mobo- nForce 750i
video- Geforce 8800GTS
CPU- Core 2 Duo 3.0ghz
Ok so I ordered some RAM and installed it, a few minuets in to running my pc it blue screened, so I rebooted ran a memory check on the new sticks and found out they were bad, I removed them put in my old sticks and tried to reboot but now the computer would power up but nothing happens. I tried puting the sticks back in, swapping slots with different combinations of my old RAM, that doesnt seem to be the problem.
I noticed that my CPU overheat light would turn on the second I powered up my comp, I felt the heatsink and it seemed to be cold, I took the heatsink off leaving the fan connected to the mobo and felt the cpu (yes I know its dumb but look past that) it never even got warm when turning on. I tried disconecting anything that didnt need to be connected and no success. I even took out the procesor before I turned it on and the led was still on and nothing changed. Also my mobo has a display that will give an error number when it fails to boot but it is displaying FF which is the code for no problem detected.
No matter what I disconect or whatever changes I make I dont see a difference in how it fails to boot. All my fans turn in, including the CPU and GPU fans. My hard drive sounds like its doing something, my cd drive led flickers but the screen stays black and it doesnt do the single beep that ussually indicates a successful boot.
I would have to guess that my mobo is dead, I tried reseting the BIOS, but I dont see what had changed in 1min of me swapping out the RAM to RAM that I knew worked. I am trying to get my hands on another CPU fan to see if mabey the mobo thinks mine is broken and so it refuses to start. I surfed a number of other forums and none of the regular solutions seem to help. I was wondering if anyone has had a problem like this or might have something else for me to test before I buy a new mobo, thanks in advance for any advice, sorry for the long post.
