Roll back to the earlier version. Delete IE9 reboot and the system should roll back to the earlier version. Similar issues have happened to others with the upgrade, it is an MS thing and if you ask them (MS) you will get more of a headache than you had fighting with the glitch.Then, at some point in time (when you feel brave enough) try doing the upgrade again, of course there is always good old MOZILLA, which just seems to roll on. Best of luck!!!
I am troubleshooting a friend's eMachine laptop. It has a 2 GHz dual core CPU with 3 GB of RAM running 64 bit Windows 7.
He complained that IE 7 began running very slow all of a sudden. A virus scan was run but returned 0 problems. I checked device manager; no problems. The PC includes an Atheros Ethernet NIC and Broadcom 802.11g wireless.
I upgraded to IE9, but the slow performance continued. I noticed the performance of the entire PC slowed down while IE continued to load. Once the page finished loading, everything worked fine. Out of curiosity, I installed Firefox to see whether the problem was isolated to IE or to the whole NIC. Firefox worked like a charm loading right up. My friend would have been satisfied with the workaround, but the web-based software he uses for work is only compatible with IE.
I would be greatly indebted to whomever can help.
