b) My computer now lasts about 15 seconds after logging into Windows before it freezes up.

It could also be that some component(s) are marginal -- running correctly most of the time with occasional failures at the margins. You might try backing off some of your BIOS settings to more conservative values, especially for RAM timings. Also maybe try boosting the voltages one notch for various processor and/or RAM voltages (don't over-do it -- just a little bit).
I had instability in my machine for awhile. It was very annoying. I had four sticks of RAM (actually six, but of course only four fit at a time). Four of them were 1GB sticks and two were 2GB sticks. Obviously I wanted to go 2+2+1+1 to get 6GB. I ended up rotating through the pairs to finally isolate that one or both of the 2GB sticks was not entirely stable. It worked most of the time, but I would get a crash about once a day on average.
I ended up doing an RMA replacement on the RAM, and the new RAM is working perfectly. But until then I was trying a lot of the same things you're going through.

I've found that sometimes memtest86+ has to run for hours before detecting an error that the win7 memory tester catches on the first pass.
