OK guys.... I never actually got around to doing that memtest thing, 'cause I was busy and stuff, and there were too many power cuts happening
But I wanted to report something rather odd that just happened... I just got on here and tried switching on my computer, but it wasn't switching on... so I removed all three RAM sticks and sort of wiped them and installed them in again, and guess what? When I got to POST, it showed that I have 2 GB RAM + 8 M shared memory... unfortunately, before it got to the Windows screen, my computer restarted and when I got to POST again, it said "OC Fail, please enter settings..." blah blah, you know that. So I wasn't sure what to do, so I went to BIOS setup and loaded default setting (there seems to be no "fail-safe" option there) and when I saved that and exit from BIOS, and got to POST again, I was back to seeing the "Memory Testing: 1048576K OK + 8M shared memory" thing.
So now I'm wondering - is there a specific sequence in which I'm supposed to install these RAM sticks? They're DDR2, but one is 400 MHz, one is 533 MHz, and the 1 GB one is 667 MHz. I have four RAM slots. Because I remember when I first got the computer, those RAM sticks were installed in some specific order, it's only after that power outage deal that I switched the RAM sticks around and put the 1 GB one in slot 1 (that's not where it used to be previously - I think it used to be in slot 4, but I can't remember).
Or do you still suggest I go ahead with the memtest thingy?
