BSOD after installing new RAM (W10 x32)

I just put a new RAM, 2GB, on my computer, and when I turned it on, it worked nice for about 3 minutes. Then it suddenly froze compltely with nothing responding.
First Firefox, then My Computer window, then everything, all this in about 10s. After another 20s, blue screen showing "critical process died" showed up. I managed to see that out of 4GB that I now had, 3,25 were usable (I thought W10 x32 supports 4GB?). I am uploading a report.
I am almost aboslutely certain that this had something to do with the new RAM since before that it worked just fine, and now fine again after I removed the new one.
Any ideas?

I solved this problem by switching the sockets, the older RAM is in position 1, and the new one is in position 0.
They were both Kingston 2GB 800Mhz, but the newer one had latency 6, and the old one 5, so I think this was causing a confilict, but it does not any more. Also, I intened to upgarde w10 x32 to x64 when I figure out how to retain the key I used for the 33bit install.
