View Full Version : dead cpu
4th Mar 03, 5:13 PM
My workmates sister did a bad thing to his pc the other night, She decided to see what would happen if she switched the power supply from 230 volt to 110 volt whilst the pc was running :dolt:
Anyhoo. A new motherboard, psu and hard drive later i have a problem, the computer refuses to boot. No boot screen, beeps or anything. The motherboard powers up, the psu fan spins as does the heatsink fan. I've taken every card out, replaced the ram with a known working stick, still no joy. Has the cpu gone tits up?
syst specs are
aopen mx3w mobo (onboard sound and vid)
intel celeron 633 processor

Um, i know this is a stupid question, but did you switch it back, and does it still work?

yea the stick i put in still works as does the original - i checked both on my pc with no probs, The only thing i cannot check is the cpu. :rage:
the ram and cpu are from the blown up pc

I think what he meant was did you switch the PS back to 230v.
Why can you not check the CPU? Just pull it out and see if you get a POST code for a missing processor. If you get a code without a proc. and don't get one with it and it still won't boot, try a different processor.

I would tend to think your workmates sister has created a new processor keychain. In other words it's probably dead.

Well, let's put it this way... it's either the cPU, the RAM, or both.
Given the fact that it still refuses to boot when you change the RAM, it must be the CPU that's faulty, no?
And as Dan says, looks like a nice Celeron CPU to add to your keychain.

yep, its the cpu, managed to borrow another proc to test the mobo, it booted up straight away.

Thats besides the point. Maby when s/he switched the power allocation she might have interupted the power flow of the computer at a crucial point. In Other Words, The human heart has several diffrent stages in its pump, like a piston of an engine. If say a light impact were to strike the heart at a certain point in the beat the heart would stop because that impact interupted the pattern of the beat and that person would have somthing like a heart attack, and the person would die. (that vunerable point is about 1/10,000th of a second, 1 person every 5 yrs dies from this so dont worry) Now how does this relate to the computer. When u cut off/reduce a cpu's power while it was on at such a point where it was making some cruicial un-orderd operations it would die and or fry.
TIP: dont ever switch the power feed of a computer while it is on, it might not die but it could damage the motherboard and other key components.

"his" does not refer to "sister" it refers to the workmate
Fred's sister did a bad thing to his PC the other night...
What is funny about that?

Actually, that's "Pronoun Police", to be overtly and uselessly pedantic.

If you haven't fixed it yet, do this:
Open up your case, and take a look at your motherboard.
There should be a small lithium battery on it. Take it out CAREFULLY with something like a toothpick.
Wait about 5-10 minutes. During this time, your computer is resetting it's BIOS configurations. Because your computer will not start so you can mess around with the configs, you will want to do this so it resets itself internally.
Put the battery back in, and start up. If it doesn't work then....you're screwed.
Buy a new computer, then gg :D
