in advance for taking the time to help me out with this issue! I'm sure ill get a lot of comments saying that my hardware its old and outdated... blah blah blah but please try to understand that its not about the hardware, but a fulfillment of my childhood.. haha THIS IS...
