hp 8510p: error @ CS:S video stress test after mobility modded radeon mobility HD2600
after reading some very negative comments about the video drivers offered by HP for mobility radeon HD2600 on my 8510p notebook, i decided to use the mobility modder by driverheaven.net. after doing everything following the instructions, i rebooted and started steam (counter strike source) and started the video stress test (in order to compare the fps with the test done some hour ago with the HP drivers). then an error message regarding the "device driver" appeared, followed by an "the instruction at... the memory could not be "read"." error. when trying the video stress test again, counter strike source just disappears now..
when trying to play the old counter strike, it says the video mode is not supported, will use software mode.
any advices about how to optimize my drivers/gfx performance (without using any omega drivers etc.). hope, i can avoid those HP drivers..
