Alright so I put some new thermal past on my cpu put it all back together and the computer will start up for a few seconds but then shuts down. I tried taking the cpu out and putting it back in but it didn't work but when I did do it that first time it stayed on a bit longer but still shut down. After trying that 4 times I checked to see if I could get into bios without the cpu, the computer stays on but nothing is displayed on the screen? I checked the cpu and all the pins are still their and I don't see anything like dirt or past blocking it. So did I fry it somehow?? Thanks.
