Hello I was trying to clean my comp, so I unplugged all pins from the power supply, then I replug it. Now my computer wont boot up properly. I removed all Hardwares except: Motherboard, 1G RAM, CPu, and FAN. I plugged the 24pin(i think) and 4 pin into the mobo. Now when I boot up, it shows a blank screen, and the CPU Fan spinning as if your CPU usage is 100%, never slows down. I tried to reset my BIOS, no hope. Is it my CPU's problem? Because when I unplug the RAM chip it beeps, so it seems to me that my mobo is fine. Sry for my poor english :o

What/how did you clean? Static electricity can wreck electrical components ?

Did you ground yourself by touching a area on the tower ,also alsways check all your connectionss after you clean the inside of your PC ,and anytime you disconnect something ,write yourself a graph /picture of the pin setup and how it was originially plugged in ! I wish you the best of luch getting this PC up and running ,you may have to contact tohe manufactuer and see if they can send you a diagram of how the pin configuration and the plug should line up ,also a inexpensive multi meter(radio shack) to check if your power supply is still sending a electricial current to the PC ? Take Care ,Nick

If you get beeps with the RAM removed, that 'does' indicate that your motherboard is probably ok. The error beeps are because of the missing RAM. It sounds like you might have zapped the RAM. If you have more than one RAM stick, try one at a time.
