SOS --> Dead machine

[travka]

HI!

Problem - Dead machine: no POST, no error bips, nothing on the screen...

How - I changed 66MHz FBS to 100MHz(in the bios setup) on

M741LMRT(http://www.pcchips.com.tw/M741LMRT.html )

for Celeron 533MHz in Slot1(CPU clock on CPU card was AUTO)

After restarting: no POST, no error bips...

CPU, memory (PC100) and PSU are ok (I tested it)!

What to do: to flash bios or what?

Any information or links regarding this would be greatly appreciated!
Thanks again!

Well as long as nothing burned and it shouldnt ahve if you turned it off quick you are ok. First unplug pc from outlet. Second locate Cmos jumper switch. it will say cmos clear or similar. It will be on "normal" mode now. Move it one pin over so it is shorting "clear"...leave it there for a minute. Now move back to "normal" mode. Replug pc back into outlet. It shoudl now boot with bios defauts of 66mhz fsb but you will have to check all your bios settings now as they have all been reset. If you cant find the clear jumper or it doesnt work. Unplug pc, find a round shinney watch battery. Use the retainer clip to release. Leave bat. out for few minutes. It will now be reset. That will fix it if nothing fried.

P.S. Keep fingers crossed.

HI $1500-P4 gamer – You are so fast. Thanks!

So…something is fried?!

I already tried everything you suggest to me but my machine won’t boot.

Any other idea?

Thanks again!

If you can try the cpu in another mobo and see if its o.k. Also pull all the cards but video and leave HDD/cdroms all disconnected. So you only have one stick mem, cpu and video card in mobo. IF still no boot I would say its either cpu or mobo thats dead. You can try removing the cpu and pushing it back in to see if it lost contact due to heat and etc. Worth a try anyhow. Best thing is to try the cpu in dif system if possible.

Depending on how the battery backup circuit is configured, you may have to leave the battery out for longer than a few minutes after you remove it.

You could also just power up the system with the battery out.

"You could also just power up the system with the battery out."

Yeah, that should work. Try that. Some are finiky about reseting. Booting should drain the charge the cmos held. 9-10 though will clear just by moving jumper or removing bat. for a momnet. Worth a shot anyhow.
