well basically my computer started freezing and crashing, after reseting i was sometimes recieving a 'cpu overtemperature' message and some bleeps before the comp started to load windows, sometimes the computer took ages before it would do anything after switching off the power other times it loaded straight away.
before i got the cpu temperature message i thought the harddrive was over heating so i brought a harddrive fan which attaches directly to the hard drive and that didnt solve the problem then a couple of times later i saw the message so i brought a fan for the side of the case to blow extra air in and i replaced the heatsink and fan.
things improved after that the cpu temperature was running at 86 before i fitted the new stuff and after it was about 76 and the computer worked fine for about a week, then yesterday it crashed again so i turned the power off like i done before but now when i turn it back on nothing happens. all i get is the power light coming on nothing else at all
is there anyone that has had any problems like this before and if so how did you sort it with out having to buy a brand new computer any help is greatly appriciated
