i have a customer who took it upon his self to clean out his computer from dust. he took off the cpu fan and the proccessor came out with it. he put the cpu back in but bent a couple of pronges on it but bent them back straight. He also didn't ground himself from static either. The problem is now that he has done all of this the computer doesn't start up. all it is doing is the fans are starting but nothing else. i can't even get into bios. Is there a way to at least get it to bios without having to replace the cpu.

also I have looked at it and the cpu seems fine. I have taken everything out of it and reseated everything( ram, cpu, etc.) It does not even have any bios beeps.

But you say the fans are running? Is this an ATX Power Supply or an old AT Power Supply?

If it is the latter the power is switched on when the computer is switched on and if nothing is happening most likely the CPU has been killed.

However if you have an ATX Power Supply the CPU must be working for the power to stay on.

This is where a little more detail would go a long way to help answering your question.

An ATX system can power up with a faulty CPU. So CPU may be kaput. Faulty or improperly seated RAM, bad PCI card and other things can produce same symptoms.

First, disconnect everything nor required for boot. You should be left with mobo, RAM, CPU, power supply, and video adapter (if not integrated on mobo). Then try bootup. If successful, it's a peripheral. Reconnect until you find the culprit.

Also swap RAM. Faulty RAM can also cause no beeps on bootup.

I have bent pins on CPU before and had to straighten them back. Look down lines of pins and ensure that all are straight and one is not bent down flat against CPU. If CPU goes into socket easily, pins are probably OK unless one is broken off.

Don't know about you climate, but in our 90% humidity down South, static straps are not necessary unless working on carpet or with electric strip heat in winter. So CPU probably wasn't damaged by handling without static protection.

Good thought below. If system was powered up without HSF in place and connected, CPU is toast. Time to destruction is 15 sec or less depending on CPU.

No way to get into BIOS without operable CPU.

Sounds like CPU has bitten the dust.

I would go for the CPU being junk, but first check your Video Card, particularly if it is an AGP card (if it has on-board video ignore this) and make sure the card is seated really well.

Check all your other connections, seating of memory, etc and also make sure that the HDD is spinning up and all that sort of stuff.

If you have more than one memory module, strip it down to one module and see if it boots, if not, swap the modules and retest.

Unplug the HDD and remove all PCI cards that are not needed to boot (leave the video card in place if you have one) - in other words, strip it down to a base system without a HDD or CD ROM, and one memory module, then see if it will POST.

If it doesn't, it is probably Motherboard or CPU.

Can you pick up another CPU cheap about the place? If so, swap it and test.

If the CPU fell out as your client removed the Fan, it could be other things fell out as well, like Jumpers? make sure all jumpers of the Mainboard are connected where there should be connected jumpers. Go to the mainboards homepage if you need more info on the board. What type is it, anyway? For which CPU type?
Also, I don't believe the CPU got broken by static electricity, but it could be your customer didn't straiten all pins before he tried it, maybe a pin was shorting another? maybe he didn't attach the heat-sink properly and fried it? These are all quite likely possibilities...
