Managed to figure out the board was a 7VKML before spotting your last post (That will teach me to read down to the bottom of the page next time!)
OK, found the manual for your board which helps. Firstly, we ought to address the CPU issue - i.e temperature & also exact model. I can't find anything for 12777, where did you get this number from?
I'm asking mainly because the motherboard has a hardware jumper for the cpu FSB, as opposed to a software autodetect one - so we need to make sure this is correct. If the cpu has beeen inadvertently overclocked, then this would explain the high temperature.
I'd also advise that you renew the thermal compound, especially as you may need to remove the heatsink in order to read the model info written on top of the cpu. As soon as the heatsink is removed, the thermal compound should be renewed before the computers is switched on again.
a tube of thermal paste (easy enough to come by in most computer stores or even eBay).
some isopropyl alcohol
a clean lint free cloth (a paper coffee filter is good)
a clean plastic scraper (eg credit card or similar) or a clean razor blade is best.
Disconnect the power supply from the motherboard
Remove the heatsink/fan assembly & then remove the cpu
Be careful not to touch the cpu pins and if you need to place it something temporarily, make sure its a suitable surface such as cardboard (nothing that picks up static!)
Use the isoproply alcohol & cloth to clean the cpu die (raised rectangular bit in the middle) & remove all traces of the old compound. Do not touch the die with your figures at any time to prevent contamination. Now that the die is clean, make a note of all
the info thats written on the top of it.
Clean all the old compound off the underside of the heatsink.
Place a small blob of the new thermal paste (about half the size of an uncooked grain of rice) onto the centre of the die then use the razor blade to spread over the die in a thin layer, place the cpu back in it's socket & lock in place with the lever.
Reinstall the heatsink & fan
Let me know what was written on top of the cpu!
