CMOS Checksum Error Defaults Loaded: Post Transcend TS-USB3 Install

Hi there, I was hoping someone may be able to shed some light on this as it's got me completely stumped, and pretty down at the same time if the truth be told. I'll outline the problem below although the title of the thread may actually be slightly misleading.

My system is as follows:

ASUS M2A-VM Motherboard
Athlon X2 Dual Core 5000+
4gb DDR2
250gb primary SATA HDD
500gb secondary SATA HDD
Windows 7 Professional 32-bit

I thought I'd buy me a USB3 expansion card (transcend TS-USB3) to take advantage of the speeds my new external HD would handle. It was a five minute install putting it into the PCI-E slot, but when I turned my PC back on I got the CMOS message in the title of the thread. I continued into Windows with no problem but noticed my clock and date had gone completely out of whack. I corrected that but then had trouble installing the drivers for the card. I rebooted the PC only to get the CMOS message again, so I had a nose at my BIOS settings where everything seemed fine.
I booted back into Windows and re-downloaded the drivers from Transcend's website. They installed this time with no problem, and the PC picked up my new external HD. Then I noticed the real problem; as I went to start moving files from my secondary HDD to my external HD, the secondary HD had disappeared.

I've unplugged the HDD and rebooted to no effect, I've checked the BIOS and that sees it, I've even disconnected the USB3 card and rebooted to no effect. I just can't get the PC (just Windows by the look of it) to see the HDD. It's very problematic as I had a lot of movies and TV series' on there to back up, and while they're not important, they took me a long time to collect.
I don't want to buy another HDD just to check to see if it's that that's failed only to find out it's something different. As you can probably tell, my primary HDD with my OS on is working fine.

If anybody could shed any light on this at all I'd be very grateful. I've tried a Restore Point which didn't work either, and now the card itself isn't even working. I'm completely stuck. Thanks in advance for any replies.

A couple of pertinent pieces of information to add to the OP. I forgot to add that the Checksum Error has completely disappeared, it only happened three or four times but Windows boots normally now.

Secondly, the USB3 card is now working again and the external HD is detected and working perfectly. I just can't figure out for the life of me how to get Windows to see the secondary drive again.

One final post in here. It now transpires that the BIOS isn't seeing the HDD now, so it appears that it's a write-off. Sorry for taking up board space with my inane ramblings. I think I'll stick to external hard drives for mass storage in future.

I just installed a new battery, which I also checked with a DVM, so I know the battery is not the problem, but my secondary rig will only retain what I set in the BIOS until I turn off the power switch or unplug the computer.
