I was wondering if your brand new sticks of RAM DD3 could go faulty after a hard shut down of a PC? No power surge and did not turn it back on immediately
UPDATE: Computer turns on but does not POST. There are indicator lights on the MB that state the RAM is causing the issue. When I remove the ram it does give me beep codes but other wise it does not. It was just working yesterday..
Update2:
I have 4 sticks of RAM, how can they ALL go bad? I have tried them in every combonation possible (single, double, triple,etc) I have tried every slot with each stick and same result.

There are a lot of reasons RAM can go bad. Too many to name.
You should run memtest86+ to verify that the RAM is bad. You can also find a copy on the Ubuntu install CD and other Linux boot CDs.
7As with any electronics, RAM can suddenly go bad.
Because your ram is relatively new, I'd try returning or exchanging it for a replacement.
4It's unusual for any chips inside a PC to fail without cause. The likely failure modes are damage (electrical or mechanical) while handling, overheating, damage (cracks) from thermal cycling, electrical surge, or corrosion on socket connections. Only very rarely does a chip "just fail", without some external cause.
Memory chips are particularly sensitive to static damage and are apt to be electrically damaged if not carefully handled during installation, especially in winter when static is a bigger problem. (Though newer technologies are an order of magnitude less sensitive to this than the stuff of 20 years back.)
Another common failure from the past for memory chips is corroded socket connections. While rarer than in the past, it's no doubt still possible for corrosion to develop at the connection, causing a failure. Traditionally this was dealt with by applying grease to the contacts, to exclude the air that causes corrosion.
