The most common mistake people make when trying to overclock the 775 cpus is they forget about the ram. Double-check that your ram divider (or ratio, as some mobos call it) is underclocking your ram. And if your mobo supports it, leave all voltages besides the vcore on auto. That should get you 3.4ghz pretty easy.

Set the SPD to 2.00B which is the lowest divider. That will keep the ram at a 1:1 ratio with your FSB speed. So if you set the FSB to 333MHz, the ram will be running at DDR2 667. Do this while OCing thew CPU, then go back to the ram and mess with it some more.

Edit::
You will also want to bump the NorthBridge (called MCH Core in Bios) voltage a little because of the 8Gb of ram. The default for the p45 chipset is 1.10v, but 1.20v is a nice voltage to run. it is not too high, and also works great for a 400 FSB - 445 FSB OC for most.
here is your entire bios for reference:

If you don't like resetting the cmos then overclocking is not for you. That button is every overclocker's best friend.
When you bluescreen, when does it happen? Before you're done loading windows? A few seconds after loading windows? once you put a load on the cpu? I ask because BSODs can come from TEMPS aswell as low voltage.
Another way to overclock is to up the cpu 100mhz, load windows and stress-test. If its stable for 5 min, reboot and up another 100mhz. Keep doing this until you fail/bluescreen the stress test, then kick the vcore up by 0.1v and repeat. Remember you are overclocking the ram too when you change the FSB so ensure you're running the 1:1 ratio (link and sync mode).
Let us know how far you get (ghz, temps, and voltage), and we can help out with the other minor settings and voltages to reach the maximum oc

Well every time I've overclocked I haven't even gotten to the password screen. That time I had to reset the cmos (I pulled the battery out since I don't know if there's a button or not) it didn't even post after the Gigabyte screen it restarted.

sorry, i've been spoiled by my mobo (two reset buttons

). For you, it should be a 2-pin jumper near the bottom-right of the board. Your motherboard manual should also say where (page 7, i've heard).
If you're having trouble with any oc settings, try my one-step-at-a-time method

i'm sorry to say, but you'll find it real tough to pass 3.2GHz.... right now im using my ASUS P5Q deluxe and am having a hard time stabilizing at 3.2GHz.. I used to be able to do 400x8 on my MSI P45 plat, but with this one I'm having problems. maybe you'll have to stick with 3GHz.
