Hey guys,

I'm having trouble overclocking my E6600 from 1066 fsb to 1333fsb.

Specs:
Intel C2D E6600@2.4Ghz
2x1024OCZ 800MHZ CL4 DDR2
Gigabyte GA-965P-DS3 (Rev3.3)

I only want to overclock the FSB, so I up the cpu fsb to 333 and the multiplier to 7 because I want to keep the same speed.
then the computer restarts etc.. but it will only save the multiplier!!! So I was running 7x266 instead of 7x333!!!

why does this happen?

When I need to save or print my work from small scroll type boxes similar to this type of letter box, I can never print the entire message. Is there any type of software that will allow me to accomplish this command? The message box I am referring to is the one which you will use to reply to my question.

Is it just me? I'm fit and healthy, but I've noticed that when I sit with my laptop propped up on my legs or on my stomache, I get little niggles inside, best way to describe it is kind of adrenalin rush, combined with a bit of discomfort, kind of butterfly effect. It definitely only happens when I use the laptop. Is it possible that any nasties are transmitted thro from the bottom of the laptop, or am I imagining things!

**And if it is in fact cheaper to print your own, would it be worth my time to purchase a quality printer? (I'm operating under the assumption that a standard inkjet personal printer does not have the capacity to print out professional quality wedding invitations.)
So if this is the case, would you also be able to recommend a printer that would be capable of printing out my own invitations with that level of quality?

It will sync my contact, but not my email, tax list or calendar. Outlook keeps crashing and the sync process will not complete.

It seems that I can be playing for 15 minutes for 8 hours and then out of nowhere my computer just shuts off. Typically after this problem it also has trouble booting up, it gets stuck on the windows screen that shows the loading bar streaming across the screen. As I said before I am relatively sure it is not overheating(I have a CPU fan with heatsink, a GPU fan, a PSU fan, and 2 case fans. I have my suspicions about eh hard drive though, because in Windows in the bottom right task bar it shows the Safe to Remove Hardware button for my hard drive. Is there anyone who recognizes this problem, or knows of some place where I could get help, preferably a place I would not have to pay for-such as Best Buy or Fry's Electronics.
