4870 crashing computer help

[oJaKex]

I installed this board and ever since when i play call of duty 4 or any other game, it crashes my computer straight away. My psu is 750w and it ran perfect on my old motherboard.
What could it be? it worked with my graphics card on my other motherboard so i'm guessing my psu can't pull out enough wattage or something to power my GPU on this board

Can someone point me in the right direction please.
Ima newb so flame off pls

What PSU is it?

It said it was a gaming psu quad rail, but was really cheap, i couldn't afford a high end spec one at that time tho, would you say thats my best bet?

there must be a label on it?

which is actually worrying as all decent brands will clearly state what they are.

So its looking very likely at the moment to be the cause.

OK, thanks for replying without the words "go search instead of getting spoonfed lmao" cheers

Hey

Also another thing to look at is making sure you fully uninstalled the drivers for your previous board. This can cause issues with crashing
