Alright, so I went to go upgrade my HTPC by buying a new case and a graphics card because it had just been running off of on board graphics chip and I had been noticing a lot of problems with playing the higher resolution video's and it wasn't porting out true 5.1 for some reason.
So it got the computer into the new case, installed the graphics card, plugged in the HDMI cable and after a installing a few drivers boom the thing started working... until the next day.
After turning it back on, because one of my room mates must have turned it off the night before, I noticed that it was just a black screen. then after plugging the HDMI cable into the port on the back of the motherboard it turned out it was running off the onboard chip again. After fiddling with it for over a week I have become fed up and I have no idea what to do.
Here is what I've tried so far:
So I am now stumped, it was working! but now it is not, and it's driving me mad! I'm willing to take any advice possible
Here are the specs:
MB: ASUS P8H61-I (REV 3.0)
GC: ASUS EN210 SILENT
CPU: Intel Pentium G620 Sandy Bridge 2.6GHz LGA 1155
RAM: G.SKILL 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333
HDD: SAMSUNG EcoGreen F4 HD204UI 2TB 32MB Cache
Have you tried putting another graphics card in the same slot in your machine? I had a PCI-E slot die on me once.
It could be the pci-e slot, but it could also be the graphics card. I've had issues with my laptop's ATI graphics card, and from time to time it didnt want to detect drivers.
ATI - All those installs.
@TEKUMS: I'm confused, are you running the HDMI off the motherboard's HDMI or off the GPU's HDMI?
I'm pretty sure plugging into the motherboard HDMI will make it use the Sandy Bridge onboard GPU.
@nickb64: If I start up with the with the HDMI cable plugged into the graphics card it will just produce a black screen. I've left it in there for a couple of minutes then plugged it back into the motherboard's HDMI to see if that one was still outputting the feed, and it was.
I'm going to try to place another graphics card in, I was going to try the other day but that requires me to also place my other power supply in because the oldest card I have is an 8800GTS 640MB which requires a hefty power supply and 2 PCI-E power outs. I'll come post the outcome once I've done it.
