Vista - System restore not working

Hi,
I am using Vista Home Premium 64, and up to now everthing has been reasonable OK.

However every month ATI issues new drivers so this month I downloaded them but when I tried December's to install them it said that they were not 64 bit (drivers name is 8-12_vista64_dd_ccc_wdm_enu_72275), they also have Vista 32-bit which are called almost the same (8-12_vista32_dd_ccc_wdm_72275).

OK let it pass for a few days and tried again this time int installed but it would not allow the resulation to be set for my monitor at 1920 X1200 so I removed it again yesterdaay I tried it again and all appeared well but afterwards I am unabled to use
system restore. The error message states:-

The restore point could not be created for the following reason:

The writer experienced a transient error. If the backup process is retried, the error may not reoccur. (0x800423F2).

Please try again.

Well I did and got the same result each time. So now no System Protection Point also Restore Point This means I can not update some programs that require a restore point before they install as well as being unable to roll back any that did not work.

I have tried the Vista Forum and got the answer "Go to the control Panel then System - System - Systen Protection and clear the system restore catch (untick the box). Then restart the System Restore." This is supposed to start a new restore point. BUT IT DOES NOT.

This is doing my head in I beeen at it 10 hours today so far.

Anyone know the cure or has any ideas what to do other than reformatting the hard drive?
