No.. no, no... don't do that.

I had a RAM issue that Windows Vista failed to discover over and over again. It kept reporting all was just fine, although I had reason to suspect I had a RAM issue in one of my four 2 GB sticks.

I had to run Memtest 86 on it in full deep scan mode, runnign all the tests available, in multiple passes, to finally determine where the problem was and what stick was casuing it. It took all day but I finally nailed it down.

My vote goes to Memtest 86 all the way. Windows memory tools are crap and just basic, and  will not detect anything but very obvious problems.
