My 3d graphics are slow and action strangly on my new pc i built. Someone suggested that my 300W power supply is too low and is causing the problem.

I'm just wondering if it makes sense that the system would boot up fine, but the power supply still be the cause of the slow video card.

heres my specs:
Abit KX7-333
AMD XP 2100+
Leadtek GF4 ti4600
768 MB crucial ddr 2100
80 gb ibm 7200
santa cruz sound card
plextor 40x burner
16x dvd rom
enermax 300w power

Not sure if a PSU will slow down a gfx card, but by the look of your system, that PSU is probably running at near full power. Perhaps it's a good idea to get a good quality 350W or 400W supply anyway.

I agree. I think PSU only cause stability problems but will not slow down a Video Card.

Possibly an IRQ conflict? I had a slow video card until I manually assigned IRQ's in the BIOS and now framerates are 30-40% higher and there are no more intermittent pauses.

OK it wasn't the power supply, a new one didn't fix it.
So, I will try the other video card next. If that doesn't solve the problem, what else could it be?

IRQs, drivers, BIOS etc etc

Any number of issues. Best to make sure the system works with some other card. If it does, you know it's card related (maybe drivers or software), or even the card is duff.

If the problem occurs with any gfx card, then it's possibly BIOS, OS or hardware.
