IE8, Firefox, Opera hang maxing cpu; chrome works
by ccx508 - 11/12/11 5:29 PM
When I try to access any site in these browsers the task mgr shows them using over 90% cpu. IE shows "Waiting for ...", FF and Opera don't even show a frame.
Other services that try to access sites (e.g. sprtsvc.exe) also need to be manually killed because they peg the cpu at over 90%.
IE starts fine with no addons and a blank page, but attempts to access any site result in the same cpu hanging.
I have tried:
1. Resetting IE to default;
2. Full scans with AVG free, Kaspersky, MalwareBytes: nothing found.
3. Disabling all AV and firewall services.
4. Clean boot (only MS services started).
5. Uninstalling and reinstalling FF and Opera.
I don't think this is an IE problem because the other browsers do the same thing. I don't think it's a DNS or network issue because chrome works fine.
I've been screwing around with this for weeks and it's driving me nuts.
Any suggestions would be greatly appreciated.
