Presumably you didn't make a full backup image of the computer when everything was freshly installed and fully working?

Perhaps you have left system restore turned on though? That might enable you to go back to a point before these problems struck... certainly worth a try...

Tru running your IE without add ons. If it does not work try
Going to your C: drive>properties>tools>check now. If this does not help try
Using your Windows 7 DVD, perform and upgrade install.

OK,I'm new to this!! I'm an old guy that started w/3.11&dos6. I've just built this box and it's undoutably the biggest disappointment of all.64 bit Win 7 & 64 bit EI 8 isn't sure if it will be the default browser but it is at the moment.Tomorrow it may not open at all,or,it will look like a 1/2 built web page.It took a few tries to get here.What I'm leading up to??? I'm on top of a mountain with only dialup access and a fast box and this OS isn't very happy with me!!! Bad support system(drivers),troubleshooter hasn't a clue,EI 8 needed more optomizing and beleive it or not,cool edit pro(syntrillium version)works!!!It's music recording software that's 10 yrs. old!!!Has to be the most unpredictable systems I've installed.I've tried Crome and w/dialup it freaks!!firefox may or may not open as does EI 8. If any of you have to do dialup and have found a way that is reliable would you PLEASE!!!! let me know? Thanks!!!!! Ya'll
