Situation: Computer was working perfectly fine, wanted to do a cpu swap. Upgraded from E4300 to Q6600, press power button and computer shuts off after a second or two.
I've built a dozen computers and this is the first time this happened to me. Decided to upgrade to Quad Core. Received the Q6600 today so I decided to install it... I set my Bios to set default settings and cleared CMOS. I removed the heatsink and E4300, applied arctic silver 5 on the Q6600, put the heatsink on, plugged in the cpu fan connector and now the computer won't post. I have a Gigabyte P35-DS3R Motherboard (with F10 Bios which supports Q6600). So I'm thinking that there might be a short somewhere or maybe it's the case power switch.
So I remove the motherboard and only leave cpu, ram (4 sticks of 1GB PC6400 DDR2 - I remove all but one stick), video card in on non conductive surface (wood board). I turn it on with a flat head screwdriver on the 2 power sw jumper pins... and the same thing happens. So I remove the Q6600 and put the E4300 back and still the same thing. When I remove the 4pin 12v next by the cpu, it stays on (all fans moving) but no video is displayed. I swapped out the video card 8800GT with a 8600GT I had lying around, same thing. I swapped out the Ram and put 1 stick in each slot, same thing. Everything else was working fine so I'm thinking it's either the power supply or the motherboard (the only two parts where I don't have a spare to test). Anyone have any ideas? Thanks.
