might have spoke too soon MBP 15 2.2 issues

I will preface this by saying my MBP has been working flawlessly until now...

Downloaded todays updates etc installed them and restarted. Everything seemed fine till I tried to open something, beachball instantly which isnt charateristic of this machine waited a second didnt change, cursor still moving but cant access anything waited some more, still nothing had to power button restart, tried once more same deal. Comming from PC land I tried to start it in safemode which according to apple support site does a bunch of other stuff that may fix the problem did that seemed to do its thing for bit got to desktop then restarted, now it just goes to apple screen spins for a bit and shuts down. Used disk utility Cd wont even complete disk repair just halts, tells me I need to reformat and reinstall. Which I am doing but should I even bother reinstalling any apps and just take it back for a new one its brand new and crap like this shouldnt be happening. I know I am pretty much an apple noob and perhaps may have done something wrong but I am pretty sure this isnt normal right ?

oh
I7 2.2 750gb hd standard res only thing not stock is 8gb gskill ram but that has worked fine for almost a week now

Would the ram really cause my hd to not pass the verify stage of disk utility even. In my experience ram going bad usually doesn't even let you go that far, it usually won't let you even post if it's bad, swapped it out anyway still a no go. It seemed to be working after I reformatted and it passed disk check even with the gskill ram in it and after os reinstall seemed to boot to the welcome screen just fine with either set of ram so it's def going back.
