Well... I can say one thing with certainty: When I have issues, they come in waves.
My primary system (specs in my signature), recently had a motherboard failure. That's fine, I can save my pennies for an upgrade. Now, my backup machine is having an issue that I can't figure out.
The machine in question is running Windows 7 Ultimate. It has:
Motherboard: MSI 890FXA-GD70 Motherboard
CPU: AMD Phenom II X6 1090T Black Edition Thuban 6-Core 3.2 GHz Socket AM3
GPU: HIS Radeon HD6870
I've suddenly lost all display. I have tried using five different displays, I have used the GPU that's in the machine as well as the GPU from my primary machine. I have swapped cables multiple times. I have tried using each PCI slot with each GPU. Each time I turn the machine on, the display tells me, "No Input Signal," or "No Signal."
Does anyone have a clue what might be happening?
