Windows 7 is giving me a real pain the past couple of weeks. Couple of BSOD's, and now it says my NVidea drivers are corrupted, and the screen just turned black, and some programs (like all windows live programs) have got big black lines across the screen, and I'm unable to close them. Also, my internet connection sometimes just switches off on W7, and I have to disconnect my router and modem. It's usually when messenger, WL mail and a lot of other internet stuff are open at the same time. I think it's W7, because the XP computer upstairs, which is on the same network, can still access the internet, and both of our W7 computers can't. Any help is appreciated. Updating drivers isn't possible at this time, because I haven't got access to the admin account.
