Hi,

I have a HP Pavilion Desktop - 550-127c, and I recently installed an additional stick of 8gb RAM (16 total now). When I did this the computer started up fine once, but then when I started it up again later, the screen went black and didn't acquire a VGA signal.

I read this might be caused by dust in the RAM slot, so I took the RAM out and blew the dust out, and reinserted the RAM. I started the computer up and it started up fine, and I confirmed through the computer software that 16 GB was indeed installed. However, later when I started my computer again, the screen couldn't acquire a VGA signal and went to sleep.

Any idea what is going on? Please let me know if I need to include part specifics. Thanks.
