I couldn't get into the BIOS, the computer wont start at all. When I press the button (I've also tried jump starting it from the motherboard, I'll edit the post, I did some troubleshooting today) I get zero response.

CPU: Intel i7 4790k Motherboard: Gigabyte GA-Z97X-UD3H-BK (Gigabyte Ultra Durable Black Edition) RAM: 32 GB Kingston HyperX Fury Storage: 1.25 TB Samsung 850 EVO SSD GPU: Zotac GTX 1080 AMP Extreme PSU: Corsair HX850i CPU Cooler: Corsair H100i v2 Case: NZXT H440 Fans: Stock Case fans

I built this PC a while ago and it worked fine for the most part. Every once in a while it'd randomly shut off, i'd give it a few taps, and it'd start again. However, this time it shut off and wouldn't turn on. However, when I plug in the PSU and flick my PSU switch on, the indicator light on the GPU turns on. I've tried: Checking the wiring Taking my CMOS battery out and putting it back in Putting in a new CMOS battery Swapping the CPU (swapped in an used Pentium I got off eBay) Jump starting the computer from the motherboard (with the original CPU) to no avail. Any help would be appreciated
