Hello! Some days ago on Asus F7Sr with Windows 7 Maximum 32bit there was a following problem: in Youtube or at video playing in Media Player Classic HC from a hard disk playback stops approximately in 30-60 minutes. In Review of events - Logs Windows - Application regularly appears an error "the Manager of windows of a desktop found out an unremovable error (0x8898009b)", and following event - "the Manager of windows of a desktop completed operation with the code (0x8898009b)". A source of events - Desktop Window Manager. Communication between this error and video stop while precisely did not install, but I suspect that video stops when the Manager of windows of a desktop makes a mistake.
Reinstalled videocard drivers (ATI Mobility Radeon 2400 Series) - did not help.
How it to treat?
