Awhile back my computer started to shut down on me after an hour or two of being on it. Now it shuts off almost immediately when I start it up. I checked for new thermal paste and even put a new power supply in it, but the same thing happens. Any ideas what the issue is?

How do you know it’s not overheating? I thought you were unable to get into the bios to check?
Well awhile back it worked a couple of times but only enough time to watch the temp settle. Now it's gotten worse to where I cant. So that's really the only useful info I have unfortunately.
