Hey guys. I recently was installing a new video card, and I might've toggled with some of the BIOS settings that I shouldn't have, and now my computer won't boot at all, but sits on the first screen with the "Decompilation prohibited" logo, along with distorted graphics and what not. It won't go anywhere beyond that. My specs: HP Pavilion 504n 2.00Ghz Intel Celeron My mobo is a Phoenix/Trigem, according to what it had said before. I wish I could be more specific, but seeing as I can't do anything with that computer at the moment, that's all I know. Help! Also, if someone could help with my video card trouble. Now, if I don't have the card in, I get the above. if I DO put the card in, however, (GeForce FX 5200 PCI 256MB) It boots, but I can only see the mouse cursor on a black screen, and none of my keyboard commands work. If anyone could help me with either/both troubles, I would be very gracious, one gamer to another.
