Hello,
Thank you for posting in the HP Support forum.
While it is very difficult to troubleshoot such issues without specific clue on a forum, I would suggest the following:
- If your HP computer came with Windows preinstalled, then I would suggest you try to back up your files on external media and them perform HP System Recovery. This will restore your Windows to factory default condition. Here are instructions:
Windows 7: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01867418&cc=bg&dlc=en&lc=en
Windows 8: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c03489643&cc=bg&dlc=en&lc=en
- If your HP computer did not come with Windows preinstalled but you installed the operating system post-purchase, then I would recommend you back up your files and reinstall Windows. Do not forget to visit the HP site to get the latest drivers for your computer as you will need them afterwards.
Please, let me know if something is not clear and don't hesitate to ask for help if you face issues.
