I built my first PC about four years ago and have had little to no trouble with it since I completed work on it. However, I've had a pesky problem that continues to pop up related to my HDMI output. Here is the most recent problem:
I powered down the computer, unplugged the power source and all other cables, and opened it up in hopes of putting an additional hard drive in. The hard drive came from an external USB hard drive in which the enclosure had stopped receiving power. As I poked around inside the guts of the PC, I realized I did not have all of the parts needed to install the new hard drive, so I shut it back up (without changing anything) and plugged everything back in exactly as it was before. The only problem is that now my HDTV (which worked fine before) no longer recognizes the HDMI signal from the PC. Here is what I've tried to fix this so far:
- Powering off PC then powering back on
- Turning TV off and then turning back on
- Unplugging HDMI cable from PC and TV and then plugging back in
- Using DVI to VGA adapter and attempting to plug into a VGA monitor (no luck here either)
From similar issues in the past and my own digging around tech support sites this time around, I understand that this might be solved by tweaking display and graphics settings on my PC. However, without any way to display the GUI, I don't see how I can access these settings. I will provide system specs to the best of my memory, but again, I cannot access any display so my information is limited:
Windows 7, AS rock motherboard, ATI Radeon HD 6870 video card, AMD quad core processor, Corsair 650w power supply, HDMI connected to Sony Bravia HDTV
Any help or advice fellow forum goers could provide would be greatly appreciated.
so you've tried it via HDMI into your TV... as well as vga into a vga monitor? (just wanted to be sure we're not talking about the vga port on your tv)
so thats two different output sources that are no go.
so a silly question... did you mess with the GPU at all? perhaps unplugged the PCI-E power cables, and forgot to plug them back in? (not as uncommon as you might think)
does your motherboard have video output as well? some do, some dont... you didn't list your mobo.
if it does, try output to either through that. In bios, there's an option to select onboard video or PCI-E video.
It shouldn't have been changed unless you were messing with the jumpers or CMOS battery... but who knows. Something to try

Turns out your silly question wasn't so silly after all! It seems one of the PCI-E cables got dislodged when I was moving things around. Thank you for your help, I really appreciate it. I was pulling my hair out trying to figure this out. Very much appreciated.
