My PC can't get to the Mobo screen, there is no POST, just black screen. All fans are spinning, CMOS has been reset both with the battery method and the jumper. Here is what exactly happened. One day I turn on my PC and it froze on the Mobo manufacturer screen, I restared with the power button and got to a screen with just a white cursor, familiar from the time I had HDD troubles, I pressed Control+Alt+Del to restart and Windows managed to boot. This was the case for 2 more days until my method stopped working. So I did what every novice does and started messing around with the hardware componets, checked most of the cables, all was fine, but the issue persisted. Then I relocated the RAM and something changed, but for the worst, now it was just a black screen. The system is old and stuff will break down, what bothers me is I am not sure which component is faulty, because I have spend most of my savings and cant changing everything inside. My gut tells its the motherboard, but the blackscreen reminds of GPU failure and I had the CPU reach very temps during the summer so it could have melted.
