Hello Dell Community, I am currently out of ideas and would appreciate any help. First off, I'm a computer illiterate, so I'm doing my best to understand computer parts and names. Please excuse anything mentioned that doesn't make sense . I purchased my Aurora R7 in May 2018, and the PC wont turn on anymore on 3/11/2021. Currently out of warranty, and I was hoping to get it repaired by some basic troubleshooting. I normally use the PC for gaming, some light browsing and watching youtube, and I always shut down the PC through the start menu when I'm done with the computer.I've been doing a lot of research and consulting help from my internet friends, but we're at a point where I don't know what else to do.Here are the following things I've performed and tried to do, but I will first post the troubleshooting I've done to get some sort of a response out of the computer: 1. The first thing I've done from troubleshooting is to hard reset, unplug the power cord and made sure my outlet worked fine. It had booted to windows 10, but as soon as I move my mouse to continue my regular activity, the computer restarted itself, and I was faced with a blue screen stating that windows did not shut down properly, so my only option was to restart. After a few loops, it went to diagnostics, and lastly, spat out a QR code: [URL] There was no other option but to shut down from this point.2. The second thing I've done to get the computer to get some sort of a response was to leave the computer unplugged, with the CMOS battery removed and had it sat out for 2 nights before I had a chance to purchase a new CMOS battery. When I popped the brand new CMOS battery in and plugged in the power cord, I got a response, and it even turned on with the fans running for about 3 seconds. I did not catch if any amber lights were flashing as found on other discussions. After that, the computer will not respond.3. The last time I got a response was when I had a friend walk me through troubleshooting from helping along with research. I was told to disconnect cables from the motherboard, basically anything that powers up the computer, and then was told to move some blue caps over the jumper pins (no idea what that is, but it sits near the the SSD chambers) and perform a power drain. When I plugged everything back in, I finally got a signal. All fans were running, and I even see amber lights (5 blinks between intervals). However, I was unable to plug in a monitor or other peripherals, so I had to shut down the system to try again. Once I've plugged in the remaining peripherals, the computer stopped responding. *Also to state, I have tried to push the button next to the power cord on the PSU. All fans except the PSU fan were running at this time.--------------------------------------------------------------------------------------------------------The following were troubleshooting that I've tried to do that did not help at all:A. I've purchased a brand new power cord because I noticed a burn mark on the plug on the old cord. The computer has no response in spite of this change. B. I've tried to remove parts from the PC: RAMS, GPU, SSD, HDD, and performed a power drain as I plug each part back to see if it would respond to any of these plugged in one at a time, but I got nothing. C. I've removed most of the cables from the motherboard (except wifi card), removed GPU, and RAMS, removed the CMOS battery, performed a battery drain, and made sure all cards, and cords were re-seated snugly back to its place. No response whatsoever after the power plug goes back in. Again, the button next to the power cord on the PSU had all fans except the PSU functional. D. The most recent change was, I had another friend who helped look into a possible new PSU that I've purchased from Amazon: EVGA Supernova P2 650w. The PSU came in yesterday, but after giving 3 tries of plugging and unplugging cables, the computer did not respond. I finally unplugged all cables and ran a CPU / Motherboard only test with the PSU. Computer wont respond at all.As this is starting to get complicated, and frustrating, I'm out of ideas. If there's anything else I might have overlooked, I'd appreciate any responses / extra help. Thank you for reading.  
Aurora R7 will not power on. Have performed a lot of troubleshooting.
