I have an HP Pavilion Media Center m7590n it has been upgraded to Windows 7 . There are sites I can no longer use as they hang and the page says explorer has to restart.The guy who did the install said nothing I can do the hard drive is old and some sites will not work and to use till it goes and start saving for new comp ..Was he suppose to get drivers from Hp . He did not use hps site when he did the install. I do not think he did the upgrade right. Now for me my hp is no longer usable for my needs.
What and how do I fix it .Please help.
