Dear People

I have a Asrock P43 twins 1600 motherboard. It has been doing a few funny things, keep resetting the video driver 512 Geforce and have tried another card but it comes up with pink pixels on screen, would not let you play solitare, keyboard won't work and keeps black screening when you go on the net. I thought it may be video drivers so downloaded the most recent from geforce but that didn't work as it still kept freezing and saying the video driver has recovered from driver error.

What do you think
