I am building a new computer. I have a Gigabyte MA790GP-DS4H motherboard with a Phenom Am2 quad core processor with 8 gigs of ram 2x4 sticks and a GeForce 9600GT video card and 2 SATA hard drives 1 300 gig and 1 250 gig all in an Antec case. The problem. I installed windows xp on th eone hard drive but now it freezes up and my keyboard stops working. I tried install Vista on the other hard drive and ended up having the same problem. I build computers on the side and have never had a problem loading any windows program and have never had a problem building duel boot computers. I was looking in other forums and ran across uping my ram from 1.8 to 2.1 which I did and I also saw a couple of forums that mentioned to load os in AHCI. Since changing the ram to 2.1 I cannot get the motherboard to boot up at all. Any suggestions on how to fix the problem? I usually figure these things out but this one has me stumped
Try installing with only 2G of RAM. If it's XP SP1, there are issues installing w/ more than 3G of RAM. You can download SP2 and then install the rest of the RAM.
I have seen that happen on older MB, Deselecting the Halt on all Errors or USB legacy
support was the issue back then. Those are typically not choices any longer with newer Bios ver. Upping the ram causes more problems than fixes in this case, wait till
all is well before overclocking.
It could be a Ram issue, most definably not HD issue as you have ruled that out.
The windows xp I have is with sp2 and when installed I up it to sp3. I do this with all fresh installs. I will try using only 2 gigs of ram to see if that helps.
If the disk is SP2, it's probably not the RAM issue I mentioned above. Although booting with only one stick is a good way to start narrowing it down. You also should unplug everything except the HD, video card, and the 1 stick of RAM.
