Hardware GPU problem, perhaps?

[Anon10W1z]

I've used my home-built PC for only 3 weeks or so, and I'm already having problems. The latest one is that my GPU (that I've had for 2 weeks) is not working. No output on the screen. The IGP works fine, however. What could be the problem? And BTW, I have a Geforce GT 430 with the IGP/Graphics card setting on "Auto" in the BIOS.

How many beeps when you start up? And what's your mobo?

1 beep from a Gigabyte GA-Z77-D3H

Maybe the lane is messed up?

What are your specs?

Problem fixed itself, when I went to test HDMI, not VGA, it worked. VGA (what I normally use) also worked later.

I have GT 440, not actually same story
but I suspect it's because bad cooling design (a.k.a overheat)
if I touch hsf it's cool, but not if you touch the chip.

my system usually locked up after few minutes playing 3D games.
no problems with 2D. or 2.5D or any games didn't depends on GPU badly

I want to sell it, but I'm affraid it just become problem for person who buy it, and it become burden for long term eventually that person will return it to me.
