    I have a power supply fan thats fluctuatng .Would that cause the computer to freeze up periodically? I have a IPC Computer-800 MHZ-512 Sdram-30 GB HD-Windows XP.Ignore Emachine stats at bottom of post.I have 2 computers.

    If it sounds dodgy, then it's probably packing up. Shouldn't affect the rest of your comp, but I'd replace it asap if possible. You'll only notice that your computer won't boot at all once it's died.

    It could -- if it fluctuates enough that the power supply overheats and shuts down -- or worse, lets its output get out of spec. and forces the system to shut down.

    If it's just the PSU fan, you could replace it. They're usually 80mm fans -- but it's pretty hard to know what airflow spec to look for.

    If the PSU fan is getting variations in the voltage that supplies it, it's time to replace the PSU. Changing the hard drive or CPU fan won't have any impact on the PSU fan or the voltage that drives it.

    You seriously need to get some monitoring software on there to diagnose the problem. Your Emachines page may offer some prorams. I am unsure now why you think it is heat related since you replaced most fans. Newer fans fluctuate with temperature (intentionally) and can be problematic with built in bios tools that expect a certain speed or spit out an error message, so you need tools that show case and chip temperature, because thats wahts important. You can consider some monitoring tools and see if anything comes up: http://majorgeeks.com/download.php?id=11&sort=25

    I would go back to the basics. Remove everything thats bolted on, network cards, sound cards, all but main hard drive and see what happens. Now your down to motherboard, chip, ram and video. From here, re-seat the ram and video card (if its not onboard) to see if that helps. You probably have 2-256 meg chips for ram, so remove one. Next, sadly, start swapping hardware like the video and ram to see if it goes away. Basically you need to trrack down the problem by starting with the basics and working your way back up.

    Appreciate all the help.This is another computer my son gave me so is not this one Im posting with.Ive downloaded some of the suggested tools but its hard to keep the computer going long enough to test so may have to remove and reset some of the hardware.Thank you all for your suggestion. :)
