This started when the screen saver came on. The PC would lock and the screen would be covered in tiny green wavy lines, breaking up the main image. It also happened in flight sims so I put it down to the video card. I disabled the screen saver and stopped playing BoB Wings of Victory. I downloaded the latest video drivers and installed the latest version of Direct X but it seems to be making things worse!
Now it crashes in
any application, with no apparent trigger. All my Norton AV stuff is up to date. Here's my specs:
Dell Vostro 410DT, MS Vista Home Premium
24” monitor
Intel Core 2 Quad Q9300 Processor (2.50GHz, 1333 MHz, 6MB cache)
3072MB 800MHz Dual Channel DDR2 SDRAM (2x1024 + 2x512) memory
500GB hard drive with 16MB cache
512MB nVidia GeForce 8800GT graphics
MS Force Feedback 2 joystick
(......
and don’t ask me what any of that means!!)
Help!
