I got a new SATA III HD today and I plugged it into my desktop computer using the available SATA cable and power cable. Normally, the computer would just detect a new hdd, but when I booted up
my computer, there was the "check signal cable" message floating around my screen. I checked the cables and plugs and everything was in perfectly. Could the new SATA III drive have done something to my graphics cards or mobo?
I opened up the case to dust it out and reseat the graphics card etc, and I was able to get everything working again just fine and for a couple hours as I was checking the net, watching a few video files, checking my albums etc and backing data up....so everything was working fine on the MOBO. But I had to turn it off again and unplug everything to sort it all out after that was done (i had the case open and all the cables and wires out so I was just cleaning it all up and putting the case back on and arranging the cables to how I normally have it on my desk). Then when I booted up, the issue came back and there was once again no signal.
At first I thought it might be the DVI cable so I plugged the monitor in my 2nd computer (beside the 1st computer) and the monitor displayed everything fine so the monitor OR the monitor cables were not the issue.
The next thing I tested for was to see if the problem was my graphics card. I took the graphics card out and put it into my 2nd computer and it worked fine. So the graphics card was not the issue.
Then I took the original graphics card from my 2nd computer and decided to try and see if it would work on my main computer where the issue is happening. Upon boot up, there was no signal cable detected. Soooooooooo I believe this means that the issue is my motherboard?
Both graphics cards work on the 2nd computer.
But I'm wondering, does this sound normal to you? Is it possible for JUST the graphics card slot (PCI Express 2.0 slot) to go bad while everything else on the MOBO works fine as it was for me just earlier? If a mobo goes bad, doesn't that mean everything on the mobo won't work like the cpu too? My cpu works fine and everything else connected to the mobo but only issue is I can't see anything since the graphics card slot appears to be the issue.
My mobo is BIOSTAR AG880GU3
Now my dilemma is do i just buy a new computer or try and replace the mobo?
