Im not sure if it's due to my graphics card but Im getting vertical streaks of dots on boot up on my desktop PC. This has only started to happen last night after I got home from work. The other problem is that sometimes the display would just go blank during windows startup (just after the windows startup logo disappears). Does anyone know what the problem could be, and how I might be able to fix it. Im a bit worried coz it's just over 12 months since I bought the card and has cost me an arm and a leg to get it.
