So this happened on both brand new AW17 R5s, pretty much out of the box for me. The first machine i had for about 2-3 weeks, RMA'd it because of this issue and a couple other issues, and sadly this one has had the same issue since day 1, i've had this replacement for about 4-5 months i believe.
I just did a completely clean install 2 days ago hoping it would solve this issue (and some crashing issues i was having due to a DCOM error), as i thought it may be software related, but unfortunately it's still happening. The only work around i have found is to have nothing plugged into the machine when i start it up (besides my mouse dongle), wait for the alienware logo to appear and then plug everything back in.
Also, when i get the black screen, it is literally just that. No BIOS, no logos, no backlight or anything, just the Alien FX lights, and sometimes i can hear the windows sounds. So maybe its an issue with the panel or drivers, i just don't know. I've been searching for an answer to this issue since day 1, i've posted on multiple threads, forums, and have not come across a fix. The only reason i dont think it is a panel issue is because it only happens on start up, it's never just turned off while gaming or using the machine.
When i contacted Dell they wanted to replace my DC in port, which frankly i'm 99% sure is not the issue, unless quality is just that bad. It's hard to believe this as a hardware issue when 2 completely seperate brand new machines have the same issue, and as someone else has said, they also had 2 different machines have this problem.
