A 750w power supply won't put out a lot of heat unless you USE all
750w.  If you put in low-powered parts, the 750 will be barely ticking
along - which means less heat, not more.

Suck 350w out of a 350w power supply and you'll get more heat than you
would out of the same parts and a 750w supply.

Personally, I would test the 750 power supply with a meter and if it's
good, keep it along with the case, drives, CD/DVD drive(s) and
whatever and just replace the motherboard, CPU (optional if your
current one is weak and/or bad), memory (probably replace, it's more
delicate than the CPU) and video card.
