Repaired the connector on my HP Pavillion. When I reassembled it, I used Arctic Silver instead of a thermal pad on the heatsink. Surface of heat sink appears to be concave rather than flat. When I booted the first time, connector was loose going to touch pad, so I powered down rather than exiting. After that, computer would try to boot (Windows XP Home), I'd get a blue screen and it would shut down. Shut down so fast I couldn't read the message. I decided to let it do this until maybe it would boot. After about 4 or 5 minutes it shut down completely. Now it's completely dead. No lights at all. I didn't know if the CPU went out if this would be the case. Fan seem to run at high speed and keyboard felt warm. Is it possible the Arctic Silver didn't work as well as the pad and fried the CPU? I don't mind trying another CPU, but if it sounds like this may not be it, would like to know. Thanks to all!
