Computer wont work!

[samz90]

I have had my computer for 2 years and it looked dusty inside and was giving off lots of heat. I decided to remove the cpu fan and heatsink to remove the old cooling paste and replace it with new paste. I cleaned off the old stuff and applied a pea size amount to the processor and smeared it over, removing excess with a cotton bud. I also removed my graphics card, cleaned it and replaced it. I re-connected the wires and switched it on. The fans run and its sounds as if it is on but when I turn on the monitor I get the'no signal' messege. Please help me! Is there anything I can do. I ensured that the processor was inline with the little triangle, Please help!

Thanks.

ps. when I switch it on None of the keyboard lights work.

why on earth did you bother doing all that?

sounds to me as though you may have transfered some static electricity to one of the components, maybe the CPU. in which case, it's probably dead.

If you are lucky there is either a problem with cabling (which might have come loose from the motherboard whilst you were digging about) or perhaps the cpu just needs to be reseated.

However taking a working machine apart because it is giving off heat is never a wise move - computers generate a lot of heat, and doing so doesn't mean there is anything wrong.

I'm afraid I agree with fo3nix, it sounds like you've killed your machine.

How easy is it to put in a new processor? (I wont do it myself)

hi sam--i work with computers all the time and while what fo3nix and whqttt say is largely true i don't think u have necessarily killed ur machine--recheck all the items u moved/unplugged/disturbed/--often a machine will not boot up if the k/board is not proprly connected--do u get any beeps when it is trying to boot up--on most systems u should have a single shortish beep for a system that is booting ok--other combinations of beeps indicate different things--it depends on what your bios type is--check this site:

post again with more info if ur still stuck--eg machine make operating system mother board bios type etc

You basically already did all you need to do to put in a new processor. Remove the fan & heat sink. Im not sure bout your motherboard but mine has a little arm on the right side of the processor that you lift up and then the processor simply lifts out. Anytime you work on a computer, no matter what it is you are doing, you need to unplug it, then push and hold the power button for a couple seconds and then discharge any static in your body by touching the metal part of your computer case. Keep touching the case periodically to be sure there is no static discharge to vital computer parts.

I dont get any beeps when I boot up my system.

The human body can give off 6000volts of static electricity, 30volts is enough to kill a CPU.

When you say you cleaned off all the old paste, this was presumably from the CPU which you also claimed to have checked was in line with the triangle.Both of these admissions mean you physically touched the CPU and if so did you use anti-static precautions.

The little triangle is only an indication of the orientation of the CPU and any attempt to adjust its position without lifting the locking arm could cause damage.

Finally have you pushed the graphics card securely into its seating, again using A/S precautions as they do require a fair amount of force.

By the way, correct A/S precautions should include the wearing of an anti-static wrist band.

Just fixed it today, only cost me �25, but i'll never do it again!

Give us a clue then!!!!
