Computer won't post

[RedArmy]

The way this happened is actually pretty stupid, but nevertheless here I am. I was vacuuming the carpet in my room and I noticed a switch on the wall that I've never touched, so in my infinite wisdom I flipped it off. Well, my computer on the other side of the room went off so obviously that switch controlled the power to the outlets. Upon turning my computer back on I found out that it would no longer boot.

I've had this problem before and it's always been the memory, but I haven't had any issues with it in a long time. I have 2 sticks of Corsair Dominator CM2X1024-8500C5D (2.20V ver 1.2). They were in DIMM slots 1 and 3 on the MB (Gigabyte GA-P35-DS3L) like the manual says they should be, so the first thing I did was take both of them out and replace the one stick in slot 1 with a Crucial Ballistix module I had laying around. Well, that worked, so I tried putting the other Crucial stick in slot 3 and rebooted. Nothing.

So, I went upstairs, stole the memory from my dads computer (2x2gb of the same stuff I have but 2.1v [same timing of 5-5-5-15]) and tried that. Both sticks worked in slots 1 and 3 and I could boot up fine.

I fooled around in the BIOS and changed the System Voltage control to auto (it defaults to manual) and I then retried the two Crucial sticks and they both worked in slots 1 and 3.

Tried sticking my two sticks of memory back in and nothing. The computer won't even post. I don't understand how the computer could go from working fine to not posting with the exact same memory just because it lost power.

I've read on a lot of forums that there are some issues with this memory since it's 2.2V and I've tried bumping the voltage up +.6 over normal which puts it in the 2.2V range (leeway of a 100mV each way) and it still doesn't do anything for me.

Any suggestions?

Cliffs:
1.Corsair memory with stock 2.2V settings won't boot with my Gigabyte motherboard
2. Every other stick of memory I own will
3. FML

run memtest on the 2.2V stick individually and if any errors RMA them, i do believe they have a lifetime warranty.

just RMA and see if they will score you some 2.1v stuff in the process cause you are having compatibility issues. corsair support is usually cool enough like that to do an exchange if the memory you bought is having issues. i got to talk to one of their reps in person at frys a while back when he came in to brief everyone besides me on how to get customers the dominator GT kits they have been requesting, and he said that if they are unable to replace your memory with a working kit of the same stuff, they will usually send you a different kit (usually an upgrade) that's within the price range, within reason, unless they no longer make it, in which case they will give you something of equal market value to what paid when you first got your memory. idk how much truth there was to all that (marketing guy and all) but corsair is well regarded as being one of the most reliable manufacturers. i would check with them and see what they can do to keep that reputation lol.
