1) the power connection flaky...check to another available connection
may solve the issue.

2) If not, new power supply is where I'd go.

I opened the machine and snugged the cables (for all drives...). This
machine is six years old and only grudgingly--with a lot of fiddling--
allowed me to install Windows 10, so it may be time to start shopping
for a whole new one anyway Thanks.

fwiw, a friend and I each bought Alineware machines six years ago. He
does a lot of photo work for a living and I do a lot of professional
audio editing and some video/photo work too. Neither of us is a gamer.
The Alienware machines have proven to be rock solid and very good
performers (which is why be picked them). Based on our experiences with
the desksides, we each bought Alineware laptops a few years ago and are
similarly pleased with them. All four systems have undergone quite a lot
of tinkering and they've held up well. They appear to be very solidly
built, including the interior "fit and finish" (compared to run-of-the-
mill Dell systems that I'd had befoe - sharp edges inside and all). I'd
buy another.
