If your computer runs from the hard disk then the disk is probably fine. Don't send the PC into HP, you "have a 5 yr warranty at the store you bought it from.", take it there. If they can't fix it then it's their responsibility to send it out on their dime. Ask them what procedures/protocols do they follow to diagnose/ repair systems under warranty. You should also read the warranty as well so you know what is expected of them.
Some things that you can do:
1. uninstall any third party firewalls or turn off windows firewall if thats what your using. reboot
2.Take a look at this HP website and follow directions to get restore to work or do a full system recovery.
3. Run Disk Clean UP. See
In the Disk Cleanup Options
check all files
In the Disk Cleanup: Drive Selection
select drive usually "C"
In the Disk Clean up tab
select everything except
"compress old files" if shown
In the More Options tab:Programs and Features
uninstall any programs that you don't use.
4.Run System File Checker. For more info go here:
5. Run Checkdisk .
6. It's very likely that virii or spyware is causing the problem.
Download and run SuperAntiSpyware free edition here:
and Malwarebytes Anti-malware
It say $25 but that's if you want to buy the real time protection using it as an on demand scanner is free.
If any of the above freeze reboot the PC (alt-ctrl-del) or hold the power button down for 5 seconds.
