Windows 7 keeps freezing - help please!

[smileadele]

Hello,
I have recently purchased a HP m9765uk computer which came with Vista. I have now installed Windows 7 Home Premium and since installing, it freezes regularly. Event ID is 41 Task Category 63. I have not played any games, I have just used the internet, opened windows and played music and video via Windows Media Player and Itunes.
The screen freezes and although music and the mouse continue to work, I can't actually do anything with them. All I can do, is press and hold the power button to power down the PC.
Latest symptom is that when the PC freezes, the mouse cursor (which you can still move around the screen even though inactive) gets a shadow effect and a number of coloured dots around it.
This is the Event property - can anyone tell me what I can do to fix this problem?

I highly doubt Win 7 needs more RAM voltage for than Vista if the PC has been functioning properly before the upgrade.

Try re-installing Win 7.
