Computer not displaying, no pc speaker

[sponge008]

So, my friend recently built a computer with these specs:

VGA XFX 7900GT 256MB PV-T71G-UDF
MB GIGABYTE GA-965P-DS3 P965 775
CPU INTEL|CORE 2 E6300 1.86G 775 R
MEM 512Mx2|PTR DII800 PDC21G6400LLK
160 gig hitachi sata
raidmax case with no PC speaker! CASE RAIDMAX|ATX-921WSP SIL/RED RT
PSU ROSEWILL RV450S-2 RETAIL

So, a mutual friend helped the first friend built the computer, I checked it out, everything looked fine. However, the computer does not send out any video signal on boot. Also, I checked the 7900GT in my own computer, and it works fine. The other problem is that there is no PC speaker in the case, and when I plugged in the pc-speaker cable of another case into the mobo of the non-working computer and turned them both on, there still was no beeping. The PC speaker of the second case WAS functional. This makes me think the motherboard is at fault. Does anyone have any other ideas? (for example, how to determine problem without another Core 2 Duo system, which does not exist in the circle of friends) Thanks.

I'd check the BIOS, but if your not getting a video signal, then you'd have to get an old PCI video card and see if you can get signal from that to at least look through your BIOS.

If the BIOS is dead, how would a PCI card help? (I'm not much of a hardware expert, just for basic building/upgrade/maintainence)

I wasn't saying if your BIOS is dead, I said you should look at the settings in the BIOS. But yes if indeed the BIOS is dead, ie your mobo is dead, then your screwed. end of story. But if the BIOS and mobo are good, try a PCI video card, maybe the BIOS doesn't have the correct settings enabled for your PCI-xpress slot, I don't know the defaults of that BIOS.

That would be odd, given that it's a brand new gaming mobo, but it's worth a try, if anyone can dig up a PCI vidcard...thanks for the help so far
