0x124 BSOD on win7

Reznik

I have a win7 tower that I built bout 6 years ago and haven't had any major issues with it til now. I moved, packed the tower up in its original box, set it up at the new place, and now it's giving me BSODs.

It will boot and I can log in but 5 to 30 min later it will give me a BSOD. Doesn't matter what I'm doing. There will be significant slow down before it fails.

If I try to reboot after it fails it gives me a cpu heat warning. I have to wait at least 10 min.

The cpu fan is working and the temp while.running according to speedfan is around 50c.

It's a 3rd gen i5 with 16 gb RAM. Nothing overclocked and no new hardware installed. Nothing useful in event logs.

I'm going to clean it out and put new thermal paste on but I'm confused as to why all of a.sudden it would be overheating. Any ideas?

Edit: it fails in safe mode too

Reapply the thermal paste as a first step, moving PCs around causes the fan to jostle loose a bunch. What about an external component like video card? Any of those or is it all onboard?

I do have a video card, gtx 560 ti. Could that need to be re seated? I haven't noticed any graphical oddities.

124 seems most related to gpu's from what google is telling me, but it's just a general hardware failure so at this point it's reapply thermal paste and reseat the fan and start swapping out components to find the problem child.

Alright, I'll start with the thermal paste and see how it goes. I wanted to build a new machine anyway so this might end up being my excuse to start.

If your motherboard has video out, you can plug your monitor into that and remove the GPU. Use it for awhile without the GPU and see if it still crashes. If the crashes go away it's probably a problem with the GPU (although it could be a power problem that's being 'solved' by reducing your power draw). If it sticks around it's gotta be something else.

turned out two of the pegs holding the cpu heatsink/fan popped out, so it looked like it was attached and was spinning up but probably wasn't even making contact with the CPU. I didn't even need to apply new thermal paste. popped that sucker back in, liberally applied air duster, and now everything is legitimately reading 20C cooler.

(still gonna build a new rig tho)

Super common for that to happen when you move PCs in a vehicle actually! (that's why prebuilt PCs have those weird foam inserts usually)
