Asus G50Vt-X5 wont boot win 7 beeps rapidly

So my computer was running fine until i turned it off. then later when i turned it back on it whent through the computers boot logo(not part of any os, will do this even without a hard drive installed) then it loaded what looked like command prompt in full screen with the blinking white "_" cursor then the cursor moved down as if someone hit enter and it starts beeping rapidly non stop. The beeps are all the same ( ive heard of beep codes and ive heard them and this isnt it) it beeps forever until i turn it off. Also on a different hard drive in the same computer i have vista installed and that works perfectly. But back to the windows 7, i tried it with one ram (one of each) and without any both rams are fine because i did the same with the rams while trying to boot into vista and vista booted every time. There fore this leads me to believe that the hard drive is causing this problem so maybe something is wrong with the windows 7 hard drive/partition. All help is appreciated.

Thanks.

i dont have the cds my version is still rc. Forgot to mention that i had that i believe my last action on windows 7 was uninstalling the kb971033 update or whatever one is the WAT update. That was my reason for restarting.

Time to purchase and install Win 7 RTM.
