My computer started shutting off on its own. It happened 3 times before I cued in. I installed HWMonitor from CPUID and it said the AUXTIN temerature had a high of 170C even though at the moment it was at around 70C.
Thinking it's a cooling issue I looked at the heatsink and one of the 4 legs pinning it on the CPU was broken, thus making a less than perfect contact. So I bought a new heatsink of similar grade, applied a new coat of thermal paste and put it back together.
Now when I start my PC I don't get any video. I just tried another video card and it's the same problem so I don't quite know how to proceed from here. No beeping, and the monitors say Check Signal Cable.
The motherboard doesn't beep.
Specs I can't be more specific without booting the thing and checking the system info. It's an older machine so I don't have the papers anymore. Mobo: ASUS P7P55D-E-LX CPU: Core i5 Heatsink: Deep Cool HTPC-200 (About the same size as the old one) Video: Asus card. I think it's 1Gb and it takes a single additional PCI-E power input. PSU: Stealth XTreme 2 500W RAM: Corsair Vengeance 4x4Gb

More aboutchanged heatsink boot anymore
It seems that your motherboard or processor died, since you tried a different videocard and it did not work. To make sure, you will need to test these components.

Are you positive your cooler is compatible with your cpu/mobo and that it is sitting tight against it?
