Hey.

Try to Google these and update it if possible:

SCDEmu SCDEmu.SYS Mon Aug 06 20:15:06 2007 (This is for PowerIso - update that to at least 7/26/2009 version 4.5.0.0)
RTKVHDA RTKVHDA.sys Fri Aug 29 05:28:27 2008 (This is for Realtek sound driver - update that.)
secdrv secdrv.SYS Wed Sep 13 09:18:32 2006

You could try to monitor temps with ATI Tray Tools to see if that may be a problem.

Let us know if you find anything out about those two suggestions, or how it goes.

ok i will try thx buddy! ..
but the temps are ok i think i used gpuz to monitorize and its allways fine look the atachment (its playing css)

edit: ive also used riva tunner to unclock 20mhz in all .. let me see if with this and the 2 updates its ok..
greetings
