Question PC Not Displaying after Crash

[waitedillon]

My PC crashed a few times while playing OW (temps weren’t that high or anything out of the ordinary). When I tried to start my PC back up, the monitor wakes up like it’s received some input but then it goes back to sleep. There are red lights on my mobo directly above the RAM slots, which is why I thought to replace the RAM. Below is what I’ve done since the issue started:

• Unplugged power cable
• Tried new outlet
• unplugged DP (primary input from GPU)
• tried running DP to other monitor
• cleaned out PC case with dust can
• replaced RAM with new RAM
• took out GPU and ran straight from mobo

include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time(if you can recall what version it was).
