PC freezing
I installed a series of updates yesterday including Windows 7 and a Nvidia graphics card. Since then the PC has been been playing up with the mouse pointer becoming jerky, the CPU indicator running at 100% with indications of a lot of writing to the HD. The screen then blanks with "no video". If I wait a couple of minutes the screen comes back.
Is anyone else having problems with W7 updates, if not it might be the video card update (the card is getting a little old, 4 years).
