1. Jump the cmos (The only valuable thing you'll lose during this is overclock settings or any other settings you changed, which you can set again, shouldn't be to hard.)

2. reseat the RAM

3. Virus scan if you can...

If this doesn't work then it sounds like a mobo problem or a heat problem... If it's dusty try blowing the dust out with a can of compressed air...
Hey what's wrong with stating my os is winxp. Giving me negative pts for this. duhz.
