So I have this laptop that I just replaced the motherboard in (Laptop is an MSI GT60 with an i7-3610QM and 12GB RAM). The original motherboard had damage to the power jack, so I got a new one off ebay and installed it this morning. Now, when the computer powers on it shows a blank screen, except for a tiny "99" down in the bottom right corner. After a minute or so, the text changes to "A2", and then after another minute, it loads the BIOS. Motherboard had no CMOS battery with it, so I had to reset the date and time, but other then that everything looks to be in order in the BIOS (RAID drive shows as intact and healthy), but when I exit the BIOS, it just goes back to the blank screen with the "99" in the bottom, and starts the whole process over again.
I've worked on computers for years, but I have never seen anything like this, and it's got me completely stumped. Am desperately hoping that I don't have to get a different motherboard, but at this point am thinking that may be the only option. Does anyone else have any ideas or thoughts?
Thanks in advance!
