(Please bear in mind that I'm fairly computer-illiterate, but am trying really hard to learn and understand, and I even run a quite busy website).
Anyway, I've noticed that over the past few weeks my cpu is very unstable (gets up to 380+ then can suddenly drop massively down til it can even get to '0'...which is when the computer just 'freezes' and I have to do a hard shut-down and subsequently lose much of what I was working on
).
I just read in your FAQ's about CPU and 'Heat Sinks'...Gulp. I think I got the gist of it, and cleaned (as much as I could without opening the Tower; unplugged everything and re-plugged). ( I would mention that I'm in a rural area and so, not much in the way of local tech assistance available).
Would appreciate any assistance.
Thanks.
