Hello Guy's
I went back to my sister House with my Laptop and connected her monitor to my Laptop and did the same thing to me "no system input" after XP try to load and then went back to restart and doing the same thing over again.
I also try another monitor on Her computer and it did the same thing!
so what else can I chek?
It is not the monitor problem, buddy. If you were able to see Bios screen, most likely it is the software problem somehow related to the onboard video device.
If the computer doesn't have any warranty on it (make sure you ask her), open it and take remove the hard drive in her computer and connect it to your desktop computer as a secondary drive, so you can get in there and back up her stuffs (pictures, songs, documents) so she won't lose them when you perform the next step.
After that connect her hard drive back to her computer and run the System Recovery Discs to restore her system back to the way it was when she first bought it.
Those System Recovery Discs should came in the box when she bought her computer. If she doesn't have it, you guys can use the Windows Operating System disc to reinstall it if you want.
Let me know if you have any questions regarding those above infos.
