Hi all! First time for me in the forums, hope I could explain myself clearly.
Couple of weeks ago I've moved to another apartment and took my PC with me. After moving in, something strange happened:
When booting up, the computer shows me black screen and the monitor won't start; Only when I disconnect the monitor cable from my graphic card, connecting it to the onboard graphics and rebooting, Win7 logon screen appeared.
List of things I've tried that didn't succeed:
1. Exploring the BIOS hoping to find the option to disable onboard graphics. Never found it (apparently ECS doesn't have this feature, they've installed some automatic detection feature for external graphic cards) .
2. Removing the old graphics card, 9500GT, then reconnecting it.
3. Uninstalling the onboard drivers in Win7, rebooting, hopefully the system will recognize the 9500GT.
4. Switching monitors.
5. Looking for solutions in the internet. Read somewhere that it might be ground/voltage issues, so moved the PC from the floor onto the table.
6. Tried replacing the 9500GT with a brand new NVidia 630gt , same problem occurred. (On the way also bought 2x2GB memory cards)
7. Searched the web again, read that it might be a problem with the mobo, probably the pci-e slot.
I know some of the stuff I did is kinda stupid but I don't have high knowledge in HW... :\
Anyway, that's what I got so far. I really hope that I don't have to buy a new mobo. If you have any suggestions please comment!
Thanks in advance!!!
