Computer Lags after Vid Card Install

Intel / D975xbx2
September 9, 2009 at 15:23:24
Specs: Microsoft Windows XP Home Edition, AMD Sempron Processor 3300+ 1 GB of RAM
I gave a buddy of mine my old video card, an
HIS Radeon HD 2600. He installed it this
morning and since then his computer is really
lagging. The CPU usage is hanging between
50% and 70%. Personally, I'm stumped and
Google is less than useful when I tried
searching on it. Any help would be much
appreciated.

From what I can gather form the description of the card, it's an AGP card. Is it the 2600xt? I didn't find amp specs on it, but usually an underpowered or crappy psu could be the culprit. Did you install the latest ati drivers for the card? Post back with the psu specs.

Actually, no, it's a PCIe card. It's the HD 2600, not the 2600xt.
And yes, the latest driver from the ATI website was installed.

My friend doesn't know how powerful his PSU is. It's about 5
years old and is an acer.

Gonna try replacing the power supply. That never occurred to
me. Thanks.

A 2600Pro uses about 3a of +12v power and a 2600XT uses about 4a.

Did your friend follow instructions for uninstalling old drivers and installing the HD2600 drivers?

I imagine we're gonna new quite a bit more information about your friend's system before this is over.

I'm not exactly sure what he's done, to be honest. He installed
the card on his own (I showed him how to do it) and I haven't
looked at the computer at all. I've just been posting here asking
for advice since I already have an account here and he doesn't.

I've got power supplies floating around so I'll throw a new one into
his computer and see how it goes.

Amperage on the +12v rail is the important specification. Shoot for something with 20a (or more...more is better) if using a single rail +12v psu.

Is it possible that his system is running perfectly fine, but he 'thinks' it's lagging because of the low CPU usage?

Low CPU usage is good because it is getting the job done and still has time to rest. :-)

If you haven't even looked at it yet, why are you even considering a power supply change?

Does your friend have a clue as to what he's doing? Which card did he remove? or was he running onboard video? Did he uninstall the old drivers before installing the new card? If he was using the onboard, did he change the necessary BIOS settings? Did he install .NET framework before installing the ATI drivers? Did he update the motherboard chipset drivers?
