Vertical Lines / Computer freezes

[Izi]

I built 2 pc's of exact same spec recently. One is working fine, the other is freezing as above, and the PC has to be rebooted. It then lasts a random amount of time before it happening again.

I took the motherboard / ram back to shop for testing. They said that they couldnt find a problem with it after a couple hours testing. They said that it could be a problem with drivers or a bit of software causing issues, which I call BS.

Is this a hardware fault, or a software fault? Does anyone have an explaination as to what may be causing it?

Thanks in advance.

These are graphical artefacts. It means your graphics card is dead. RMA it if you can, or buy a new one.

thanks for the reply.

Can you explain a little more about this? When i took it back for RMA (didnt get from OCUK) they tested it and said it was ok because the lines didnt appear.

They did say they could test it for longer but said they didnt think there was anything wrong with it.

You said you took the mobo/ram back, did you take the graphics card back?

You could try another cable/monitor on the off-chance, but I've seen this a ton of times, it's always the graphics card.

Usually caused by the graphics memory, or atleast mine was with my old 9600GT

sorry, on board graphics (Geforce 7600).

i'll take it back to them again.

Any sort of banding like this is usually caused by a video memory fault. Has the on board graphics card got its own memory or is it using a portion of the system RAM ?
