I had Windows 7 installed all september. But I installed Windows XP Professional back because my computer couldn't handle the new OS.

After first boot I tried to install newest flash player (from Adobe website), but it failed. I had my old setup on USB drive and it worked. I don't know is it important or not.

I am watching Youtube videos in my free time (almost every hour). After few days the computer started to freeze when I open a page with the video or close the page with video, not while I watch a video. No BSODs. Nothing in Event viewer. I use Firefox only.

When computer freezes the sound wont. If iTunes is playing a radio station or is it another video playing in background, the sound wont freeze.

Last few days the mouse wont freeze. Its a strange symptom. If I click few times then the cursor will actually freeze.

I just want to know where does this problem come from (hardware - graphics card, old motherboard or it's just some glitch in setups). If it's not graphics card then I will be happy. The graphics card is ATI Radeon HD 4650 - brand new.

Catalyst 11.8 installed.

Things I have tried:

  • Installed newest flash player after a week (the setup didn't fail this time)
  • Installed latest video drivers
  • Deleting cookies
  • Defragmenting hard drive
  • Using TuneUp utilities for computer cleenup
  • Installed latest Mozilla Firefox
  • Cleaned the PC
  • Changed CPU Fan speed almost to max (just to be sure)

Things I haven't tried yet:

  • Didn't try playing videos on other browsers

What can I do now?

Sound like your graphics card (video freezing but sound continuing). You can perhaps try to perform some disk checks and memory tests to rule them out. – Ƭᴇcʜιᴇ007 Nov 8 '11 at 19:18
@techie007 could you tell what program can I use to test my video card, please? – Little Helper Nov 8 '11 at 19:20

Try right clicking the video while it's playing, and Uncheck "Enable hardware acceleration".

Thanks never thougth of that, but now I need to open a bunch of videos to try it out. – Little Helper Nov 8 '11 at 19:48
I think the problem is gone. The only problem that sometimes video lags. – Little Helper Nov 8 '11 at 20:13
@Roberts The lag might just be your computer hardware – Simon Sheehan Nov 8 '11 at 20:31
@Simon Sheehan I know, that's why I used the "old-hardware" tag. I have old but still functional PC, with new video card. So Im woring about video card. – Little Helper Nov 8 '11 at 20:33
Maybe driver roll back will solve the freezing, but I don't want to use old drivers because I had them installed about month and video card was randomly crashing and it was hard to do something. You can check my other questions and you will find out a lot of problems with old graphics driver. – Little Helper Nov 10 '11 at 13:11

Try a LiveUSB to see if it still occurs. If so, likely hw. Better yet, install Linux on the machine as well so you can dual boot.
