how do i know if my psu is powerfull enough? its only 350w and i think its why my pc has always been a bit slow i have copied the specs below. can anyone tell me if a hard ware problem is the fault? (i have tried putting in an ATI 6800 PRO, but it didnt work properly and i had large blocks in the screen when playing far cry)

with the current set up i cant play games- even worms froze up! please help!

it os probably best to upgrade it to a 650watt one just to be safe as well if you add any more components it should still be poerful enough

use the lite it's free

I would tend to think it is a graphics card driver problem so if your psu figures check out(which i think are ok)this is where i would start.
the 6800 pro is an nvidia card not ati.If you loaded an ati driver then that's the problem.
If it was a typo, then did you uninstall the old driver before installing your new card.

sorry- its an ATI radeon 9800 pro(club)

also, device manager shows the cpu as a pentium d 2x 3.4ghz

I personally would think a 350 watt supply should power this setup but if its an unbranded one it might be struggling a bit. In short yes, I think the power supply is the problem although I did have a similar problem with a graphics card once and it was the card that was faulty.

The 9800 Pro from memory has a secondary power connector, you do have that connected don't you?

ive just checked and ive got a powerman psu, called 'substandard or dangerous to system' in reveiws!

I would get a quality psu, you can use it in your next pc. good selection at scan.co.uk. one with the 80% efficiency logo will save on your electricity bill.

And if you are going to use it on another PC later on it makes sense to buy a more powerful one than you need so you can be sure it will power it.
