double trouble in one row

Hallo vista lovers and expert,

I have two problems in a row of update.

yesterday I updated IE8 to IE9 and also graphic card driver (from windows update). My graphic card is Nvidia GeForce 8400M GS.
I am using DELL XPS M1330 and using windows Vista Home Premium x32.

here are the problems :
1. when I log in with my username, the explorer.exe is not loaded (the desktop is blank and not loading at all).
to make it work, I have to press alt+control+del and new tast and type explorer.exe to make it load the desktop.

2. i can not view the pictures with windows photo gallary. The picture can be open but can not see any picture. so I install and reinstall it and not working.
I can open the picture with photoshop but the picture seems to be not appear.

I updated my graphic driver to the latest one but it is still the same.

can anyone help me please?

thank you a lot

Welcome, lets see if a simple system restore works.
Go back a few days before the problem, began. YOu will lose IE9 and IE8 will replace it. Any other changes will be, in like fashion, be replaced.

my fault I turned off the system restore to save space

i will try the clean bot How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7
and will update here...

thank for the prompt reply

If clean boot does not work try in safe mode, will help us diagnose if nothing else.
Make a full anti virus scan download and make a full scan with malwarebytes. Dont let the possible conincidence of intalling IE9, confuse us, anything is possible.
