Unfortunately, the best advice I can give you is to use a computer that lets you get on the HP website and input the model number you have. All service manuals for your model should be downloadable via PDF.

A manual for your PC can be found here: http://h10032.www1.hp.com/ctg/Manual/c03694820.pdf
I'd suggest reading through the manual on recovery and troubleshooting sections.

Should be OK for you now if you were able to refresh the computer. Still let us know here if you're still having issues.
