Motherboard - Chaintech 9CJSEZ running Windows XP Pro
CPU Socket 478
I switched off my PC which had been running fine.
When I switched it on again a few hours later, there was a couple of loud Beeeps and then nothing.
At the front of the PC there is a small LCD display(?) that tells me the loading sequence i.e. FF c24 etc... now nothing but FF. There was no normal flashes at the USB ports that connect to the External Modem, no black screens showing the loading of windows on the Monitor, all that happens it that the fans in the PC are running.
A week or so ago, I asked about a noisy fan which appeard to be the CPU cooler, I was not trying hard enough to remove it.
When I did remove it (quite easily) the fan came away with the cooling vanes(?) leaving a plate above the CPU with a small amount of paste on it. I could not remove the fan on its own, so I just put everything back, it settles down after a while.
Could the problem be this CPU, the cooler is quite large 90x90mm. CPU Socket 478 (Artic Cooler).
If it is, could I remove it from the motherboard and replace it myself?
If the fan/heatsink was pulled off with any force, it may have disturbed the processor in it's socket.
First try removing and refitting the RAM as per laurie53.
Then try removing and refitting the processor, when you remove and refit the heatsink. When you clean off the old thermal paste, use only the barest minimum of new, spread evenly over the contact area. Too much is as bad as too little.
