Ok, lets get this done...
#1- Reinstall old card with new PSU and test.
2a-It works flawlessly
2b-The error still happens
2a-Now we know it is either the new card itself, a lack of power for the new card, bios settings, or drivers
2b-Now we know it is either the GPU, PSU, RAM, a bios corruption, CPU, or a failing MB.

Your PSU does not have a listed 12volt rail amperage on newegg...that could be bad. Newegg.com - OCZ ModXStream Pro 700W Modular High Performance Power Supply compatible with Intel Sandybridge Core i3 i5 i7 and AMD Phenom
Here are some unofficial numbers for it, stating ~2x25amp 12volt rails
Support Question OCZ700MXSP 12v rails -- GTX 460 SLI?
The video card wants between 31 and 38 amps, prolly more towards the 38 due to stock OC on GPU

It looks like your PSU is the culprit, stop fingering your RAM, it feels molested.
Lessons to be learned.
1-Don't buy stock overclocked stuff, period.
2-Don't buy modular power supplies, they cheated you on the 12volt rails. Just get some zip ties and keep house.
3-READ more before making purchases. Newegg and tiger direct reviews, when combined with detailed research into available products can help nip problems in the bud.
4-NEVER use the driver CD that came with your card, just go download the newest one and have a clean install of the most up-to-date work from the code monkeys.
Return the PSU (or keep it as a spare for a different computer) and purchase this,

I used it with a GTX470 flawlessly, it has 2x38amp 12volt rails, and I've never had an Antec PSU fail on me or my clients.
After seeing your PSU and GPU,low amps looks like your issue. Good Luck.
*note, spend a lil more and get what you pay for. This is running my GTX470 now,

I would also suggest using a high joule rating surge supressor AND an UPS to help protect your components. You already picked out a PSU with PFC, which is becoming standard now so less of a headache to have to look for.
I'd bet money its your PSU being under amped.
