I will be operating my laptop like normal when it makes a sound similar to if I press the hard power button. ... "PEEHHWW"
Once it does it once it gets very bad the next few times. I am forced to manually power it down (makes the same noise when I do) since it is frozen and when I restart it it usually freezes immediately.
Sometimes I can be on for an hour with out any problems.
I blew into the fan a few months ago and this seemed to solve the problem temporarily. Could have been a coincidence.
EDIT: I forgot to add that periodically after this happens, upon startup it tells me that "OPERATING SYSTEM NOT FOUND" "CHECK CABLES"
Laptop is a Gateway 200x running Windows XP with 512 ram and a 40GB hard drive.
