This system is put together with an older HD that is working. When I turn on the power I get light, fans but bios will not load and I get no cpu beeps. Have returned and replaced the mobo, cpu, vid card, power supply and ram. Tried different case and monitor. HD works in another pc. I am completely stumped. Thought for sure it was the mobo but just got a new one in and its still doing the same thing. Get nothing on the monitor, no signal. Have used different cables to the monitor as well. According to Gigabyte, everything is compatible. Any more ideas?

Added- From Gigabyte support "Athlon II X2 250 is supported on this board, but if current mother board bios is F1 only that need to update bios to F3 support processor." Does this make sense to anyone?

Just in case, did you plug in the 8 pin CPU power supply connector to the motherboard?

I would think that means you need to update your BIOS.

Yes, the cpu power supply connector is plugged in. How do I update bios if I can't boot into bios?

thank you

You'll need to get hold of an older processor that's supported on your mobo.

I had the exact same problem the first time I tried to turn on my Gigabyte processor, but then I used the converter that came with my video card, to turn it into a vga port, and plugged the monitor directly into my video card and everything working fine now. Hope this helps. BTW my video card is an Palit 4850 GDDR3 512mb.

Yes what he said...

I think his compatibility is fine as my mobo works fine with the Regor 245, unless mine has better compatibility?

It does indeed have better compatibility.

As I mentioned, this means his board doesn't have the proper BIOS. If you don't or can't get a hold of another processor, you can just return or exchange the motherboard, the newer ones likely have the latest. No guaranties though.

BTW, how exactly is this relevant?

I had this problem for awhile or something like it but all i had to do was reset the bios.
