Hi all i upgraded to windows 7 64 bit on a NCE powermate 5030 computer and I'm having a problem.

when the computer wakes up (from sleep) I get some white lines on login scenn and UAC popup. if i turn on the aduio its produces a sreeching and painful noise. I'm hoping it is not a hardware problem. I'm in the process in reinstalling the drivers.

I need ideas and help. I have no problems before i put my computer on sleep and using a usb headphone (different driver) the sound seems normal.

BTW the painful noise is coming from the speaker directly

update: ok I reinstalled the audio driver and the white lines are gone...for now
