Hello, recently I've had an error on my laptop that effectively makes it useless unless I use it in safe mode.
My laptop will load properly and reach the Vista login screen fine, but after I type in my password I get the error: 'Dwm.exe failed to initialise (0xc0000022) and if I click OK another error pops up saying that explorer also fails. Then my screen is blacked out, and feeble attempts at trying to access task manager provides: taskmgr.exe failed to initialise properly.
I've been told to do a system restore, but for whatever reason I don;t have any restore points although I'm pretty sure I used to have several.
Please help, you will literally make my year! Thanks.
P.S I'm using Windows Vista Home Premium.

If you can boot into Safe mode only, that is usually an indication of a bad driver.

My first suggestion would be to replace the Video driver.
Recommend you first download/install/run Driver Sweeper ...
to remove the Video driver.
Reboot to see if you can now boot up normally.

If you can, then recommend downloading a new Video driver from the video card's manufacturer.
