Greetings, I've had this DFI P5BV3+ Rev. B3 for a while now and it has introduced all sorts of headaches for me since I first got it. To make an (overly) long story short, I've finally managed to get it to POST properly, however it won't for the life of it hold any CMOS settings.
I'm convinced that it's not a battery thing, since this happens even if I don't power down the system and pull the plug. In fact, the board will complain about CMOS reset at first boot and will not nag me any further after multiple resets until I actually go in the BIOS and save any settings I've made. At this point, it produces the same error message as earlier and the cycles goes on.
Initially, I thought it was a bad flash and seeing as it had an older BIOS to begin with, I went ahead and flashed the latest BIOS in the ROM. No dice!
Then, I thought the EEPROM itself might be dying so I went ahead and flashed the latest BIOS on a couple of compatible EEPROMs I had laying around and tried again. Again, no dice!
So what could be causing this? I have a couple of theories:
- The board requires a battery to save CMOS settings, regardless of whether or not it's plugged in or not, and something's gone bust in the battery "holder" and it's not making proper contact with the battery.
- Some of the capacitors have gone bust and are causing this issue. Trouble is, all of them look to be in good shape visually, so I'll be going blind into this, plus I don't have a soldering station and removing them with a plain 25-35W soldering iron is a bitch.
Anyone care to chip in? At this point, I'm out of ideas and it's always nice to have a fresh set of minds look into this and suggest possible solutions. So, what am I missing ? 😀
