Running Windows 10. So I start up my computer and within a period of time (usually 3-5 minutes) the monitor will go dark, all sound will stop playing and inputs will stop working. After about 30 seconds, sound will return for about 5 seconds, then become extremely choppy and erratic before quitting out again. After that nothing happens and I have to manually shut down and restart the computer.
I tried running Ubuntu from a flash drive in case it might be harddrive related, but the problem persisted, although the first time I ran Ubuntu it took 14 minutes to freeze, on subsequent boots it took ~3 minutes like on windows 10.
I've also tried reseating and inspecting basically every cable and part on the computer and have tried four separate sticks of RAM individually, with no positive results from any of those fixes.
Sorry if this is the wrong subforum, but it's definitely hardware related so I figured this was the best place to post.
