I have an ASUS P4S800-MX Motherboard. It was working fine, but i didnt turn it on in a while. When i did it booted fine but the next time i tried to boot it, only the fans would work. It didnt beep and it wont even turn off or reset. Please help.
That is what everyone else has told me 2 do so it is good advice but ive tried shorting it, 3 different power supplies, i have also pulled out all graphics cards and memory. But still nothing. I am told that is you remove the memory the PC makes a long BEEP sound to indicate the there is no memory, if it does this there is no problemn with Motherboard or CPU, but there is no beep meaning that either my CPU is fried or my motherboard is gone. But i dont wanna get a new CPU and it is actually the motherboard. Thanx for the reply but have any ideas?
The next thing you should try is a bit of a time consuming pain, but it will tell you for sure if its a hardware fault. Completely remove your mobo and psu from the case, place the mobo on the antistatic bag it came in if you still have it and have just the processor, ram, graphics card, psu , and monitor plugged in. Then carefully short the power button pins with a screw driver. This will show if you have a short to the metalwork of the case if it powers up ok.
Its a real pain doing this and you MUST be very careful of static discharge, but its the method i use to determine whats wrong.
