Intel quad 9450
Rampage formula mother board
Sapphire HD 4870 512MB video card
My problem is that when i enter games my computer just restarts, i think ( know ) that it is my video card, but what other solutions can i try before replaceing it ( no money atm )
And another thing, my computer sometimes just wont start, i have to take out the RAM and put it back in, in order to start, why is that?
