Anne,
Just my personal 2 cents worth:
You have been covering some serious techy ground in this thread ...just because the experience index doesn't work (?).
An In-Place Upgrade is going to cost $$$.
If the only problem your having is being unable to run the experience index, just ignore it if your computer works OK.
The experience index just gives you a score of "how good is your computer?". A bit like a 1-10 on personal looks. You don't need it to keep living.
If you want to worry about a computer issue, wait until you get one a little more serious than a bit of W7 bloatware not working.
Don't download or run registry cleaners or computer optimizers. They are dangerous snake-oil. I notice you have deleted one of these program. It might have been responsible for the problem with chkdsk and/or the experience index.
A better performance view that contains plenty for you to a degree and plenty for a tech to notice problem areas is:
PCPitstop's OverDrive test
This test is fast, Comprehensive and Free. I've used it many times to help with computer issues.
In just a few minutes, the OverDrive test creates an extensive report of your PC's performance, security, software, drivers, and more. In order to receive the full benefit and display the full Results of OverDrive, use Internet Explorer.
Note: Vista/Windows 7 users with UAC must first Right-click IE - Select "Run as Administrator"
- Close all instances of Internet Explorer and any other open programs.
- Click on W7 Start
- Right-Click on Internet Explorer and choose "Run as Administrator"
This will give your machine full privilege to take advantage of all the features of the PCPitstop's OverDrive full test.
- Navigate to PC Pitstop's Overdrive **http://www.pcpitstop.com/betapit/** using Internet Explorer and click on "Create free account".
- Register and accept the necessary active-X needed to run "Overdrive".
- Run PC Pitstop Overdrive.
- Post the URL link here from the address bar which will allow techs to view your results. No personal information or serial numbers etc. will be shown. You and your PC remain anonymous.
Caution: During the testing of your PCs Video Adapter, a variety of patterns, shapes, colors and text are “flashed” onto the users monitor screen. In the many thousands of daily uses of the PCPitstop full test over several years, two individuals
who suffer epilepsy experienced discomfort and temporary dizziness when viewing the flashing patterns. If you know that you are susceptible to photo driven seizure, please look away from your screen during the Video Adapter testing sequence.
Note: PCPitstop is a free service, but like many free services and programs, it is supported by various paid products and I do not support their use.
This is a very common test used by techs in Tech forums of high esteem (Microsoft MVP holders).
