Today my notebook Asus M50Vn suddenly started to behave weird. While it's connected to plasma via HDMI, everything starts to stutter a bit, which is very inconvenient in videos. It works like this: 0,5 s of fluid picture, 0,1 s of freeze, 0,5 s of fluid picture, and so on.

Situation is the same on primary (built-in) monitor and secondary (plasma), as well as on youtube, VLC, PotPlayer and MPC HC. DXVA and CUDA won't make any difference, choosing different video renders in player's settings won't do the help as well. I've already tried to install older and newer drivers (graphics is Geforce 9650m GT) but it didn't help.

Computer is 100 % virus free, there is COMODO IS for on-access security and I've also checked it with malwarebytes, hitman pro, emsisoft emergency kit, kaspersky tdss killer and CCE. Almost all processes are disabled.

It's interesting because there's no problems when plasma is connected via VGA.

Unfortunately there's no useful system restore points.

Does anybody have any idea what could be wrong? Thanks in advance.

Boot it to safe mode. See if the same thing happens. If it does, there is a software conflict with something in the startup.

Safe mode will run without video drivers, thus it won't detect HDMI and problem won't persist.

Then do it backwards. Disable all under the startup tab in msconfig. It will answer the same question.

Do a restore point. If that fails then reload from OEM media.

You can't tell if it is rootkit free and you can only tell that your a/v can't find any issues.
