Hi everybody, hope you are all well. Deep breath, here goes. When my computer starts up and eventually gets me to the sign-on screen, when I do this, my screen goes black a few times, but eventually displays my desktop. When I want to play a game, i.e. "Warblade" it goes black a couple of times, and then displays the game ok. Someone, who knows more than me, says this is a graphics situation. Is this correct, am I worrying unnecessarily? My specs are:- Asus P4R800-V deluxe mobo, 1GB ddr ram, Invidia FX 5200 AGP 256mb, DVD re-writer, 450 PSU. Thanks to anyone who can reassure me, please note the m/c does not crash and the display is fine.
