HP VP17

Question

I have an HP vp17 monitor on a 32 bit Windows XP home edition machine that performed perfectly until today when I did a disk cleanup and defrag. After that when the computer rebooted the dispay resolution was grossly crude.
I went into Control panel and display to reset the resolution only to be given the following message: INVALID DISPLAY SETTING
The currently selected graphics display driver cannot be used. It was written for a previous version of windows and is no longer compatible with this version of Windows. The system has been started using the default VGA driver. I believe the driver on the machine is SP3451 and it is the only one that I have been able to find and it is defined as the most up to date. I do not have any idea why if it was compatible this morning why it is not now so.
It occurred to me that somehow in "optimizing" the new driver somehow got load and supplanted the old one however I do not know where these are stored to see if that is indeed the case, or how to force the system to load and use it if I could find it.
Is anyone familiar with this problem? And how it can be fixed?  
Its really impossible to use it this way as in addition to being ugly the resoltion is so bad that the graphics spill off the side of the dispay requiring scrolling back and forth to read or view, etc.
Thank you

Hello @GARDENZ,
I understand that your drivers for your graphics are not working correctly and you need assistance. I am providing you with an HP Support document: Using Microsoft System Restore in Windows Me and XP, which I would like you to use to restore your computer back to before you did the disc cleanup. Hopefully, this will restore your settings back to the way they were before. Otherwise, you may have to go into the Device Manager and manually remove and delete the driver for your monitor and then download and install the HP vp17 LCD Monitor Driver again.
