By "System Restore", do you mean "System Recovery"? At least that's what HP calls it.
I had major problems with mine after I accidentally messed up the boot sector. I tried System Recovery and it wouldn't work. It had me pulling my hair out for a few days, until I got one of their phone technicians to ask me if I had changed my hardware configuration in any way.
I had. I added a CD burner, a hard drive, and my old keyboard.
She told me I must restore my system to original hardware configuration for the System Recovery to work.
After I did that, it worked like a charm.
It ticked me off that they don't include that indispensable little tidbit of info in their troubleshooting guide.
Hmm, that’s interesting. I don’t see a “System Recovery”. My HP titles it “System Restore”; where it supposedly will restore it back to some previous date. Well, it won’t.
If it’s restored to the original configuration, didn’t you lose everything you had on it? I really don’t want to do that and if the back up disks only work when they feel like it, well...
But, before you do a reinstall, run disk check to make sure there are no errors on the disk.
