Monitor no signal after start up
So just today, I have this problem where my monitors does not display anything after start up. I would turn on the CPU and everything runs fine (fans, power supply, etc) but my monitors stay undetected as if my computer was never turned on.
I did some research and, so far, I've tried:
-removing all or some of my RAM and switching them through diferrent slots.
-removing and reinserting my PCI and my graphics card
-resetting CMOS through the jumper switch and battery
-unplugging everything from the Power Supply and replugging.
-pressing the CPU on/off button for an extended amount of time.
So far nothing has worked and I'm completely stumped. Everything was working fine until my computer randomly crashed darker today and then froze in start up to now not displaying anything. Any help would be highly appreciated and thanks beforehand.
My specs are-
-8 GB ddr2 ram
-quad core Intel
-corsair tx650 power supply
Is this a good question?
