Black screen when booting up windows 7 with any usb attached

[bisharat]

Hey, I got a really weird problem here. So here's what happened: MY old Acer Aspire T660 desktop pc has 1 GB RAM (767 is actually usable), basically it was preinstalled with Windows XP Media Center Edition, and so this PC was also compatible with Windows Vista, provided I upgraded it. I did that multiple times and then had to revert back to Win XP due to performance issues (I know it is too obvious that Win Vista has a lotta problems). Now my parents are thinking of throwing this PC, so I installed Windows 7 Home Premium in this PC via usb, cuz I thought that if this one is compatible with Vista, then 7 shouldn't have any problems right? Everything is working well, except that if I startup my computer without any usb drive attached, it doesn't boot (won't show "starting windows" sign, just a blinking cursor), I attach my blue Kingston USB, and the PC boots up without any hassle. Any fix for this? I'm thinking that I have to increase my RAM from 1 GB to 2 GB, cuz I think the PC is trying to get more memory from other USB drives. ANY FIX FOR THIS?

Do you have a legitmate copy of Windows7?

Also, it sounds like your Windows XP may be too old to support Win7, or Vista without the proper upgrades they both require.

Well I never upgraded it, I've done a clean install of Windows 7. No, the copy is not that legitimate.

We don't deal with not so legitimate operating system or anything else not legitimate.
