Sorry Bills I was talking about the board being soldered as apposed to a ZIF socket, but like Matt said, it would cost as much for soldering and parts as it would for a new motherboard.

The HDD's are unrelated to the checksum errors you are receiving. This is definately an onboard problem Zeld. If you could rule out the onboard battery for certain as it's a big leap in cost and effort between replacing a motherboard battery, and replacing the motherboard.

Most motherboards will work fine despite this error (since the default settings will be loaded if saved settings are not found). This means that if you are unable to pay for a replacement now, then you PC will still run happily in the meantime. It just means that every time you switch on your PC, your going to need to press F1 to continue. If you need to change any BIOS settings, you will need to do this every time you start your PC.

Yes, you're right. My PC is still running perfectly but it's really annoying pressing F1 every time i start my PC, esp. the internal clock, which then affects my clock inside windows. And I have to change that every time I load windows. ^^

Of course. Well I have a possible way around the clock problem. How about using something like this to keep your time up to date: Atomic Clock Sync Information from worldtimeserver.com

Also, did you manage to check that battery and the connection out?

Just one final question Zeld. When you switch your PC off, do you uplug and switch it off at the wall socket?

I have just recently observed something. When i shut down my pc, but keeping the AVR on solves the problem. It seems like a battery thing to me. But i have just replaced my old one with a new cr-2032.
Very weird.

If you look into the manual of a P4MAM2-v motherboard, there are two jumpers, one for clearing the cmos, and there's another one just beside it, which is called JBAT or something.
