What I've noticed and tried.
When I boot my power-on self test screen says I have 512 MB when in fact I have 1G + a 512MB
One of my old 512 memory chips was acting strangly, So I replaced it with 1G and now I boot to black screen only sometimes not everytime.
Going in and out of BIOS to boot desktop doesn't allways work.
