BSOD every day on first boot

Hello people,

For a few weeks, every time I first boot my computer for that day, it shows a BSOD during booting or just after logging in. After that I just restart my computer and it'll work fine for the rest of the day.

I've tried system restore, but that doesn't work and just shows a BSOD too.

Next time it happens, i'll take a picture of the BSOD and post it here. I'm unable to do that now because today's BSOD has already happened and I already restarted my computer without making a picture.

I was wondering whether it could have something to do with my RAM.

I'm running Windows Vista on an Acer Aspire M1641:
