sony vaio drivers problems after format  

hallo everyone. Recently,I formatted my sony vaio VGN-FW51MF and now i have windows 7 professional, downloaded from msdn. since then i face several problems and I wonder what went wrong. So, to start with:

Everytime i run internet explorer, an error message saying that iexplorerencountered valid error appears and gives me the option to ignore once, always or do not ignore. if i choose not to ignore, the problem is not solved.
Kind of the same message, saying "HD audio control panel encountered a validation error" appears usually, as well.
In addition, when i try to download utorrent, i get a message saying that "utorrent has crashed. unable to generate crash dump", and the download stops.
I wonder if i ve done sth wrong with the drivers i installed, since i m not pretty sure what i need to install.
Thank you in advance
P.S. : i am a newbie so please use as simple language as possible..

daffgr, welcome to the Seven Forums.

Did you remember to install all necessary drivers, or is it just running on whatever drivers Windows installed for it? If you didn't install any drivers go here,

Sony : VAIO VGN-FW51MF/H drivers | Download drivers and updates for VGN-FW51MF/H

to get them. Sony has the full range of Windows 64 bit drivers. In order of importance the ones you need are,

chipset
graphics
ethernet
audio (bottom of the list, only need the HDMI driver if using that connection)

This way,

Driver Install - Device Manager

i face kind of the same message saying that "the WINDOWS EXPLORER encountered a vaidation error" appears every time i try to open the control panel.it seems like i have downloaded all the drivers just fine. Is there any possibility the ISO downloaded from MSDN having some problems?

From having a quick look around,

WINDOWS EXPLORER encountered a vaidation error - Google Search

it is certainly possible that there is something wrong with the download, or that it got corrupted some how after downloading.

Recommend uninstalling and then installing IE9 How do I install or uninstall Internet Explorer 9? Note: You may want to download the installation file for IE9 before uninstalling it so you have a way to install it again (since you may not have a working browser to download it afterward). Save the IE9 installer to a safe place you will remember for installing after you uninstall the program.

Also, run SFC /SCANNOW Command - System File Checker as it seems you may have some corrupted system files, though it may also just be that IE9 is interfacing with the system files incorrectly and the above step of re-installing IE9 will fix the issues.
