BSOD - STOP 0x7E . cng sys error. HELP!!!

i've got an inspiron 1750 running win 7 home premium. Couple days ago small tasks started freezing and not responding and yesterday i got bsod. I only had one chrome tab open at the time, nothing else. I've tried every selection on the f8 menu. computer gets bsod with all variations of safe mode and last known config. Tried removing the power cable + battery and holding the power button for 30 seconds. I've attempted to launch startup repair from the laptop and also from a cd I made prior to this. Both i've left for multiple hours yet they stay on the blue windows background with a movable curser. the disk i made previously shows the drop down menu for language but when i click next I get the windows background and curser.

Internal HDD is 1tb, partitioned 7:3. The bigger partition is where windows is installed and the smaller partition has a system image and backup on it from a recent point. If only I could reach the startup repair menu, i'd be able to select restore from previous point, and then select the system restore point in the smaller partition of the hdd. HOWEVER, I can't get that far.

Anyone have any suggestions as to how to get to the startup repair menu?? As I said before, all variations of safe mode fail so command prompt isn't an option. The primary partition is only a quater full.

Thanks very much for your help in advance.
