Fallout 3 Ruins Computer?

Okay, I just bought and installed Fallout 3. I played for about an hour, then the game stopped responding. I exited and went to bring it back up, only to realize it decided to now "detect my hardware" for the "first time," a process I already went through. I loaded up the game and found that it hadn't saved ANYTHING, even though I had been telling it to save. Now, I went to play COD2 and now that game won't last 10 mins without not responding, a problem I've never had before. What's going on? Are these things related?

Also, there was a weird popup when I first loaded Fallour that said I need to sign in and choose a storage device, something requried on the 360 but not on the PC. I signed it with my live gamertag, but still got the message about the storage device. Weird?

Did you read the title of the post? It says "Fallout 3 Ruins Computer?"
If you read the first line of the OP, he said "installed". You do not "install" on the 360. So I think its safe to assume its a PC.

Really weird, just to be safe run a check for virus or other malware and update your drivers. Fallout has some bugs and crashes but nothing too groundbreaking like you're describing, especially if now it's happening with other games.

We'll soon find out in like 2 days after i got it to work on win2K.
hopefully it works right.
A old but golden hint is always.. have a program that backs up your registry , either automatic daily , or manual , that way if anything happens , theres a like 80% chance with the backup you can restore your system settings again.
I have learned the hard way , playing a game that crashed and corrupted the NTcore something , wich seems to be the sofware CPU from your OS or so the errors says ., whereafter you gotto reinstall windows again , unless you back up something . i am so happy i backup 2 times a week haha , it saved my ass more as once

To answer Trialsking, yes i did read it...3 times in fact and was still confused.
But i guess i must have missed all those Live Gamertags on the PC -_-

The saddest part is that im not even overclocking. Just a really bad stock CPU cooler. I have a new one coming in a few days that will hopefully fix the problem. Freezer pro 7 or something like that. I'm looking at coretemps right now, with only Firefox running, and on average they're all 57 C. When I was doing a macaffee scan last night, they all went up to 90C.

^ +1. Reset the heatsink (or wait for the new one) and make sure to clean the old thermal paste off and apply some new paste

well, if hes getting 57 idle and 90 load, i doubt it has anything to do with drm.

it's clearly your CPU - my advice is leave it until you get your new cooler, then use your pc. You don't want to fry it just for the sake of a couple of days' gamimg....... What case have you got btw? It's v. important because it could be giving really low air circulation or letting in too much dust which is clogging up your psu fan, cpu fan, mobo and ram. Have a look - clean off the dust with compressed air. If it's air circulation, tidy up your wiring to improve flow. Good luck mate!

I didn't think fallout 3 was a drm game..

My case is the NZXT Zero. Here is a link if you want to look at it:

I don't think this is the problem, as the system usually runs around 38C on load, which I think is okay. Does anyone know any good system temperature monitors? I used to use AI Suite, but that stopped working so now I don't know how to monitor case temperatures.

The graphics card is an 8800GTX, if that helps.
