PC Battery replacement

[Clint1000]

The battery died on my PC and I replaced it.  Prior to that I was running a program in Labview and using a PCIe 6343 with out any problems.  Ever since I replaced the battery it seems like there has been an issue with the Daq. I get "NaN" in any of the front panel GUI virtual gauges  I created and I get " +1.#R"  in any of my test results that I display ..both of which use the DAQ assistant to obtain a reading.  Could the battery replacement caused an issue or is this just a coincidence?

I can't imagine this effecting anything, unless (and I am totally guessing here) there was some sort of PCI bus enumeration held in the CMOS memory that was lost and rebuilt differently after the battery change.

That is it thinks PCIe slot #1 is slot #0 now or something like that?

Again only speculating here...

BTW: In the future you might want to replace the CMOS battery with the computer powered up. It won't hurt anything and you will not lose the CMOS memory.

It depends on your motherboard and BIOS. Some are simply hardwired but with others you do actually have configuration options in the BIOS. Maybe boot into your BIOS for once and check all the settings, then save it. Your BIOS may report inconsistent settings when starting up and maybe will automagically fix everything. Also make sure that your BIOS real-time clock has a valid date set. This goes usually lost when the CMOS battery dies and can't easily be set from the OS host. Some OSes won't even boot when this time is invalid.
