Abit IP35-E Accident

[pololop]

I have an Abit IP35-E motherboard. I was moving the case while the computer was turned on and unfortunately a some cable touched the CPU fan and the Computer shut down. Every time i try to turn it on again it seems to start but only for about quarter of a second;P When I unplug the 4pin cable powering the CPU (The closest one to the cpu) all the fans are on full speed but the computer isn't starting:/

Some other maybe useful info.
The power supply is Chieftec 450W with only 4pin cable while there is an 8 pin slot for the CPU on the motherboard(it worked fine for about 1.5year before that)

Any suggestions? :/

Did it shut off right away or did it run for a while and then shut down?

Try unplugging all power cables and plugging them back in.

Maybe reset CMOS?

It shut down immediately.
I pulled the battery for a while and unplugged everything and plugged it again and still the same.
When I plug everything I turn the power supply On and the red light turns On, after that i push the power button on the case and the green light lights for a fracture of a second and turns Off again(the fan from the graphics card moves just a little)
You think it might be something with the Motherboard or the Power supply? OR something else maybe?

It might be worth pulling everything out of the case and bench top testing it. Something might be causing a short with the mobo (piece of metal, screw, etc.) or possibly bad connection with case power switch on mobo.

I had a mobo once that had the same symptoms. Turns out the power switch wire from the case was shorting out on some metal causing it to shut down immediately.

Yeah...strip the board bare outside the case. Reseat the CPU. Connect only mouse and keyboard. Reset CMOS. If no POST, then remove the battery for one day. Repeat + rinse. Still dead? See if you can boot with a floppy to reflash the BIOS.

It's possible that one of the pin on the PSU is not making contact with the board. Try another PSU.

OK Ill try that tomorrow because I'm from Poland and its night in here;P I"m very thankful for the advice. hope it works and ill let you know if it works as soon as its done.

Well... I have striped the board, reseated the CPU, reseted CMOS. Took out the battery for about 6 hours (maybe to short?) still the same. No boot. Just the 0.3 seconds of normal response and dead! I will have to check it out with another PSU I guess...

Seriously people, there is no need to take the battery out for hours or days. Just read the motherboard manual and look at the instructions for clearing the CMOS. Typically there is a button you need to push or a jumper you need to move, and in some cases turn the system on while its moved. Clearing the CMOS should be a 1 min operation at most.

Believe me or not, I have had a problem with a faulty USB front-port cable bringing down the whole mobo. Once I had that unplugged, everything worked like a charm.
I am not saying you should do the same in your case, just telling you not to leave any stones unturned! Don't take anything for granted and unplug EVERYTHING not absolutely necessary for POST.

To tell you the truth, later I had a problem like yours, but my board already had taken some physical abuse and had been inadequately repaired to be put on a life support. Since you probably already took the mobo out of the case anyway... check the underside of the board to see if any traces are cut, burnt or exposed showing thin copper strip.

Yeah...strip it bare (mouse, keyboard, and monitor). Avoid USB if possible when troubleshooting. Worst case, you should be able reflash BIOS with a floppy. Use 18 BIOS.

Shorting the CPU fan header could damage the board beyond repair.
