This is an HTPC that I'm building. I am using a Biostar MCP6P M2, it has nVIDIA GeForce 6100 nForce 430 chipset, and onboard video. I also have a spare GPU card, it is a Radeon HD5450 GPU, so I decided to put it in. I figured GPU is at least better than onbard video. It worked for a month, but now it no longer boots. The board refuses to boot, I turn it on and there's no display or beep that signals a boot. It just turns on, with CDROM powered up, and case and CPU fans running, but it hangs there, there's no POST, or any signals.
Now I didn't think about any conflict between AMD and nVidia, but today I decided to try. Once I removed the Radeon HD5450 card, and ran the display from the onboard GeForce 6100 D-sub, the display came back, and the board POST'd just fine, everything works fine now. It makes me wonder if there's conflict between AMD/ATi and nVidia chipset. But then why did it work before? I ran Catalyst 10.10 before, but updated to 10.11 and 10.12 recently. It didn't happen until I changed to 10.12, but that's just driver change in Windows 7, shouldn't affect the boot up POST, or the BIOS load.
Any ideas?
