Have a Dell Inspiron (2014) with Windows 8.1. Left it on last night. Came in this morning and it wouldn't wake up. Had to powerdown and upon restart it booted normally, but when the desktop came up I got a popup in the bottome left corner of the screen saying there was a drive-error and that the computer needed to be shutdown so it could run a disk repair. Tried, but it was already locked up. I did ctrl/alt/delete and chose restart. Upon restart, the computer went through a length disk repair. I step out of the office for a moment while it processed and came back and there was a pop up that had this error:
Realtek HD Audio Background Process for Vista: RAVBg64.exe - A....(rest unreadable)
-The instruction at 0x40028e28 referenced memory at 0x00000000. The memory could not be read.
-Click on OK to terminate the program
-Click on CANCEL to debug the program.
I tried both options. Both make the pop up disappear but give me nothing more than a black screen in permanent lock. I have to press the power button to completely shutdown, let it rest and then restart. I have only tried twice, don't want to cause anymore damage, the popup is currently up right now.
Any help would be great. Thanks!
