I can get display no i found that problem out i had the ram in the Dimm_A1 when it was supposed to be in Dimm_B2 i entered the bios and since im trying to use a hard drive with the existing os from my previous computer i have downloaded the vista repair disc put it on a flash drive as well as the BIOS update from the asus website for the p5e3 pro mother board and when i go into the bios i set the boot settings to removeable disc the my HDD then the cdrom then i save and exit bios and the computer reboots and i wont get a display til i go back in and clear the RTC then i move the jumper back i start the computer up no display i hit the reset button on my case its shuts off comes back on 1 beed from the speaker and then i got display not sure why it wont boot from the flash drive or what is going on but everything seems to work but the loading of the os . i dont have a disc and dont want to have to buy the os disc. and i havent powered my cdrom to the psu due to waiting on another cord to come in the mail for my psu.

If anyone could help it would be greatly appreciated
