It's my first post on this forum so pleasre bare with me. Yesterday i tried fitting a new RAM card on my motherboard, and it took me a while to see that it wouldn't fit (though it was a DDR2 and should have). I thought it was in , but it wasn't, and started the PC. Only the cpu fan got some power, spinning for a bit and stopping, same as the hard drive. I've changed the RAM back, but the same probblem. I can press power on multiple times in a row to get the cpu fan to "normal" startup speed, but then it stops again. Figured it was the PSU so i've opened it up to find some popped caps. So, i've changed it, but the same thing happens again. When i press power on, cpu fan spins a little, HDD gets some power for a few spins, then nothing. No caps are popped on the motherboard. Any ideeas would be appreciated. Would like to know if the motherboard is toast, or how i could tell if it is.
