New PC won't boot

Bios file 0707 is required for the 6100 cpu. You may need to flash the bios with an older am3 cpu. It's too bad the board makers don't put a label on the box showing you which bios version is installed on the board. It could also be an unseated stick of ram or any number of issues. I would search youtube for troubleshooting videos or this website for faqs.

isn't there any other way to flash the bios file? i havn't got any other AM3 proc lying around  
other strange thing is:

1. tried the both sticks of ram seperate in every slot, no change.
2. old motherboard (asus P5n-e SLI) with old proc (Q6600) shows same problem with the new VGA.
other tests:
old mobo old proc old vga --> works
old mobo old proc new vga --> doesn't work
new mobo new proc old vga --> doesn't work
new mobo new proc new vga --> doesn't work
new mobo new proc onboard vga --> doesn't work
new mobo new proc 1 stick o'ram --> doesn't work

could it be my proc is broken?
could it be my mobo is broken?
could it be both ram sticks are broken?
could it be a broken external vga?

All I can say is I would return the board or the cpu to the vender. Some of the older boards have been on the shelf for awhile, so the newer bulldozer core cpus won't post with the wrong bios file. You can get a sempron 140 used for about $25 to flash or pay shipping either to the vender or the manufacturer and let them deal with it. Sorry for your inconvenience.

ok, i'il contact the vendor.
but then, the new VGA on my old system shows the same error, is that VGA broken or does my screen philips SW220 something, save anything about a vga of some sort?
because the new VGA with the old system doesn't work aswell

Maybe you're using a bad power supply connection. I'll assume you've got the ps lead going to your 6950 video card. If you're trying to use an older power supply for testing, it may not work with your new card. But I'm still betting on the bios flash or operator error somewhere.

contacted the vendor, they told me to flash the bios.
why the VGA didn't work:
the old motherboard (asus p5n-e SLI) doesn't work well (read: doesn't at all) work with radeon 5xxx and above.

going to flash the bios now.

tried flashing the motherboard with an other processor, turns out the other processor was an AM2 socket 1. now i have to wait until saturday to get it flashed at the store.
