HP notebook XP system scroll bar crashed in the past

Computer shop news HP notebook XP system scroll bar in the past is not the screen to gray screen and then come out the mouse, but the mouse does not come out of the gray screen does not move after restart 2 times to 4 times will enter the system and enter the system one Will all crash, go to the after-sales test and say system problems. I came back to the partition and reinstall the system. The problem is still just finished the system. I have put this problem in a day. What should I do? User analysis and answer: 1. This problem is not difficult. If you know, you can turn off the hard disk protection in the BIOS. Then use a USB flash drive to install the system. Try to download the system in HP's forum as much as possible, because those are tailor-made. If you can't talk, try not to unpack the driver. According to your question, 80% is not a hardware problem. 2. Do not use the G version of the system to install, use the installed version, drive with the original driver. If you can't do it again, if you can't do it, just explain it to the seller. 3. Restore the BIOS. No problem with the system image is a hardware problem. Looking for the software to detect the hard disk may be a problem with the hard disk. HDtune can. If you don't get the after-sales and let them help you, the fault will be repeated.
