Hello there, 

My above mentioned motherboard was working fine until recently I encountered a BSOD, and instead of just restarting I went to the BIOS and changed the settings to default. I think by doing this the voltages for my RAM were messed up and I have been getting a C1 Error that refuses to let me boot my computer. This is just one theory I have but I am hoping you all have others. 

I have tried the usual steps of switching the RAM slots, I even bought a new 1GB stick of 1.8v ram because I thought it would work as the BIOS is default set to 1.8v, however this did not work. I have also reset the CMOS battery and jumper, and removed all the hardware and placed it back firmly in it's place. I am beginning to believe that my board is fried, but I have no idea how this happened as it is connected to a surge protector and nothing out of the ordinary has happened (I have not removed it, nor have any power outages taken place). Please give me as many suggestions as possible as I cannot RMA and I am willing to try anything else. 

Specs: 
Processor: Q9550 Quad Core CPU 
Memory: Corsair Dominator 2 x 2 GB 1066mhz 
Memory: OCZ PC2 4200 1 X 1 GB 1.8V (Used to attempt startup, but fails, leading me to believe my dominators are not faulty) 
Segate 500GB HDD 
EVGA 9800 GTX Graphics Card 
Operating System: Windows XP Professional x64 

Thanks for your help and attention, as this rig has been a huge investment for me and I would hate to lose it!

Yes I tried one stick at a time and nothing happened, just the same C1 error.

That's just it, I don't think so. I don't think I have the ability to RMA anymore because I didn't register 30 days following the purchase of the product. I guess a new board is the only way to go then?

I think you should make sure CMOS is completely cleared..I don't know how long you had the battery out for, but for CMOS to completely decay and clear usually takes a few minutes at least..Just simply resetting or popping the battery out and back in again just won't do it..You'll know when it's completely decayed/cleared when your date/time revert back to the stone age (Jan. 1, 2003 00:00:00 for example)..So you need to do this if you haven't already done so:

1) Power down and unplug your rig.
2) Hit the Power and Reset buttons a few times to discharge the Mobo.
3) Remove the CMOS battery for 10 minutes.
4) Put your Dominators in logical slots 0 and 1 or 2 and 3 (matching color slots) per the Mobo manual while you're waiting the 10 minutes to pass.
5) Put the battery back in, plug your rig in and power up..Now it should boot into BIOS however in a biotchy mood because everything in BIOS is at default settings now as it was on day 1 when it was made.
6) If you get into the BIOS, set the date/time and properly make all your custom changes (Boot order, FSB frequency, RAM timing, Voltage, bla bla, etc.)..Proper RAM timing/voltage is especially critical..If you can't get into BIOS or boot without an error then you have a basic hardware problem (Faulty Mobo, RAM, PSU, Video card, Hardware compatibilty issue, whatever code it spits out).
7) Good luck.
 
If you still get the C1 code and can't get into BIOS, it's memory related and either your RAM is faulty, incompatible, improperly installed, or your Mobo is junk.
