Help! Graphics problems after blown PSU

[Broken Arrow]

Hi,

My PSU died this afternoon so I nipped out and got a repalcement. The old one was rated at 360 watts and the replacement is rated at 400 so shouldn't have a problem there.

When I boot up I start to get grapical glitches moving down the screen in cycles and the display becomes really unresponsive and freezes up. When I boot in to Safe Mode the problem goes away, as it does when I uninstall the Nvidia drivers that were working fine until now. As soon as I reinstall the drivers the problem comes back.

Has my blown PSU buggered my graphics card?

Viewsonic 17" CRT
P4 2.6

The old PSU worked fine since the PC was new. I put a new graphics card in about 3/4 months back but apart from that I haven't changed anything since it came from Mesh.

The replacement PSU I picked up is a Q-TEC 400 watt dual fan. And after a bit of googling it seems that it has a pretty poor rep to put it nicely. Bloke in the shop said it would be fine.

*sigh*

No offense taken - my fault for being a mug!

So could the underperforming PSU be the cause of the artefacts that I see when I try running my card with anything but the default display drivers then?

Any suggestings for a low cost 400w PSU suitable for a P4 AGP motherboard?

I guess I'll try that tomorrow. If they turn out to be the scum that I suspect them to be, would the following be good enough?

Akasa Ultra Quiet 400W Paxpower Active PFC ATX2.0 PSU - Black Nickel (CA-012-AK)

Comes out at just over £40 with VAT.

I hope your not using it, if so GET IT SWITCHED OFF AND OUTA THERE NOW YOUR WHOLE RIG IS GOING TO BE TAKEN OUT!!!!!!!!!!!!!!!!!

Thanks for the concern! I'll get it out asap, though the system does seem perfectly stable just running the default display driver.

Bear in mind the PC is a few years old and I'm not looking to set the world on fire with it (though the Q-tec might help with that, right? ). The cheapest option that will get me back to where I was before my old PSU blew up this afternoon will do.

Thanks for all the help guys.

A mate just gave me a 400w Zalman he had knocking around and it seems to have done the trick. The graphical glitches are gone and everything is running fine.

Now I will spend my evening visualising the salesman's face tomorrow as I reunite him with the Qtec PSU he sold me. Rectally.
