Aurora R10, not turning on

If psu BIST has failed

If the BIST LED does not turn on or the PSU fan does not spin correctly, the power supply is not delivering power to the computer. Disconnect and reconnect the power cable to computer and try again. If the BIST LED does not turn on,

may need to replace the psu.  

@redxps630​ I pressed the PSU BIST button, after unplugging the PC and connecting the PC again and waiting a few minutes, the PSU BIST LED does not turn on, but for some reason it makes a clicking sound and a white light from inside the PC flashes. But if I press the Alien logo to try turn the thing on, it makes one clicking sound and then nothing happens. 

looks like the psu failed test.  clicking sound can be a short circuit protection mechanism being triggered inside psu.  I do not know too much about it.  if you have another 24/4 atx psu that works and you have a simple video card can borrow those to test pc.  if pc able to post then replace psu for real

@redxps630​ I'm confused how would the PSU break when I was just playing games then it started glitching so I shut it down. I din't have spare parts, how much does it cost for repair, I'm so worried because my warranty expired

to prove psu is bad or not bad need to borrow a working 24/4 psu from a friend.  not worth repairing a bad psu.  what is wattage of the psu in it now?  a replacement psu may not be that much but you want to make sure the rest of pc works before you proceed.  not sure whether a pc repair shop can do a diagnostic test for you.  

@frizzfrizzlol​ PSU breaks when they get older, it happens. It glitched because you likely lost 1 or more PSU rails.

If the Coin Cell Battery replacement does not work, a PSU would be the next thing I would change.

You can also purchase a PSU tester from Amazon to verify the PSU for around $20 to verify the PSU, before splurging money on a replacement PSU.

PSU Tester

Easiest thing to do first is change the Coin Cell battery. Will be around $5 at a local store.

Coin Cell Battery

If that makes no difference, the BIST fails and you get 2 blinking error codes on the Alienware logo, everything points to a failed PSU.

@Vanadiel​ Hey thanks, I think it's worth noting I used a plug extension to connect my PC, which was also powering my monitor too. Also about the PSU rail thing and you mentioning the PSU breaking, I moved houses recently, so the PC was carried in a van, God knows what happened to it, but it was working fine for a bit until I described what happened in the post... 

Thanks for the advice Vanadiel, I'll see what I can do with the coin cell battery.

@redxps630​ Thanks, I'll see what I can do.
