I've been having a number of problems with a system I recently built, and I am beginning to think it might be the motherboard itself. Here are the specs:
Gigabyte MA770T motherboard
AMD Athlon II X4 630
OCZ Gold 4GB (2 x 2GB) DDR3 1333
POWERCOLOR Radeon HD 5770
Seventeam ST-750PAF 750W ATX 12V V2.2 power supply
Western Digital 500GB Green hard drive
Out of the box, I wasn't able to install windows 7 64, as it kept blue screening. I eventually pulled out a stick of RAM and got it to work. Seemed to be fine for a couple of days, then started freezing with vertical gray stripes filling the screen. It would always crash about 30 seconds into an avi file. This seems to be a common issue with the Radeon 5770, but there were other issues as well. I put in both RAMs, made sure the CAS settings were correct (9-9-9) and ran memtest. Both sticks came back with errors, always on test 8. I RMAed the RAM. After putting the new RAM in, everything seemed to be fine for a day or so - I tested out an avi file and it made a few minutes at least. I didn't have time to go all the way through, but it got past where it used to.
I then ran another memtest for 25 hours, with both sticks in, and it comes back with errors on test 5. It seems highly unlikely that I got two faulty memory kits, so now I am suspecting the mobo itself. Additionally, I have run Prime95, both with the old memory and the new, and it had errors.
Any suggestions on how to narrow this down, or should I RMA the mobo at this point?
