AMD Phenom II X4 955, Reference GTX 460 1GB, Gigabyte SKT-AM3+ 78LMT-S2P Rev 5.1 Motherboard, 4GB DDR3, SSD+HDD, EVGA 500W PSU
My custom built PC, as above, has the very annoying issue of sometimes booting using the PCI-E graphics (GTX 460) and sometimes using the onboard (Radeon 3000) graphics, which can just about play Quake 2 at 60 FPS!
There is a workaround, but as I've built this for some non-tech savvy users, I want it to just work. The workaround is, if you unplug the PC from the wall for 10 seconds, usually but not always it will boot using PCI-E graphics. If I restart, it will not switch graphics cards. This means workaround 2 is to never shut it down. :(
I have tried to disable the integrated graphics entirely in the BIOS. This just caused the mobo speaker to play the long 'no video found - but I'll boot anyway' beep.
Any thoughts? Hopefully I won't have to replace the graphics card. I can confirm I experience no graphics issues once its booted. I have of course checked and reseated all connections.
