I put together a build with MA78GM-US2H, Athlon X2 7750, 4GB DDR2-800 and Windows XP. At first I noticed some glitches - I couldn't get it to boot the Windows XP CD - it'd get into a reboot loop if I tried. After a BIOS update to F3, that was solved and I was able to get Windows installed, but I did also notice that booting a Linux LiveCD took a lot longer than it should've, and also that there was a 'black screen' pause that was rather longer than it should be when booting Windows.
After a couple days of operation it's now in a sorry state. BIOS POST takes approx 1 min, no errors are reported but it takes much too long. Windows then boots very slowly. Once up, the video 'jitters' up and down with some garbage displayed in the top few pixels of the display. It's also much slower than it should be.
I've run memtest86 and some CPU burn in tests with no errors. Swapped out the RAM for known-good modules, and disconnected all the hard disks and other peripherals.
Any ideas, or should I just RMA it?
