Because of trouble getting a new videocard to work on my old computer i tried upgrading the bios, this solved the problem with the videocard

, but a new problem arised

. Each time I turn my computer off, and try to restart it, it won't start. When I try turning the computer on, I can hear the fans starting, and the Harddisks and CD-player, but the monitor is not turned on, and nothing more happens, the only thing I can do is to pull the plug. After doing this I try starting the computer again, and this time it works like a charm

, but next time I turn the computer off, I have to follow the same procedure to get it on again. Turn on, turn off and then turn it on.
I use a Abit BX-6 MOBO, with Award BIOS, and the Videocard in question is a 32 MB winfast geforce 256
Does anyone have a suggestion??
Hope you understand my english?
