CMOS Error

Here's the set-up:
Late November I used an external drive to try backing-up some files on my desktop comfuser (it's usually used on my wife's laptop). I removed it correctly & all was fine the next day. We then went on vacation out-of-state (11/23-11/27); so I not only had the comfuser shut-down (as usual), but I also turned the comfuser's PSU power switch OFF.

Since coming back, when I 1st boot-up & as the POST is listed, I get this message:
CMOS checksum error - Defaults loaded.

Then right after I get:
Press (Ctrl+S) or F4 to enter RAID utility.

A few seconds later, the comfuser lists the POST again (really fast) then boots normally. Normally except for 3 things:
1. I sometimes get the "Windows needs to install driver software for your Unknown Device" dialog box. Which I click "Don't show this message again for this device" & enter my password (twice).
2. My clock is ALWAYS reset to Jan. 1st, 1996; which also gives me an Invalid Certificate message if I try going online & forget to change the clock 1st.
3. My 'alphabet soup' is now all jumbled-up. HDD is still C:, ODDs are still D: & E:; but my media card reader, USB ports & printer have been mixed-up a little.

I have always had only 1 SATA HDD & 2 PATA ODD & have never even tried a RAID set-up. The external drive has a USB cable. I went through my mobo's settings & no RAID is set-up & the HDD is the only drive set to boot. I don't know if this is a software/hardware problem, but can anyone help me w/this?

Well, found out that I'm looking for a new mobo after X-Mas.

I was thinking about either the:
Asus M3N78-VM -or- Gigabyte GA-MA790X-UD4P

Also, should I go w/an AMD Phenom X4 -or- AMD Phenom II X3? How much difference is there?

And should I stay w/my 2 PATA optical drives -or- get a new SATA optical drive?

Since you don't tell us what your current system is it must be using DDR2 based on your selections.
Did you test the cmos battery on your old board?
Currently the prices of the PII X4 are so cheap it's hard to say no. I've seen 179.00 for the 965 (the 125w is the best choice). The X4 955 is about 159.00.
The 790x-UD4P has won alot of awards! There is a limitation of 2 Pata devices though. On the good side it has 2 seperate Sata controllers offering 8 Sata devices. Including a 2 port powered external E-sata tongue connector. If the difference had only been $40 instead of $140 earlier this year I wouldn't have my X3 which does unlock and run easily at 955 speeds.

Since your starting off fresh makes more sense to get a Am3 chip, motherboard and ram.
