The title says it all - My Aurora R5 was in mid-update and the power at my condo went out for ~ 5 seconds (I was in the living room enjoying my cup of coffee) and behold, now my tower won't even boot. 

Here are some more information on the current status: 

• I get no "beep" warnings 
• The monitor gets power up for a bit when I try to boot the system. However, the external mouse and keyboard (set up through USB plug-ins) are not responsive at all 
• I've tried downloading BIOS crv directly onto a usb key, but with the keyboard being unresponsive I can't seem to make the system recognize / attempt to run this off of a usb either. 
• I believe my R5 does not have in-house BIOS recovery system since it's a bit of an older model (close to 3 years now I think?)
• The alienware logo at the front is AMBER when it tries to power up. The fan and the main power starts up for about a second and it shuts off. 
• I've tried resetting CMOS according to: https://www.dell.com/support/manuals/ca/en/cabsdt1/alienware-aurora-r5-desktop/alienware-aurora-r5-sm/clearing-cmos-settings?guid=guid-cb74f9e6-d57b-4d87-bd2b-92d47f957049&lang=en-us but the issue still persists
• I've read in other forums that taking out the MOBO battery (after draining the power out of it) and disconnecting & reconnecting MOBO power source can also re-boot the MOBO. Still no success here

Any other issues have / are experiencing the similar issue? I've also heard turning the power off during BIOS is a BIG no no and I'm beginning to see why..

Any help will be greatly appreciated, thanks!
