Go to SolutionArea-51 R2, USBs not working
I arrived home from a vacation and ultimately decided to turn on my September 2016 Area-51 R2. But, all power USB and HDMI coming out from the PC doesn't appear to power on, my monitor emptiness my mouse nothing my keyboard extinct. I tried replacing the CMOS battery but to no avail, tried swapping the GPU various times still nothing, tried a CMOS reset and still nothing.
The PC itself powers on fine but all the USBs appear not to work whatsoever, I've never had this issue before and it seems to have just stopped working while I was away, and since my warranty has expired (September 2017), I can't contact support but I have sent a renew form. If anyone has had this issue before or has a fix please could you post a fix?
Thanks in advance.

Sounds like a possible PSU failure. What model of Alienware is this?

Is it just the USB or no video at all? sounds like No POST if latter. This model is known to have motherboard no post occurrences reported by multiple users. try to find a spare working psu and simple video card that does not require 6 pin if available. test mobo using the working psu to see if you can get any video from simple card.

So there is no video and I get a message on my monitor saying there is no power coming from my PC, and all USB outlets have no power coming from them, as for the PSU It's weird that everything else works fine (Lights, Fans, etc) and just the USBs do not work, and I tried so far two video cards but still the same. I'm going to try to look into the PSU now.

I have a feeling that it is more likely mobo than psu. if you have an old working 24 pin ATX motherboard you could also test the Area 51 psu using the old mobo. If Dell psu can turn on old mobo and give video it would prove that psu is still working.

So I'll try giving a different motherboard a go and see what happens.

First objective is to get into BIOS. Also to run (built-in) ePSA Diagnostics.
Disconnect everything except monitor, keyboard, and mouse.
You test Power-Supply with a Digital PC Power-Supply Tester .
If that passes, you have a more serious internal hardware problem. Not sure I would bother. If you do swap motherboard, it should be an exact Dell/Alienware Area-51-R2 motherboard (if you want all fans and lights to work in the end).
IIRC, Area51-R2 was the first Triad-shaped model.

Turns out it was the motherboard.
