I am having troubles updating my drivers I am using an Nvidia Geforce 8800 GTS and when I install the latest driver 8250 it gives me an error that it failed to initiate so windows stopped it ( code 43 ). In addition to that when I start up my computer before the log in screen there are about 6 vertical blue lines which weren't there before I recently reformatted my computer. As well as those problems sometimes when I try to open a window it will sit there for a bit and then just not open the window such as windows update or control panel.
thanks in advance
