[RESOLVED] ASP IE 6 & 7 issues

I'm a developer that works with ASP.NET and classic ASP, usually using IE 7.

Something has changed on my system and I cannot track it down. I haven't installed any new programs and I haven't changed my hardware, mainly because it's not my computer, but here are my problems:

All classic ASP VBScript and JavaScript no longer run on any web sites I'm working on, or any I've ever worked on and hosted in the past. That includes dozens of websites. It's as if I never wrote that code into and of the pages. Heck, even this page I'm using to write out this thread is broken - none of the buttons for emoticons or formatting work! They're not even hyperlinks anymore - just plain images. That literally changed one day, out of the blue.

ASP.NET pages give me post and validation errors that cannot be caught, and AJAX seems to keep "breaking" pages. They stop working and I have no idea why.

Flash works on maybe two sites, but almost every site on the Internet says I don't have flash even though I keep re-installing it. I'm using Design Premium CS3. So for instance, I can see flash in ads all over the web, and in Myspace, but everywhere else insists I don't have it.

Now, as of today, the browser can no longer redirect pages, and any AJAX has stopped working. For instance, on the Yahoo page, hovering over the tabs no longer makes them drop down, and I can no longer view my emails - the page is just plain text saying it couldn't redirect me. I obviously didn't change anything today - I just sat down at my desk.

I've uninstalled and re-installed IE 6 & 7. It seems the more I do that, the worse off the browser gets - at least last week I could click on the format buttons in VBForums. Now I can't.

Oh, and when I boot up, I keep getting this message: "DEP has shut down Com Surrogate", usually 20 - 25 times in a row. What the heck is this?

Windows & Microsoft Update are now just blank pages, so don't suggest that. Also, Microsoft.com is blank, and MSDN no longer searches.

Any ideas, people?

-EDIT-
I should point out ALL of this works fine in FireFox, Netscrape (haha), and Safari. This is an IE issue and because I am a .NET developer, I have to figure this out.

Vista or XP?

Windows XP Service Pack 2.

I've used the Automatic Updates to finally get all updates. No change.

It's gotten so bad now that nothing via IE works. I can't run my ASP.NET apps, I can't go to hotmail, yahoo mail, or pretty much any site. It's just dead. I've uninstalled and reinstalled, cleared my drive, repaired the installation, removed program after program, shut down everything at startup - I'm out of options. I guess a reformat is my only choice left.

DEP being Data Execution Prevention. I had a similar problem a while back when I installed the ffdshow codec pack, also on XP SP2; would that apply here?

Also check your DEP settings, usually set to the first option ("Turn on DEP for essential Windows programs and services only"). If it is, try swapping to the other option ("Turn on DEP for all programs and services except those I select:") and add C:\WINDOWS\system32\dllhost.exe to the list. You'll need to reboot for any changes to take effect.

Thanks for your reply.

Problem was just fixed.

Turns out that JScript (Windows Scripting), components were damaged. As usual, Microsoft has nothing online about it, or the effects of a damaged scripting engine. once I installed Windows Scripting 5.7 again from the website, everything works perfectly. Shocking!
