When I booted up my computer today, something wierd happened.
A black screen appeared and In the lower right corner the symbols A2 appeared, I then clicked Enter twice and the symbols 90C appeared and then they dissapeared and the PC started booting normally. I then turned my computer off just to check If It would happen again, as It was shutting down a blue light on my MOBO (that Ive never seen before) started blinking (located beneath my GPU) but It stopped blinking and my computer shut down without any Issues. I then turned It on again and a black screen that had all my computer specs on It like: Intel Core TM 3.20Ghz, ram, hdd and how many things were connected via USB etc. Then at the bottom I was given the option to click F2 and "Continue". I clicked Continue and I landed on the screen with the symbols A2 again, after 3 seconds there It automatically went over to the 90C screen, and after 3 seconds the computer started booting up normally. The computer runs like normal and no wierd sounds or anything from It. What do you think could have caused this? Is there anything I should troubleshoot?
