First off I just want to say to anyone who offers assistance, or even input, I am extremely grateful. Little background. Built my second PC in Feb of 2017. First build went as you could imagine, but in the end it worked out. Second Build went smooth no issues and has worked great, until today. All the parts were brand new when I bought them.
GPU - EVGA GTX 1070 FTW
Motherboard - ASUS z170-E
PSU - EVGA 650w Supernova G2 Gold
2 HDD - 1SSD and 1HDD that never have had any issues. Recently started using an external about a week ago for files and some games.
So today I woke up, no work, so go on the PC to do some gaming. I say I play a few hours a day maybe 3-4 times per week. Sometimes more depending on if I have the day off. Anyways, all was fine today from about 7 am until 3 pm. I was playing games as I usually do and browsing the web. I started up Fortnite and grabbed an old mic and plugged it into the front of my case. Had some issues getting it working so I went into the device manager to set it up and all of sudden PC went off. At first I thought the power went out. Tried rebooting and starting it up, nothing. Been trying a variety of things and have had no luck. I can put a PC together but when it comes to issues like this I am pretty lost.
One thing I do notice when I have the PSU turned on there is a very small green LED to the left of the power LED that blinks every 3-5 seconds and there is a faint beeping/chirping/whine sound. Kind of like it wants to start but it cant. I took out the PSU and did the "paperclip test" with the tool EVGA provided. The fan turned on and it seems like the PSU is okay, but I know that just because it passes that test it still might not be giving out enough juice. When it was plugged in with the keyboard and mouse (they are backlit), the lights on the peripherals would flicker very quickly every few seconds. The PSU didn't seem hot when I inspected it right after the incident. If anyone has any input, or ideas, I'd be so appreciative. I am not sure if that LED blinking is some type of code. The ASUS manual makes no mention of blinking LED lights. If I can offer any more information just let me know.
