This started happening a few days ago. I would be viewing a Youtube video or watching a stream on twitch and all of a sudden my displays would go black and my fans would ramp up like I was under full load for a second and then shut off. This was random. Sometimes the computer would stay on for 10 minutes or 3 hours. Thinking there may be a screw or stand off or something shorting out my board I removed it and put everything back in. Still same issue. Thinking it may be the GPU I removed it and tested it in another system I built. GPU didn't seem to be the issue. Thinking it may be the power supply I tested the 24 pin voltages with a multimeter and all seemed correct. I tried replacing the power supply with one I had in another system and still had the same issue. Motherboard and CPU are both only a month or two old. HDD and PSU are over a year old. At this point when I click the power button it POST's and then turns on with fans turned all the way up, and nothing on the screen and no code on the motherboard. If anyone could help shed some light on my issue I would greatly appreciate it! I am a fairly new PC builder and would love a response or two. Thanks in advance!
