Good day. I hope somebody can help with this as I have exhausted my limited computer skills trying to fix it. When I stream a video from the web (e.g. youtube, CNN etc.),usually the first clip of the day works OK in the small window. Subsequent clips or expanding a clip to full screen tend not to work. The clips become choppy and the video/audio are not in sync. It seems small clips (less 2 min) work better than larger clips. Even if a clip is playing well, it tends to get worse with time. This happens whether I use Adobe Flash Player or Windows Media Player (WMP) although Flash seems to have more trouble than WMP. This is a 2004 Dell PC and this problem has just started. When I monitor the problem videos with Windows Task Manager while they are playing, I see that 100% CPU is being used. My anti-virus (McAfee) uses a lot of CPU as things boot but this is transient and quickly falls to 0. The Task Manager shows the browser(Chrome)using all of the CPU. It does not show anything else using significant CPU. Chrome shows up multiple times under processes in Task Manager. I have tried using MS Internet Explorer to watch the videos and it has the same problems as in Google Chrome.
The PC runs WIN XP SP3 with Pentium 4 @ 2.8GHz with 512 MB DDR SDRAM @ 333 MHz. The Flash and Media players are up to date. I use Verizon FIOS and several tests show the download speed to be >25Mbps.
My daughter also has a 2004 Dell PC of essentially the same build and Flash/WMP videos play fine using 25-35% CPU.
Any ideas for fixing this will be greatly appreciated.
