Videos / audios just buffered, but not plays...

Hello! Sometimes, after I work at the computer for a while, the Flash Player stops playback web video/audio. This happens in all browsers and all sites (youtube.com, x-minus.org and others). I see only as buffering progress line grows, but no playback.

I tried all tips from your Flash Player FAQ (disabling hardware acceleration etc). Nothing helps, except rebooting the PC.

I should mention, that I have very poor PC with Athlon 1333 CPU, 2 GB RAM and 64 MB ATI Radeon video.

So maybe this problem occurs due to overloading and the player hangs.

The question is, how to fix it without PC restart?

OS: Windows XP SP3 32-bit. Flash Player: 18.0.0.160 (latest working with my nonSSE CPU). Browsers: all/any.
