How to turn a small problem into a disaster!

Lucazone, It aplies to all CPUs. If you install a diferant one all you need to change is the CPU Type / Speed settings , nowdays thats normally is CMOS thought when I started with PCs it was almost always Jumpers on the Board it self.

Yeah, it was a P4. I couldn't remove it from the motherboard by using the little lever thingy (getting all technical now!), because the size of the heatsink covered the processor socket on the motherboard. Even if I have to reinstall everything I should be seeing something on the screen, even if it's an error message. The PC's not even beeping at me.

Hi
If you enable USB legacy in the BIOS you'll have contol in both safe and DOS modes.
The differences that people are maybe finding is between XP home and XP Pro....XP home only allows limited component swapping.

if its not even beeping it has either cracked the motherboard as previously said or the cpu is not seated properly, remove and recheck the pins.
Is it powering up ie do all the fans start spinning?
check the cpu fan is plugged in they won't power up if its out.

It's powering up OK. All of the fans are working. I've checked the pins and they are all OK. The processor feels like it's seated OK. Maybe the processor got zapped by static when it fell on the carpet. I think my next move is to take it to a local technician and get him to test it out. I don't want to fork out for a motherboard and CPU when I don't know for sure which one is damaged.

Fans Spinning suggests the motherboards still capable of sending power round the system and it detects a processor in the socket.

So its likley the P4s been zapped.

Retail P4s have a 3 year waranty.... I would be keeping quiet about how the chip died if its in warranty when you go and see a technician!

Which P4 is it one of the smaller newer ones with heat spreader or one of the older larger ones with die exposed directly to the heat sink? (though the dies really the same size)

I once dropped a Northwood about 2 meters onto a lino covered concret floor, and it all worked.

Hi
Not necessarily on a multi voltage MB......does confirm you have 12V though.....as previously mention you should get at least some POST beeps....I dont know the P4 pga....but it once took me over an hour with a celeron straightning pins with a pair of snipenose and a magnifing glass...booted in the end...but its very easy to miss one...and they are very easily bent.

It's one of the older ones. I tried powering it up with the processor out, just to see what would happen, and there was no change.

Jons got a good point there,

Most of my tests were on known good boards with dead processors, or with known good chips and dead boards. In this case you know the status of neither
