bummer on new setup

[Thatguy119]

Hi, today I build my first computer, specs are as follows:

P5Q-E
E8500 at stock
palit 4850 sonic
4 gigs standard corsair stuff
avarage hdd
IDE dvd drive

Wired it up, booted fine, installed xp home, got to desktop, did video card drivers and motherboard drivers, then took COD4 for a spin. Started fine but about 2-3 minutes into gameplay it stopped, white streaked lines started to appear, then my screen goes into standby and I cant do anything apart from reboot the whole computer. Any idea's whats causing it and how to stop it?

Sounds like a faulty graphics card.
What are the temps like for the GPU and cpu, have you tried another game.
System Ram setup correctly in the BIOS for Timmings and voltage, are you running 4 x 1gb or 2 x 2gb.

Have you tried another game? Try running a benchmark, perhaps 3DMark06 or 3DMark Vantage and see if the same occurs again. What are the temps reported as in CCC? You using the 9.1 cats?

EDIT: lol my n00b typing skills. Beaten to it by RJC.

Running two 2 gig sticks, got voltage right, 2.1, timings are 5-5-5-18 right, odd, Ive tried it on oblivion, works fine, got right out of the sewer which is about 20 mins gameplay. Odd
