I have the same problem -except worse. Computer was assembled by my son, who is experienced in this area. Problems started about a month after install, First noticed that the AOPEN DUW-1608/12x DVD-RW wouldn't write, then wouldn't read. Then the BLACK SCREEN problem arose. I was able to get into the hard drive over the network, even though the screen was BLACK. I would inconsistently get a brief message with the heading "Power Management" stating "Input signal out of range", then the screen would go BLACK.
I am able to get into BIOS. Screen displays perfectly when in BIOS and does not "BLACK" out.
I am unable to boot into SAFE MODE.
The only software running on the computer is XP, M/S Office 2000, Norton Antivirus, Mozilla, and M/S Internet Explorer, current version of NERO Express, and a memory manager. BIOS is two levels behind current - since the computer was working well initially, I didn't want to make any changes to add to the problems. I am running all default settings in BIOS. I am working on a LAN through a Linksys router and am connected to the internet over a DSL line. Full computer specs are posted in my profile.
If you have any questions, want me to try something, please let me know. The week after nest, I am expecting have one of my son's friends evaluate my situation. He works with Cuyahoga County (Cleveland OH) as a computer and network support person. If I find anything out from that, I will be pleased to let you know.
P.S. I have found AOPEN to be particularly unhelpful. Nero's impossible.
