BSOD even after full restore

[D_ave_N]

My Win 7 pc started running a bit slow so I thought Id do a quick restore.
The restore worked perfectly from the backup disk but I get BSOD the first time I try to 1) uninstall something (crappy acer factory loaded mcaffee trial) or 2) add a device (bluetooth mouse for eg).
After BSOD has appeared once then I get it everytime during boot.

I've tried:
Restoring again, both from the backup disk and the hidden partition.
Booting in the safe mode and running system restore (oldest restore point)
Letting it download all the windows updates before I do anything else.
Running acer updater for any newer system drivers
...all with the same result...BSOD

I am now left wondering if it could be a hardware fault but I dont know.
This takes me to the end of my home user knowledge... is there anyone brighter than me please?

Need to check you memory by using Memtest86:

Run Memtest86 for at least 7 passes. No errors are allowed

I've just ran it for 8 passes, 0 errors.

Any hard drive tests done?

How do I do one of those?

Go to Computer, right-click on the C drive. Select Properties, Tools, Check Now. Put a check mark in both boxes to set a disk check on the next start up

No problems found with that either.

Weirdly though, I tried restoring from a different windows disk (so not the hidden partition or the acer disk) and although I got bsod as a one off it seems to have disappeared now!

Maybe it was the acer software or more likely just fluke/luck.

Thanks for your help!
