Can overheating slow computer?

Hello,

My sisters got a 3 year old computer and she recently complained that it sounds like a race car when she watched videos. i have repeatedly told her to bring her computer home so i can put a new fan in for her but she has not listened. one week ago she told me "the noise stopped, hurray!" i figure the fan gave up on her completely. now she complains that her computer is drastically slower/ some large memory using applications dont work. im wondering if it is possible that some of the memory registers or transistors in either her cpu or grafix card blew out because of overheating. can this happen without rendering the computer completely unusable? can overheating cause temporary or perminent slowing in another way?

Configuration: Windows XP
Internet Explorer 6.0

Hai

"can overheating cause temporary or perminent slowing in another way?"

It's called "throttling". When a CPU reaches a certain "trigger temp", it will automatically underclock itself in an attempt to lower the temp. If the temp continues to rise, it will eventually shutdown completely to protect itself from burning out.

Other than temperature issues, check for viruses & spyware. Use a cleanup utility such as CCleaner to purge all the accumulated internet crap & temp files. Run MSCONFIG to prevent unnecessary programs from loading at startup. And defrag the drive regularly.
