If you’re not even reach a Windows splash/error screen you’re definitely looking in the right place for a physical issue of some sort.[br]


I’d pickup a PSU tester on amazon (https://www.amazon.com/Computer-PC-Tester-Connectors-Enclosure/dp/B076CLNPPK/ref=sr_1_1_sspa?dchild=1&keywords=psu+tester&qid=1610651632&sr=8-1-spons&psc=1&smid=A2KUFRYMC05E5D&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUFRQzA4QUJCRlVPMUMmZW5jcnlwdGVkSWQ9QTEwMDA2MTgyU1QxU1I3SzBMSFpLJmVuY3J5cHRlZEFkSWQ9QTAzMDA4OTMyRk1TTjJXSUExVzNUJndpZGdldE5hbWU9c3BfYXRmJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ==) and test it. If you for have a known-good power supply, I’d connect it and see if that allows boot.[br]


Additionally, flip your PSU power switch off for several seconds and then back on. I’ve heard of this resetting internal breakers in some PSUs, but I’ve never personally confirmed it/seen documentation of such. Haven’t searched/tested specifically for it though.[br]


If it tests healthy, a swap with another PSU produces no change, and the switch flip does nothing - potential motherboard failure would be my next stop for testing, but most of the time I’ve encountered that on the rare occasion I was lucky to still receive error beeps from my board for troubleshooting during attempted startup.[br]


Best of luck.
