Process Validation errors after clean intallation of Win 7

hello

i clean installed new WINDOWS 7 PROFESSIONAL 32bit on laptop SONY VAIO VGN-FZ11Z. Operating system is genuine but downloaded from MSDN.

But it is giving me a lot of process validation errors. Genrally these errors are coming on application launch. After that mostly application aborts or restarts. Any help in this regard will highly appreciated. you can visit the link below of my other thread where i have already posted some snaps of these errors.

Why did you start a second thread while the first one is active?

no problem is coming on start of first event. e.g

1- when i try to launch windows live mail it almost crashes every time on its first launch with such errors.
2- when i press ctrl+B or ctrl+H in internet explorer, it also gives same error
3- and some times when i launch a software set up file but rarely
