i have an hp slimline that has a 6150 nforce integrated graphics card and i want to upgrade to an 8800 geforce. i removed the motherboard and mostly all of the guts into a larger case so i had more room to work with the graphics card, and i had to leave a system fan as i also upgraded my power supply. so every time i boot my computer it says something like system fan removed, and i cant make any changes to my bios without it defaulting. is it possible to upgrade it?
