I tried to add two sticks of 1GB RAM each to my 32bit Windows XP system, it already had 640MB, 1 stick 128MB, 1 stick 512MB, so, I slotted it in and clipped the latches, but about 20-30 seconds after Windows boots, there's anoise like a 'brrp' and the system freezes, no mouse movement, no nothing, I tried the four sticks in various configurations, including putting it back in how it was before I started and putting the largest stick in where the previously largest stick was (what I assume was slot 0) but the problem kept happening. The second or third time I was moving RAM, one of the latches broke, but I didn't use that slot the next few times and the problem continued. I went into the BIOS, but I didn't see anything pertaining to RAM in there. Is it possible I hit something and caused a serious problem?
System:
Motherboard: MSI MS-7191
Windows XP 32bit
RAM: 640MB initially, trying to add another 2GB. All the RAM sticks are DDR PC3200.
