A while ago I made the mistake of using MSI liveupdate to flash the BIOS for my board. It had the end result of turning it into a worthless brick, which I later discovered was a common side-effect of flashing my model of board with live update at that time. So I sent the board in and they sent me a different one back. My computer now fails POST unless I clear the BIOS which will give a chance of successful boot of about 3% of the time. The error lights inform me that it is a memory error, however, my memory works fine in another computer and other memory from another computer does not fix my problem. I removed all unnecessary hardware and swapped out for a different video card. Did not fix the problem. I also tried every different BIOS version. Remember I said that the computer will post 3% of the time so I am able to run tests. I have done the following after successfully booting it. Prime95 one hour: Passed Memtest one hour: Passed Orthos seven hours: Passed 50 degrees at end. Now if I let the computer sit for several days and then clear the BIOS it will boot instantly for a few reboots and the start failing POST 97% of the time. So I assumed the problem was the motherboard and returned it to MSI. Their response? Send me the exact same motherboard back with a different BIOS....... which I already tried. So evidently their "expert" opinion is that the motherboard isn't the problem. So what is? My thought? It booted fine a couple of times like it does for me (I told them about that) so they packaged it up and said "this guy don't know jack" and sent it back to me. I would like to add that if I try to change the ACPI standby mode from S1 to S3 the computer freezes. It also randomly does this if I try to select Advanced DRAM configuration to change it from anything but auto. Let alone even change the timings. However, this is a rare occurence.
