Okay. Let's start with my computer specs:
AMD A10-5800K APU
this mobo: http://www.newegg.com/Product/Produc...82E16813138366
4gb of G.Skill RAM: http://www.newegg.com/Product/Produc...82E16820231190
A seagate barracuda 1tb HD
a Cooler Master 850W PSU from christmas like six years ago
eVGA GTX550Ti
Both the CPU and the GPU have Arctic Cooling heatsinks on them.
okay, so what's wrong...
The computer crashes randomly. I mean completely randomly. Just browsing the internet, playing games, litecoin mining, sitting there doing nothing. 95% of the time the screen just goes black, and the thing restarts. the other 5% it'll freeze up without restarting.
At first I thought it was overheating, hence the Arctic coolers. Even with way lower temps, it still does it.
A little more backstory: I built this rig a few months ago and promptly stuffed my finger in to the GPU fan while it was running. Smart, I know. That's why I got the aftermarket cooler for that. I figured though, hey, i have a cpu with integrated graphics and a mobo that supports it, so i installed those drivers and tried to run it. It was really messed up, artifacting, crazy colors, etc. so I stuffed my old 7800GT in there in the interim. This is when the crashing started. This was only the first day that I had it, so I don't know if the issue was present before.
So I got the GTX550Ti back in there and yep, still crashed. I figured maybe something was going on about it running two different graphics drivers, so I reformatted and reinstalled windows, without the ATi drivers. No dice, same issue.
Anywho, any ideas? At this point I'm looking at the CPU and motherboard and getting pretty fed up so I'm thinking of just buying an i5 and being done with it.
