Windows 7: Event viewer warning

Sorry here u go.

In this particular snip, theres nothing very abnormal. DWM is consuming 5% cpu which is somewhat high. Also, you've got wmp and the sidebar running. Did you take this snip in a slowdown? If yes, try switching to a classic (non-aero) theme and cut down on some Visual effects and see whether it solves the problem. Also make sure your video drivers are upto date.

i wonder if this problem has to do with this thread?

this snip is during normal activity..BTW this has not occured these many days.why has this problem started all of a sudden

Google repeat errors in Performance log accessed by clicking WEI score link at Computer>Properties, then clicking Advanced Tools. Look for cued issues at top of Tools page, Generate a System Health Report.

Click the Advanced link at Computer>Properties then in Performance>Settings uncheck visual effects for fading, sliding, dragging intact which may be sufficient. You may already be warned about this on Tools page.

Whenever there are hangs in Windows 7 I would also test my RAM with memtest86 for 5-6 passes and test HD with maker's diag/repair full CD scan.

NOpe.

Ya I got a message in tools that performance can be improved by changing visual settings.
