Computer Question

[psihunter]

Ok ok heres a problem which pissing me off and not allowing me to play all me games

Ever since i got my new cpu(and new motherboard) I've been having a problem when ever i do anything on my computer once in a while (or when i start to play a game) my computer locksup or goes brain dead (i dont have keyboard functions, mouse, everything doesnt work) and when i restart it it works find untill i start a game or really do anything I try to play Tribes2 (just a few mins ago) and it locksup 2 seconds after the program starts running

When i tryed a no-sound play it works sort of fine but still locksup on and off but when i got sound it lockups more than without sound

I've reinstalled, formatted, returned the board and got a new one(same brand) WHAT CAN I DO???

my dad even bought memory to see if that fixed it no luck =/


anybody think they know what the problem is and how to fix it?
