Is there a way i could find out if any of my hardware is overheating.......I heard something online with a program you could download to check if yhour video card is overheating etc etc Thanks for the help

If your hardware and if you have one of the newer video cards which supports temp. monitoring this is a good freeware program to use and I use it myself with no problems.

i have a geforce 2 mx 400

Sorry there's no way that card has a chip in it for temp. and fan monitoring. Could get a newer video card if that one is giving you trouble if your into gaming or movie editing stuff.
