both my hdd and dvd drive show up in the bios, and when I set the dvd drive to first in the boot order and put in the vista disc it just says "booting disc: _ " and then it says some error that it cant boot and please insert a system disc. I also tried an xp cd I know works, and same problem so I dont think its the copy of vista.

any help is much appreciated

Go into BIOS and set the memory voltage to "+.20" (the Gigabyte default is 1.8v and your RAM requires 2- 2.1v).

didnt do the trick, still says "boot from cd/dvd" and doesnt go anywhere from there

the samsung drive you are using is extremely gay about what media it will boot from. i have the same drive and, honestly, it doesnt boot from any. i just use another drive for that. try a different optical drive

other things you may want to check....

is the vista disc a BOOTABLE iso?
disable hdd entirely from the boot order....make cdrom or dvdrom or whatever the choice for all 3 boot devices

i think it has some thing 2 do w ur cmos settings.

Which set of SATA ports is your DVD hooked to?

Try putting it through the purple Gigabyte controlled ports instead of the ICH9R ports.
In BIOS, make sure the Gigabyte controller is set to "IDE" mode.

and after setting back hardware settings go to mobo settings and set as default.

ok, It booted. but now in the bios it says my ram is running at 800 MHz, shouldnt that be faster? and in cpu-z it says 400MHz under each stick. I read something about updating the bios to fix this, should I update because I heard its risky? and how do I do it

I have a GB board also and the DVD that came with it has an application called @bios that will do it for you, or you can get it from the Gigabyte page for your model posted above. I mean I guess it's risky but as long as you follow the instructions to the T and don't shut your computer off while it's working I don't think you would have any problem. I have updated bios on many different boards and have never had any problem with it. I would however recomend using the DVD that came with your MoBo.

I don't know if this would fix the issue though it's worth a try. Good luck and tell us what happens.

I got the bios updated to the latest. but it still says memory frequency: 800MHz in the bios and says Memory speed: 400 MHz in cpu-z. I checked and all the memory timings are what the factory recommends. thanks for the help.
