Why does Internet Explorer fail to display a verynarrow and specific set of webpages on ESPN website

I have two symptoms of a problem: On my desktop PC, I can get into the ESPN website, log-in, go to various pages, but cannot access my Fantasy Sports Team pages on this computer, I get the error message mentioned above.  My laptop works fine, side by side, so the problem is internal to my desktop PC.  Second symptom:  System restore will not restore to any of the listed possible restore dates.  I've tried many fixes, off many websites, to no effect.

Have you scanned for malware lately? Download, install, and run SuperAntiSpyware:

You can also try resetting you browser to defaults. Right-click on IE desktop icon and choose properties. First, delete all temporary internet files and cookies. Then, select the advanced tab and press the Reset button on the bottom right.

What is the error you receive when you try to do a restore? Is it a permissions thing, or an error? Maybe try system file checker:
Start --> Run --> cmd <enter>

Scanned using Spybot today -- first time with that product, previously used Xsoftspy or whatever daily. Ran sfc -- it hung up about 98% in, and asked for "XP Professional Disk CD2" -- my Dell pc came only with restore disk, wouldn't recognize the cd.  I'm downloading your "superanti-spyware" now and will run it.
That is strange that it is asking for CD2. I know that it asks for the XP disk, but never had it ask me for CD2 before. I have retail XP Pro and don't have a CD2 lol.
10 Tips to Protect Your Business from Ransomware

Did you know that ransomware is the most widespread, destructive malware in the world today? It accounts for 39% of all security breaches, with ransomware gangsters projected to make $11.5B in profits from online extortion by 2019.

Realize its been a long time since your earlier advice.  Your Superspyware took 3.5 hrs to do a complete scan, and it found a lot of junk (as they all do).  But after quarantining and rebooting, nothing has changed.  Had also previously reset all internet settings to default.  This is a real mystery.  The ESPN site worked until a week ago, then stopped letting me see my fantasy team.  The adjacent laptop in a docking station (my work machine, as opposed to personal) works fine.
lol is right, I guess.

Tried everything I can think of.
I can access this url (and almost all others) and I can login:  http://games.espn.go.com/frontpage/basketball
But I can't access this URL and a few related ones:
I get this message:  "Internet Explorer cannot display the webpage"
I've tried all of the obvious routines like deleting temp files, web history, cookies, I've run three spyware programs, and I have McAfee running all of the time.  I could use some new ideas.

I re-posted the question more simply, and received an effective although partial solution:
I installed Firefox and was able to access the website from that browser.  However, IE7 still did not work on the problem url, so the solution is an effective work-around, but did not find the root cause.
