OK, so I was cleaning the inside of my Desktop (so possible static elect.) and removed the CPU, fan and heatsink. I installed it back in the motherboard, thought the clamp seemed tight but it did lock so expected all to be as it was before this cleaning. The fans come on immediately as I plug the unit in, before I even push the on button but nothing else happens including the indicator light in the power button. No screen or beeps. I checked all the plugs even though I had not pulled anything else so I removed the CPU again and saw some of the pins were bent. I bent them back and replaced it. It went in nicely so I think it lined up right. No difference. I bought a new CPU thinking the bent pins killed the original and carefully put it in. Again, fans only. I pulled the new CPU out and pins look good so I feel it too went in correctly. That's where I'm at.
The questions are: It's probable the bent pins kept some, if not all of the CPU's contacts from doing their thing. If power goes to the MOB without full CPU contact could it kill the MOB? With the same scenario, could it have hurt the power supply? If I replace the MOB, CPU and power supply is there anything else it could be? If I do replace the MOB how will I know it was the problem since it seems I need to do a clean install of the OS? Will it at least power up? Also, I bought this computer with Vista installed with a free upgrade of Win. 7 when it came out a few months later. What I have is the recovery disks I burned of Vista using Gateway's prepare a recovery disk software and an upgrade disk from MS. Will my recovery disks work as a reinstall of Vista and then should I use the upgrade disk to get it to Windows 7?
Thanks to all who have any thoughts as to how I can get this computer going again. This is a computer I paid $360 for only a little over a year ago and am trying not to send to a repair shop and pay $360 after diagnostics, parts and repair costs.
