Im so frustrated with this problem, and have no idea what it is. I kept getting a blue screen with the acedrv09.sys error. But it would restart and work fine. Now i get no picture, and sounds like my computer is running very slow. Or almost like its stuck in Sleep Mode. Can someone help me, or tell me what is going on? i got the computer on Christmas of 08. So its not even 2 years old. HP Desktop
Either update Filter Driver ProtectDisc or if you don't even use it (or even know what it is), delete (backup first to desktop or somewhere) acerdrv09.sys and acerdrv09.dll from C:\Windows\System32\drivers.
