Artifacts on x4500 (Intel 4 Series Express ChipsetFamily)

[idata]

Hello

I've installed drivers from http://www.mediafire.com/?cuy2tjmzjbe new modded driver new version by pavelv15.rar downloaded from http://www.pavelv15.estranky.cz/clanky/modded-drivers.html INTEL GMA -4500m-4500mhd-x4500 help site - MODDED DRIVERS . Since then I get artifacts in Areo interface (only there) and in games. What I've found out is that these drivers overclocked GPU from 475 to 640 (I think so, I'm not sure if it was earlier , tested with GPU-Z). Is there any way to revert back to normal speed? Of course I've tried changing drivers to normal, newest, oldest, etc. What is funny these artifactsI think don't show in windows XP in games (I will confirm), only in Windows 7, GPU clock remains set to 640MHz anyway. Tried also flashing BIOS , since it's laptop, Dell E5500. Please help

Hi there!

The Intel technical department does not support modded drivers at all. Intel recommends downloading customized drivers from your computer manufacturer or generic drivers from the Intel web site.

Thanks

Allan.

Thanks for answering. If I did know I wouldn't use drivers of course. Now I'm not sure what is wrong. I checked graphic card in Windows XP- no problem at all. In this case I think something was messed up with system, not HW and maybe GPU's MHz is correct.

If I would like to reinstall drivers for Windows 7 , from scratch I mean, what should be done? I reinstalled them few times but with no success.
