I assume you are trying to install windows on to the unit? I'm thinking that, if you're making the USB key on a Mac that the PC doesn't like it.

This site has an excellent step-by-step guide for making a bootable USB key using a Microsoft tool. It's pretty fool proof.

that's my only option at the monemt  i have done it before and it worked fine...now it wont work at all...i also noticed one of the fans near the pci slot does not spin at all...also thanks for your respond...it simply refuses to boot via the usb,the internal hhd,it keeps saying something wrong the boot drive,also initiallythe boot drive was working fine then it just stopped booting which brings me to this situation...im thinking there's something in the bios that im overlooking
