I'm sorry to hear about your computer issues. I had a bad time with a box I purchased, (pre-assembled and tested) from a vendor. I will not do that again. Since I wanted Linux they kept telling me that the system was fine and that the OS was the problem.
I was having memory issues the resemble much the same kind of thing you mention on your system--lots of mystery lock ups, bad starts.
I ran an mem-test X86. There errors didn't show up on the basic tests and was only when all the memory was in. I fought with the vendor for over a month to get it resolved. They sent it back to me a couple times and I tested in for a day or two, flashed the bios (vendor did an bios upgrade release), but still no joy. Turned out I was the only one trying to ru na full 4Gig in the box, everyone else was testing 2 gig strips independently and calling it good.
I finally to camera shots of the memtest screen an proved I wasn't imagining the issue. Finally the swapped out the memory to a different brand.
After that experience, I just bought a barebones system in a case I liked, and put all the pieces in myself. After the motherboard is in and mounted (which the barebones systems are) the rest is a piece of cake. Not that putting a motherboard in is hard. Just if you don't have a stash of screws, standoff, etc. it can be a pain to run around town to get the odds and ends.
So, I suggest you give than memory a thorough testing. memtest that comes with the ubuntu alt-install disk seemed to work okay for me.
After my memory problems were solved, I did a fresh install of the OS and never had issues.
