Windows 7: ntoskrnl.exe causing multiple BSODs, please help!

I've gotten Memtest to work now, booted from a CD. It's made 5 passes and had 0 errors, so now I'm even more at a loss than I already was. I also removed the driver used by daemontools, even though I got another BSOD after doing so.

Given that it keeps saying caused by ntoskrnl.exe, could the installation be corrupt somehow? I'd hate to reformat but I don't know what else to do =.=

I'm thinking IE might have something to do with this but I can't figure out how to uninstall it. Ever since the BSODs started happening, IE has also been crashing with the event name "BEX." I don't know if a Buffer Overflow can cause a BSOD but it might, and the timing fits.

Problem is I'm not using IE, ever. I've used both malwarebytes and Ad-Aware and neither of them turn up any Malware results, yet I keep getting "Internet Explorer has stopped working" out of nowhere. Even when I close it background processes keep starting up. I can't seem to uninstall it either, as it isn't showing up in the Programs list or list of Installed Updates. >.<

Specifically:

I've been letting it run while working for the past 6 1/2 hours. Nothing yet.

...Not seeing how that's helpful. If I knew what caused the blue screen then I wouldn't be here. The whole POINT is I don't know what I'm doing that causes it. Sometimes it crashes in the middle of League of Legends, sometimes it crashes when I'm not doing anything but chatting in IRC. The whole point of it driving me up a wall is that it's completely unreproducible. Still running though.
