Need some help overclocking please

Windows 7 64bit
Intel Pentium Dual-Core E5300 "LGA775 Core 2" 2.6Ghz (800fsb)
Seagate Barracuda 7200 12 500GB SATA-II 16mb cahe - OEM
Nvidia GTX470 1024mb
Gigabyte GA-G41M-E2SL Intel G41 (socket 775) PC-I Express DDR2 Motherboard
Corsair 600w psu
Corsair XMS2 4 GB (2 times 2gb) DDR2, TwinX Dual Channel

Hi, could anybody please suggest where I am going wrong with overclocking my system. Whenever I increase the FSB, even by 5mhz, my computer fails to boot at all. I'm sure my system can handle more. If I overclock from within windows I can get my 2.6ghz up to around 3.4ghz (13 by 260) and it runs prime95 fine and temps are ok. Obviously I want to do it properly in the bios but I can't seem to get anywhere.

I thought I would post the settings as they're shown in my bios...

  1. if your fsb wont go up, then its as high as it can go :P

    if you can o/c within windows, o/c within windows

    also, in bios try o/cing your processor instead of your fsb
  2. Your MB may only support 800 fsb So if when you look in your bios do you see a cpu multiplier option? Overclocking is a slow tedious process and if you do have an unlocked cpu then when you change the multiplier and Windows runs ok then you can use that overclock , if you want to go higher and Windows becomes unstable you have two choices , one is to go back to what was stable and the other is to add more voltage. The thing with adding voltage is you have to do it in the smallest increments as possible untill Windows is stable. That is why I said overclocking is a slow tedious process. Adding voltage is where you can damage your cpu if you are not careful. Before doing any of this I would try to get as much info as you can on oferclocking , a good way to start is to google "overclocking cpu".
