Alright, so. This problem has been going on for a couple weeks, now, and I've just dealt with it. But it's starting to drive me up the wall. SO. Posting it. ^^
I turned my computer on one day to find that, for one (and most noticeably), explorer.exe wasn't running. No desktop, no taskbar, all that good stuff. So I Ctrl+Alt+Del'd and ran it manually. Which simply opened up My Documents. Still no taskbar, no icons, nothing. So, for two weeks, I've been manually running everything through the Task Manager. Mildly irritating, to say the least.
Upon further use of my computer, I realised a whole lot of things aren't running on startup. For example, my Logitech applications for my mouse/keyboard. So, I decided to go ahead and check the registry to see if anything was messed up. All's well. I can't figure it out. Something's apparently blocking things from starting on startup, but I can't figure out, for the life of me, what.
Let's see. I've run a Window's Repair, I've checked the registry, I've checked msconfig's boot list... I don't know what else to try. I'd just reformat, but my backup partition is full and I REALLY don't feel like rearranging three partitions and transferring a few hundred gigs of data from two to the other. SO, if I can get it fixed otherwise, that'd be wonderful.
Thanks in advance for any help.
