Question gpu led solid white on motherboard

[Blazing axel]

a few days ago , while playing a game, my computer lagged really bad, exited out of the game and rebooted computer. did a test to see if the problem was resolved by watching a youtube video. after a few seconds of the video , my computer got very laggy/slow and the sound through my speakers sounded like it was going to blue screen but froze. powered off. reseated everything on the mobo except cpu. But this morning ı push the power button and this time no Output on monitor but the cpu fan was still spinning and the gpu fans would spin on boot then stop few seconds later, spin again , and stop. Then ı saw gpu led solid red. What may İt be ?

Welcome to the forums, newcomer!

How old is your unit? You might want to source(borrow, not buy) a reliably build PSU that has slightly more power than you r platform needs and see if the issue persists.

My current GPU is a few days old. I plugged it in to my test computer to see if it was faulty and I got a full boot to the BIOS system. I have a old GPU that I put in my test system and it still works. I put my old GPU in my current and it didn't work. The only way I can get a display and boot into BIOS on my current bill is by powering my computer on and off multiple times until I can get into BIOS. It's getting power at least. Should I reset my CPU to see if that helps?
