4570 problems - possibly driver

[mribrahimali]

hi, first of all my computer specs.

dell studio 1555 bought in October 2009
Pentium-D t4300 @ 2.1 ghz
4.00 gb ram
vista 64 bit
ATI Mobility Radeon HD 4570

A dialog box came up saying something along the lines of ati driver fail or something like that, then after that all of my games that require my graphics card have simply crashed at the start/menu screen- the one after all the logos and marketing, except tom Clancy's hawx which loads but the display has what appears to be a contained fractal over the screen(messed up shapes).

I have tried updating the video card drivers, nothing has improved. Ran diagnostics in bios, said nothing is wrong, tried reinstalling catalyst control center, nothing happened. I have now sent an email to dell support center.

i have looked at GPU-Z, and it comes up with values for the card so im pretty sure its running - temperatures of about 50 C at a 2% load. windows device manager says everything is fine.

cpu runs at about 40 C on idle

Any help would be appreciated.

p.s. i am a noob when it comes to graphics cards

also, how do you thank other members so it appears under their name on the left hand side of the screen in hexus forums?
