I have a HP Compaq d22 MT desktop. I can't seem to install Win XP Pro SP3. I am no noob to computers. I have taken a USB flash drive, made it bootable, put Win XP pro sp3 on it. Used this USB flash drive to install the OS on another computer just to make sure it works and it does! But on my HP it will not install. I have deleted all partitions on a 80 GB hard drive, created a new partition, formatted it NTSF. The files transfer from the USB Flash drive and it starts to install but when it gets to the " starting windows" part in just goes to a blue screen and tells me the death words " windows is shutting down to prevent damage to the operating system " With nothing on the formatted hard drive it can't be a virus or anything and there is no OS to damage yet so I am confused?? I have changed the bios to boot from USB so that's not the problem. I have removed all other hard ware and set bios to " no 3 1/2 floppy ", set the current date, time etc! Any help would be appreciated. Oh I have tired this with 3 different hard drives I have laying around and it does not work, no errors on hard drives, or bad sectors etc. I can only guess its some kind of HP thing?? I do have a computer with Yahoo Messenger to chat live if you think you can help or point me in the right direction. This is posted on October 14th 2014
