My desktop pc will not boot up. It runs through the boot sequence, ten gets to the windos logo then screen goes blank. I have tried to press F8 which get me to several options ie. safeboot but the thing just hangs and I cannot use the arrow KEYS to select an option. Any help WOULD be really appreciated.

OS is vistaWhat happened prior to this ?
Have you tries a PS2 (old style round plug ) keyboard ?
Do you have a Vista DVD ?If you cant get it WORKING try formating the hard drive and re-installing vista. Or try using a restore disk if you have one or the repair feature if you have an actual copy of vista.thanks patio

i have a logitech keyboard, not the Ps2 sort, its infa red i think. i also ave the vista disk as well as the old xp disc. i am not sure what happened previous to this as my wife told me it wasnt working

I cant format the disc as i cant get to any command prompts

any clues?

daveIf you format you will lose all your info...
Vista Repair Install
You may need to borrow or buy a PS2 keyboard...everyone should have one for emergencies like this.
Or you COULD check to see if Legacy USB devices are enabled in the BIOS.
