Windows 7: Help me overclock!!

Hey, I'm trying to overclock my Computer in order to play Battlefield 3 at ultrahigh setting flawlessly, I barely got any overclocking experience, and when i overclock to 3.6ghz my computer crashed and turned off while playing battlefield 3. Apparently they told me i didnt overclock right and it was unstable. Like i said before Im new to overclocking.
anyways here's my computer spec
Processor: i7 920 2.6ghz
Video Card: Dual ATI Radeon 5970's
Ram: 6gb
Power Supply: 1100 watts (or 1200)
Operating System: Window 7 home premium 64 bit
HardDrive: 1.15 TB (terabyte)
I have a Alienware Area 51 Desktop, and it has Liquid Cooling and fans that i can be powered up to 100%, apparently it has good venting system (Atleast that what i was told) i currently have it at 3.4ghz and its not crashing. How far can i overclock without worrying about frying any component? Anyways if u leave instructions or suggestion to overclock please list them, and remember im a rookie so try to speak in english, becuase i have a hard time understanding on what people are talking about .

You might want to list your LC system such as is it a closed loop like the corsair H series or is it a custom loop and what size rad. Two, three, or a single fan system etc......

What MB is in your system along with the RAM. 6GB really doesn't tell anyone much, is it 1600, 1333, 2000MHz, etc....

Don't forget that when OC there is no one size fits all, every system is unique but there are some settings which will get you started if we have the right information.

Hey Kipper! thanks for trying to help me out! like i said, i not a genius in computers so i really dont know what u were trying to say on the first paragraph, but it seems to me that your asking for more information. Well here you go

As of Fans, I really dont know how many there are but i got control over 2 of them in the Alienware Command Center, and the graphic card fans. And my CPU is Liquid cooled
here a picture of what my computer looks like inside (Sorta got it from a online site, but it look exactly the same, except the graphic card are much closer together) Dell Alienware Area-51 Core i7-980 X Infused Gaming PC - HotHardware. If you want more information about my computer you can check out Alienware.com and go to Area 51, so.. any suggestion? or anything else you want me to put down?

i'd say start by going to some overclocking fourms and read and make sure you no what you are getting into before
you do anything. then after that read more on the settings you need to change and how and where to change them.
after that always start out small and work your way up testing and retesting to make sure it right. keep a eye on your temps at all times.


scrooge

can you give me a link? becuase i looked under tutorial and i didnt see anything about overclocking.

Start here and read all the posts given regarding Overclocking....
overclocking

Heat will be your big problem and you better know what you are doing.

just do a search for (overclocking fourms)

If your wanting to put the graphics on max and have it run smoothly you will need to overclock your graphics card, you wont notice much if any difference overclocking only the CPU as the CPU that you have is good by itself. However overclocking a graphics card requires more experience than overclocking a CPU and as such i wouldn't recommend it as you may easily fry the gpu.

Overclocking sites are other sites devoted to OC. You are obviously new to this.

Just remember overclocking will shorten its life span and can result in instability.

Dayums you guys are making it sound like if im signing my computer death sentence by overclocking, Idk, in the information about the Area 51 it says that im pretty safe in overclocking due to its liquid cooling and its ventilation system, but ill make sure to be careful!!
