I have a 775dual-vsta bios 1.90 with 2gb ddr2 4300 ram, 250gb sata Hdd and x1950 pro. Since i build my pc on friday i have several problems. Instability, and crc errors i first checked my HDD only to find it has no errors and doesnt have any problems. I then checked out my memory which came up with an 1 multiple bit error with s&m but no errors in memtest. I took my memory back to the shop and got both 1gb sticks exchanged only to find i got the same error again so this leaves me to think its not the memory. Please can anyone shed any light to what my possible problem could be.
