No GPU tasks on my laptop since it was reimaged. Plase help

(moderation:
I run Einstein@Home on my work laptop, Dell Latitude E6520 which has an NVIDIA NVS 4200M (driver version 8.17.12.9679) and Intel HD Graphics 3000 (driver version 9.17.10.2867) display adapters, both of which are working properly according to the “Device Status†attribute of properties. I had a disk crash last week and had the disk replaced and the computer re-imaged. Prior to the disk crash Einstein@Home would also run on the GPU but since I've gotten the computer back I have not been able to download any GPU targeted tasks and was hoping someone could help me figure out why. In theory the only hardware change to the computer is the new disk drive but as it's a standard company image I'm guessing that the device drivers also would have been updated to newer versions
On my local BOINC manager I have “Use GPU always†selected and when I request new tasks the message in the log is “Requesting tasks for CPU and NVIDIAâ€. As far as “Computing Preferences†I don't see anything related to GPU, but these have not been updated in probably years. On the “Einstein@Home preferences†all of the “Use GPU†preferences are set to yes, “Run CPU versions of applications for which GPU versions are available “ is set to yes and the “GPU utilization factor†preferences are set to 1.
I'm pretty much stuck and have not been able to find anything in the FAQs, searching the message boards or Google. Any help or suggestions would be greatly appreciated.
The computer is running Windows 7 Enterprise SP1, 64 bit and BOINC Manager 7.4.42, which was installed Thursday.

From your server log http://einstein.phys.uwm.edu/host_sched_logs/10679/10679146:
Your re-image has brought in Driver version 296.79 for your NVIDIA NVS 4200M GPU.
That driver was in the middle of a range of drivers found to be buggy, and this project won't send GPU tasks to a computer using it. Upgrading to a newer NVidia driver should fix that - get your driver from nvidia.com, not from Windows Update.
BTW, to avoid confusion - you have installed BOINC v7.2.42, which is the current recommended version - no problem there, just a small typo. And - unfortunately - your Intel HD Graphics 3000 is just too old to be used for crunching here: 2500 and 4000 (and later) are supported, but not yours.
Updating the driver resolved

Updating the driver resolved it. Thank you very much for your help.
