Try the 2.8.11 version and see if it will write over the old one and fix the issue. If it does don't ever update it again. If you install the OS open the case and unplug the thing and make sure you install the same version of ACC again. Better safe then sorry I believe.

Also, don't put that CD in your drive again. You don't want to take that chance ether. It could brick it. Only use drivers from the Dell support site from here on out. You can run the PSA test through the BIOS, hit F12 and scroll down to the pre-boot system test thingy and run that. There is no need for that CD anymore.

Tesla's write up on it is the best around. If you used that then just do what he said again.

Yes, a Jedi Mind Trick might help    I am running AW-CC v2.7.25.0

Dell never wrote a proper AW-CC MIO-Board driver erase utility. It installs it's drivers in a strange PnP hidden way and then MIO-Board itself is not categorized in Device Manager in a conventional way.

After a clean install, if the MIO-Board is not responding:

- Try Power Dissipation Fix

- Try testing MIO-Board with Dell Diags (sometimes this will reset it)

- Try clean installing a know good working AW-CC version (for your machine model ... there are several different MIO-Board versions)

If all that fails, and the MIO-Board still tests good in Dell Diags, try a fresh clean install of Windows and it should work this second time.  We have seen users have problems with this. Either the drivers don't get installed properly that first initial time or Windows MIO-Board drivers get corrupt somehow. Definitely a "Windows problem" because a second clean install fixes it.

We have also seen clean Windows installs kill MIO-Boards (maybe it's the hardware detection phase or something). Anyway, that's what the "dis-connection step" is all about. You can identify this problem because the MIO-Board will stop responding in Dell Diags (outside of Windows).
