Told the computer for go to sleep one day like I have a thousand times before Later told it to wake up and all I got was a black screen. No windows, no cursor, nothing. Restarted the computer. Black screen. No windows, no BIOS messages, no cursor, nothing.
I had been running a Sapphire Radeon 7770 Vapor-X on an ASUS 890GX motherboard with an Athlon II x3 and 8 GB RAM powered by a Seasonic G-Series 450W power supply. OS is Win 7 64-bit.
Switched the DVI cable to the on-board (motherboard) DVI graphics output. Works fine, just can't game with it. "Aha!" I thought. "My video card has died. I am forced to upgrade." Bought a GeForce 960. Waited playing the occasional round of Dota 2 at 720p with minimal detail. Note that I left the Radeon 7770 connected for most of this time with power and everything, but I was using the video output from the integrated Radeon 4290 chipset on the motherboard.
New card arrived today. EVGA SSC GeForce GTX960. Installed card, connected power, attempted to boot.
Black screen. No cursor, no bios, no nothing. Moved DVI cable to the motherboard output again. Nothing. Unplugged power from the GeForce, left the DVI cable on the motherboard, normal boot. Thought, "It may be my power supply!" Connected my XFX 850W Black Edition PSU and disconnected everything but the CPU, motherboard, hard drive and GPU. Nothing. Tried the old Radeon 7770 for fun. Nothing. Tried both cards in the other PCI slot (the 890GX board has two, the lower one is supposed to use the GPU while the upper has a VGA switch card installed). Nothing.
At some point in here I uninstalled the driver for the on-board Radeon 4290 graphics. The motherboard display output still works but only at lower resolution. I cannot get either the old or new card to work in either PCI slot with either PSU. I cannot get the on-board graphics to work with either card when they are connected to the power supply. Oddly enough, when they are in the PCI slot but not connected to the PSU the on-board graphics work fine. This is a little surprising because when the issue first happened I left the Radeon 7770 connected to the PSU and the on-board graphics worked fine. It doesn't seem to do that anymore.
Anyway I'm totally confused now. I don't know if I have a hardware, BIOS, or driver issue or perhaps some combination of all three.
Any thoughts on this?
