Help! New built comp has no video input.

Recently built my fourth computer, all of them has started at the first try with no problems but this time when i start it there is no video input, I've tried the card before at my frieds place and it worked fine. My specs:

Motherboard: Gigabyte MA770-UD3

GPU: ATi Radeo Powercoler 4870 1 gb

RAM: 4 gb g skill

CPU: AMD Phenom ii X3 720

PSU: ATX 630

Ive connected both 6 pin PCI...

HELP!

Have you tried any other cards with your PC?

I have not tried any other card on this comp.. the fan starts on the graphics card but nothing else happens..

Possible problems: dead PCI-whatever slot, does the motherboard have another one? Do you have a second card to test it out with?

Another problem, motherboard in general having some issues. Maybe you need to update the bios or install drivers?

Ill try with my 8600 and see what happens :|

Maybe the motherboard is DOA... newegg's user reviews of that board are filled with that problem.... And, Umm... I don't see any listing for Phenom 2 on the newegg description. http://www.newegg.com/Product/Product.aspx?Item=N82E16813128376&nm_mc=KNC-YahooSSP&cm_mmc=KNC-YahooSSP-_-Motherboards+-+AMD-_-GIGABYTE-_-13128376 Maybe, Phenom 2's aren't compatible with that motherboard out of the box?

Although.... the CPU chart does your Phenom II's listed as of a F5 bios http://www.gigabyte-usa.com/Support/Motherboard/CPUSupport_Model.aspx?ProductID=2978 Maybe it needs a bios update before it will work with a Phenom II? Problem is, how do you update the bios if the CPU won't let you....

Most likely it's my first guess, though... board is DOA.

The motherboard supports the latest phenom ii and am3 100 % positive. Ive tried the card on my other comp and it works, tried my 8600 on this comp and it didnt work. So its the motherboard then... Any idea how i solve this?

AWw I bought it on ncix when i was on vacation in vancover and now im back in sweden.. :cry: guess its better to buy it local here even though it costs ten times more..

Okej thanks for the help :)

Threesixtyci was correct, according to GIGABYTE it is the BIOS that are out of date for my CPU to work.. But how does this effect the GPU? And will it be possible to update my bios without seeing what happening on the screen and with some luck?? I do not have a floppydisk though.

Umm... that was kinda what I meant when I said: "Problem is, how do you update the bios if the CPU won't let you...."

See you're not seeing anything on the monitor because the CPU isn't posting.... Without the CPU working, nothing works. That includes your video card.... See, you gota chicken or the egg, scenero. Most often this problem doesn't happen. Most often the motherboard will use a default underclock setting that will allow a Higher speed CPU's to still post and thus will allow you to update the bios or to manual set the correct mhz and multiplier. What you have is a CPU that doesn't want to work at that lower clockspeed that the motherboard is defaulted to. So... about the only thing you can do is get yourself a CPU that is compatible with the bios... Update the bios, and then you can plug in that Phenom II CPU, and be on your merry way. I just figured that the board was DOA..... because more often than not... the CPU will underclock and post. Which will then allow you to update the bios and get you to that official higher clock speed.

Your best bet, if you haven't done it already... is to either take it to a computer repair shop and have them update the bios. (What they will do is use an older CPU). Or you can spend about 40 bucks for a bottom end CPU, and try it yourself... But if that Board is DOA then it's all for nothing.

Probably the first thing you should do is tell that motherboard company that you got in contact with. And tell themthat the CPU won't post; which means that it's impossible to update tothe compatible bios. And see what response they give you. If the motherboard is known for that... then the optionsin my previous paragraph may be the best things to try. (heh... probably cost the same, too...)

Porblem is solved now :) I bought a cheap cpu that worked with the old BIOS and installed the new ones and then installed the better cpu.
Thank for the help everyone
