I have just bought a new computer, here are the specs:

4GB DDR3 RAM; AMD Athlon X2 260 2.1 Ghz; Nvidia GeForce GT 220 1 GB

I have installed the newest Adobe Flash version and the HD videos on youtube (both 720p and 1080p) worked just fine on Windows 8. However, this is not the case under Windows XP. The HD videos on YouTube, Vimeo and on the other sites lag and it seems as if the CPU is at 100% (this is NOT because of the internet connection). I have tested a few HD videos on VLC Media Player and they work just fine.

Could it be because I'm using a 32-bit Windows XP OS on a 64-bit PC? Any ideas?

which browser do you use? – fguchelaar Aug 28 '12 at 12:59
Google Chrome. But it's the same on Firefox and Opera. That's clearly not the problem. – user1020567 Aug 28 '12 at 19:05

It could be Windows XP. Windows XP doesn't address RAM properly. The memory limit for XP is 4 GB but WinXP Starter Edition is only 512 MB. Windows 64 bit OS are better at remapping RAM over 4 GB to your graphics card. That said, XP could also be disabling 2 GB of your RAM.

If you say the videos work fine on VLC, then it could be a problem with hardware acceleration.

Disable Hardware Acceleration: 1.Click on Start 2.Click Control Panel and Click Display 3.Select the Settings tab and click on the Advanced. 4.Click on the Troubleshoot tab. 5.Disable the hardware acceleration completely by dragging the slider to the extreme left.

I've ran out of ideas so I simply reinstalled Windows XP and it started working properly. No idea what was the cause - strange.
