Thanks alot guys. I'm pretty dumb when it comes to computers, so I don't dare open it up and look inside to see if the fan's off, etc. I'll try to listen around the tower though and check my surge/power cable. No storms around here lately. The computer's actually sounding a little quieter than usual, so maybe the fan's the problem. But, it's a brand new (well, not quite, it's a year 2000) Gateway, my OS is Windows 98, it has an Intel 500 MHz Pentium III Processor, and Norton Anti-Virus. I don't even know if I said all that right. BTW, how can a person find out the temperature of their computer? Didn't know that was possible?
