@john1888 Good news about the fix. Glad we could be of help. If you just reseated the heatsink over the cpu after cleaning it without re appling some thermal compound between the mating surfaces it may be a short lived fix and you may have more problems in the future as I found out to my cost. I had to buy a new processor after toasting one when I forgot to re-apply!! *groan*. Bit like going with out sun screen in the sahara.
