Problem description: Like the title says, my CPU is massively overheating in my desktop. It's been running fine for a few years, and I don't tax it (web browsing, Office, VLC is about it, sometimes an old game). Maybe 3 weeks ago the system shut off randomly. I thought it was weird, turned it back on, it almost immediately powered off again. The heatsink was scorching hot to the touch. I let it sit overnight, turned it back on the next day, after ~20 minutes the same thing happened. It's been off for two weeks since I've got a backup laptop but I want to get this fixed and don't quite know what to do. Attempted fixes: Cleaned out the entire case, took the fan off and blew out all the dust (there wasn't much at all) from the heatsink, left it off for ~2 weeks but when I turned it on today the CPU was hitting ~100C at idle so I just shut it off again. Recent changes: Not a thing, it's been totally fine for years and I haven't even moved the box for months. -- Operating system: Windows 10 System specs: It's an AMD Phenom II X4 975 processor. 8 gigs of ram, an older Radeon graphics card. Location: US I have Googled and read the FAQ: Yes

You're sure the fan is working?

Did you check the thermal paste?

It spins up when the machine turns on, it runs a bit slow but I don't know if that's the pwm doing something weird with it. it's definitely capable of high speed still. dkj posted:Did you check the thermal paste? This I have not checked out, does the paste dry out eventually? Paste is cheap enough, what would I need to clean the old stuff off the heatsink/processor?

welp I've got the razor blade and alcohol already so that's cool! I'll pick up some paste and report back when I get a chance to do a full cleaning (gone this weekend).
