Solved all sorts of .exe files are not working

[demonoic]

hi. i've got this problem with my laptop which any .exe files are not running. Double-clicked and nothing happened, right-click and there's no "open with..", on properties there's no "change..". Try to do a restore first coz i thought running the cd would be best, but then got this error: C:\Windows\system32\systempropertiesprotection.exe "No such interface supported".
I mean, all .exe files cannot be running. I cannot even uninstall most of the programs. I dont know what else to do. Here's some details:

amd turion (tm) 64 x2 mobile technology tl-60 2.00 ghzz
2.5 gb ram
64-bit OS
windows 7 ultimate

hi there run this file check

Perform a SFC Scan (System File Check)

1. Click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator. If you are prompted for an administrator password or for a confirmation, type the password, or click Allow

2. Type the following command, sfc /scannow and then press ENTER:

(A message will appear stating that 'The system scan will begin'. Be patient because the scan may take some time)

3. If any files require a replace SFC will replace them. You may be asked to insert your Windows 7 DVD for this process to continue

4. If everything is okay you should, after the scan, see the following message "Windows resource protection did not find any integrity violations"

5. After the scan has completed, close the command prompt window, restart the computer. (TIP repeat scan 3 times)
