Utter Failure...

Ok, so I've tried running through the Read & Run me thread to make some progress, but to no avail. Let me kind of outline the issues I have here. (running on vista)
1. When I turn on my computer, it goes through the standard boot sequence, loads windows, (welcome screen) etc... However, instead of displaying my desktop and icons, I just get a blank screen. The only way I can do anything is by pressing shift 5 times and going through the stickey keys thing. Anyway, after approx 3-5 minutes, my computer will close all that out and I'll be looking at a blank screen again. (repeat pattern)
2. I know through the read & run me thread that I am at the very least infected with something called brontok, trojan.dropper/gen, and trojan.agent/gen-loader. (found that out from the superantispyware pgm) Unfortunately, before any of the programs from the thread can completely run, my computer will go blank again so I make no progress with it. Nor can I generate any logs...
3. I cannot logoff windows so I cannot finish the user account control. If I do try logging off, it just sits there forever!
Other items of note:
Before it got this bad, I realized i had something called new folder.exe problem. I tried searching the web for some assistance and any time I went to a site about it, my computer would automatically logoff windows and restart.
When I use the sticky keys method of getting into my computer, if i run a thing called desktop.exe, it'll display my desktop, icons, etc... everything looks like it's ok, but its very unstable then.
So, I know there's a lot there, but any help anyone could provide would be greatly appreciated! I know i'm making it difficult w/o having logs to post, but if your expertise could atleast help get me to that point, I'd be forever greatful!!!! Thanks!!
