Need help with Fallout New vegas

I have problems with Fallout new vegas(Who wouldnt?)I have experienced freezes and crashes with my xbox when playing New vegas.Also sometimes i get the error:Disc is unreadable but the disc seems to be completely clean.Then,today when new vegas once again froze and I restarted my xbox i get e71 error.I restrated my xbox and it was gone.Then it froze again and I got it agaain.So,did the initial setup(had to do it many times coz my xbox froze during the progress sometimes)and now the error is gone.Now,when i launch my new vegas theres something with the main menu.I cannot skip the bethesda shit and obsidian shit productions and then when the guy with red lensed gas mask appears in the screen it doesnt show "press start "music still plays and all but i can not play the game.Sometimes,main menu is ok and it lets me skip all the beginning stuff but then when i try to load one of my saves it says:(now my computer fucking got blue screen.WHAT THE FUCK!And the E71 error is back.Fuck yeah.)anyways it says something about not being able to load it.What the fuck now.Thers two probs now.should i send my xbox to repair or do you have any advice how to fix this e71 shit?And what about the deal with new vegas?

Clear your system cache.

Did it.

Does that mean you cleared it, or clearing it "did the work" so to say?

In other words, does it work now?

Tried it plenty of times before and now too and it didnt work.

So it looks like I have some kind of software issue...

Just send it in, mine did this after a lot of Gears of War playing (Fucking GoW killed two xbox's for me already.) its a common problem now, almost as common as the RRoD.

Yeah I'm gonna do it tomorrow.Fucking third time my xbox got disfunctional.

First xbox broke after 5 years of loyal service.

Xbox Slim has had no problems so far.

I wonder if they give you a slim for replacement now?

I didnt send the xbox yet.I dont get the error message anymore.It was just some kind of dashboard update fail.Or something.Not hardware issue.

Well if the freezing keep happening send it in, my xbox did the same thing. It wouldnt let me play anything with better graphics then CoD 4 ( wasnt that beg of a problem CoD 4 is still fun) But it stopped me from playing zombies and LifeRP every week for about 3 months till i bought a used 360 and sent my old one in (this way i ALWAYS have a back up 360 )

thishappe to me the crahses i hech it it as fine i sent mesg to obsidan they aid it was cause there is just buttloads of stuff in the game
