Problems over problems!

Hi,
first, my pc decided to restart during startup, deactivating automatic restart on errors revealed a BSoD (Stop: 0x0000001E (0xFFFFFFFFC0000005, 0xFFFFF80002E95416, 0x0000000000000000, 0x0000000000000000)).

I tried booting in safe mode and it worked. However, although I remember having set the option to do minidumps of BSoDs, there was none for this one.
So I went to the dialog with the settings for that.
Here is what I got:
(See attachment)

Ok, then I tried the system restore and I got a similar useless dialog.

sfc /scannow tells me that there's a repair operation pending (or was pending) and I'd need to restart (and it still says so after several restarts).

When I try to use the system restore of the installation disk, it always fails telling me my drive D: (application drive) may be corrupt (chkdsk /R/F returns 0 errors).

The only thing that has changed were some security updates (kb2552343, kb2547666 and kb255698) and when I try to uninstall them, I just get "Ein Fehler ist aufgetreten. Es konnten nicht alle deinstalliert entfernt werden." (this is the exact message, translated it means "An error occured. Unable to remove every uninstall(?)").

Does anyone have a tipp for me what I could try next to find at least the source of the problems (preferably without uninstalling all the unnecessary hardware in my pc)?

Jup that's what I'd have done if noone has another idea.
Well thanks anyway :)

edit: ok just encountered a "small" problem:
for a repair install I need to start the setup with windows, however it doesn't work with safe mode and I can't boot up normally since I get the bsod then
Any other way to do a repair install?
