I built a PC for my sister several months ago, and it was running fine until last weekend. They had a power outage (the PC was on a surge protector however, and it was a full outage, not just a surge). Now, the computer will boot, but won't get past simply listing the processor and that Dual-Memory mode is active. It doesn't even get to the point that'd normally be on the same screen where it lists all SATA devices, etc. I can't access the BIOS or boot menu, but keyboard support is active, at least for a second. Do you think the problem is the BIOS itself or the entire motherboard? The PC is running WIn 7, which doesn't really seem relevant, since it can't even get to the point that it would try to read the hard drives. The motherboard is an AS Rock K10N78M. The RAM, HD's, and graphics card all appear to be fine. I can understand some function of the mobo possibly having been fried, but if it's just the BIOS, I don't really understand how a power outage would have affected it.
