No CMOS Beep, Onscreen image, working monitor

Hello,

I realy need some help here, I was playing Silkroad Online with a friend for the laughs and then all of a sudden my pc decides to crash, screen turned off as if it wasnt connected and I could here his voice repeating (using ventrilo).... I restarted my pc maunally (pressed power button) then it started up to what seemed to be fine exept instead of the usual BIOS single beep it was replaced with a long beep, which my brother thought sounded like 3 beeps realy quickly.... The screen is still doing the same thing by pretending nothing is connected, I have checked the monitor and it works like a charm as it is currently plugged into this laptop and working fine.

I read some forums and heard about the RAM so I took the RAM out and put it back in, same with the GFX Card and HD... I also took the onboard CMOS battery out of the mobo and then put it back in

Now when I start the computer, it is the same as before yet there is no BIOS beep at all! This is realy frustrating me as I only recently built the pc (3 weeks ago) and it was my first build

I realy dont want to replace anything as I spent alot of cash for the bits although if I have to I guess I have to =[

Specs....
AMD 64 X2 2.6Ghz Dual Core
2GB DDR2 RAM
250GB HD
Gigabyte GA-M57 SLI-S4 mobo
nVidia Geforce 7900GS
450W Power Supply

If you have any sugestions or even better, a solution I would greatly appreciate it as I REALY need to use my computer for work and, this sounds sad.... Its pretty much everything to me, as I dont do much else apart from getting home and going on the computer


Please get back to me A.S.A.P
