Weird Problems with K9A2 System

Question

Can Someone Help Me?
I recently built a new system and have had nothing but problems.  See system config in signature (Left off OCZ PRO Xtreme 1000W Power Supply With 4 12 Vrails at a max of 26 Amps each or 82 Amp all together and a 5 Volt rail at 30 Amps Max.) After putting it all (except the seagate 250 IDE drive), system would not even enter post. After strippin memory down to just 2 GB system finally entered post (although my memory were the same models from G.Skill one set was older and one set was new they had different voltages old required 1.9-2.0 while the newer worked at the default 1.8 voltage all timing and specs besides voltage were the same). I entered the bios setup and set my Memory voltage to 1.95 (What I had been runnin the older memory in my old system). Inserted all the memory back in and system booted right up to allow me to install my OS (Vista Home Premium 64-bit).
After the OS installed the system started having all kinds of wierd clitches/problems at one point it locked up and neither reset button nor the power button would work. After unplugging the power I noticed that the M connector for the front case switches was a little loose. I decided to just plug wires directly into board instead of using th M connector. Now my buttons worked again. I then proceded back into the bios and checked my voltages in the hardware monitor of the bios.  All voltages looked to be fine with only an ocassional voltage fluctuation in the 5V line from 4.97 to 4.92 Volts and the 12V line was a little high 12.4 Volts. However, after booting back into vista and installing Everest Ultimate Edition it detected the that the 5 Volt line was only at 4.67 Volts. But was not fluctuating at all.
After installing the drivers for my system and proceding to install my anti-virus software the system started freaking out the mouse started lagging and sometimes not responding at all and the keyboard worked intermittently.  I decided to remove the M connectors from these as well and that solved that problem.  Upon rebooting the system and trying to install the Anti-Virus software again the system started telling me that I had just plugged in something to the audio connector.  I had not so I just ignored it and continued to install my anti-virus.  (the audio connector alert popped up 4X while I was finishing the installation of the software.  I decided to test the audo so I but a DVD in and and watched the whole movie sound worked fine and no more pop ups about the audio connector until I started to install more software.  During the next install of software the screen went black and the DVD and Hard Drive LED stopped flashing. It stayed this way for about 10 Min. I decided to hit the reset button and the system would not enter post again.
Once again I started to pull the Memeory It finnally worked after removing the new memory that I had just bought but none of my Maxtor hard drives were recognized and I started smelling smoke. ( Strange only the Maxtor drives went out, all had the interface boards and one chip on each drive fried.  After disconnecting these drives and replacing the maxtor 120 GB IDE drive that had fried with a Seagate 250 GB IDE drive and reinstalling everyting onto it since the maxtor was my boot drive the system started up and was running fine except for the occasioal audio connector popup I finished Installing the rest of my software and everything was running good.  So I assumed the problems were due to faulty ram. I contacted NewEgg and arranges for an RMA  on the memory went shipped the memory back to NewEgg came back and started to move file some file to my NAS200 After about 4 hours the system locked up again (It had been almost 36 hours since I had had anyother problems with the system and it had not been turned off the whole time. All temps were good CPU was at 29C and GPU was at 46C system temp was 31C according to my Everest Ultimate so I didn't think it was a heat related issue) 
Upon restarting my computer I got a message that a recent overclocking attempt had failed (I did not try to overclock!!) After going back into Bios and resetting all my settings the computer would not post agian. I tried to clear the CMOS with the jumper just to make sure that there wasn't any coruption inthe CMOS. Still no Luck. Pulled out one stick of the older ram and it booted but very slow. I went to a local parts dealer and bought some extremely over prived memory just so I could get my system back to 2 GB because I had video edditing software that didn't work very good on 1 GB. After installing no post again. So I started testing each stick of memory that I had in DIMM 1 they all worked but anytime I insert one into DIMM 2 it would not boot.  Finnally I but 2 sticks into DIMM 3&4 and It started up and ran good. I decided to set my bios Unganged option to enabled and put memory back into DIMM 1 No luck would not post. I removed the memory from DIMM 1 and computer has worked ever fine except for an error coming out from sleep mode. (Never had a computer that didn't have a problem with that) I even updated the BIOS to 1.5 which was suppose to fix the wakeup problem. 
So here is what I have I can use Dimm 1 by itself or I can use DIMM 3&4 but not both together.  I'm about to buy a Power Supply (single 12V rail at 40 Amps and a 5V rail at 50 Amps) because I think that the 12 V reading as 12.4 and the 5 Volts reading as 4.67 in Everest Ultimate and 4.97 volts in Bios might have something to do with some of my problems.  I did not check the Memory that I RMA'd by them selves on DIMM 3&4.  I think that they may have been good now.
Can the 5V line registering the way it is 4.97 Bios/4.67 in Windows cause DIMM 2 to not function and create the lockups or can the socket or board be bad and that be what is causing this problem?  And Should I RMA the motherboard back or just purchase a different motherboard?
System is pretty Stable as it is now with the voltages as they are.  I really wantt to be able to put my new memory that I get back from NewEgg in and have my 4 GB of memory. 

Answer 1

OK I have removed the mother board and and checked for grounding issue or any damage from the fried hard drives board looks good did not find any grounding issues in the case.  One thing I did not check was that I was using a Startech SATA to IDE converter to connect the the IDE drives that I didn't have the connectors on the board or.
I did some research before buying them and made sure to get one with a plastic box around the pcb  due to so many people compaining that their's would short to the hard drive case.  Since the loss of the HDD I didn't need the adapter so I quit Using it.
when I did my research on the adapter I found that many people had said that their HDD got hoter when using the adapter I guess my HDD just couldn't handle it.  The Drive that I had connected with it was about 6 years old and I had been having intermittent problems with the connector not making a good connection when it was in my old system. (Anytime I would shut the power off for a long period of time and the HDD had a chance to cool down I would have to unplug and reconnect the ide cable from that drive.)
I didn't think that the problem would continue as I was moving it to an new case, motherboard, and cable.
And it just so happened that the drives that fried were all connected the the sata controller in the SB600 chip.  My two SATA drives that survied the fire were on the Promise T3 controller.  So I guess it is possible that the adapter/HDD configuration I had with the SATA to IDE caused some sort of feedback into the Motherboard's SATA controller and back into the oter HDD on that Controller.  I have checked all SATA ports since this happened and they all still work so I'm assuming that it did not damage the chip. 
As far as the memory  situattion I don't see how the HDD frying could have damaged the Memory unless there is some special connectin between DIMM2 and the SATA controller that doesn't exist with the other DIMM slots. and if it had somehow effected the memory controller to cause this problem I would assume it would have done alot more damage to the cpu than just the memory controller part. So I think I'll try to RMA a new motherboard, if ZippZoomFly will let me this long after getting the board I've had it for about 3.5 weeks waiting on the other parts for the new system) and see what happens.
As for the memory, itself they are not mixed brands or models.  I bought one set about a year ago when I purchased my X2 6000 processor and they have worked great as long as I kept the voltage above  1.9 V.  The new memory has the same model # as the old but the label on them states the same timings and only a different voltage range.  So as long as they voltage was set to within the range of both sets they should work exactly the same.  I did notice that the board would only detect 3.25 GB instead of 4 GB, and I was prepared for this. Every Motherboard I have ever owned, no matter who the Manufacturer was, has had this problem.  However Vista reported the memory correctly.
I guess if the new motherboard exhibits the same memory problem with not letting me use all  slots then i'll buy a 2X2GB set
