Try to remove power supply cable from motherboard, now you can remove battery in 5 to 10 minutes its depend on your mobo.Also try remove cmos jumper or read your mobo manual on how to clear bios to default settings.And if you have no knowledge on how to overclock dont do it sometimes it can cause permanent damage.

If you have'nt got your mobo name,the only way to obtain it,is look inside your mobo and see if there big text written in large font,this can be betwen cpu socket and ram slots or look around that area.Or if your system is brand like hp or dell there is a name outside of the case,front area of the computer case.

Have you try to remove power supply cable and remove cmos battery?Psu cable has 24pins that pluged into mobo.Try to locate your psu then follow the wires and unplug them.Also there is 4wire that pluged near cpu remove that too.Your mobo manufacture is intel,what i need here is full name of your mobo.If you can't find it there is another way to locate cmos jumper try to look the area were you found cmos battery there should be a jumper with 3 or two pins this jumper is similar to cd rom or harddisk jumper.

You do NOT have to disconnect the 24-pin main ATX plug from the motherboard. Just make sure that the power cord is unplugged from the wall, then move the jumper from pins 1-2 to pins 2-3, wait a few seconds (not minutes), then move the jumper back to pins 1-2 again. Plug in the power cord, boot up, enter the BIOS & correct the settings. And don't attempt to overclock again until you learn how. Changing the RAM timings really isn't overclocking anyway & from the looks of your RAM description, you're not running dual channel mode.

"i have dual channels one channel is 1 gb ddr2 and the second is 2 gb ddr2"

Dual channel is a function of the board, not the RAM...to enable it, you need to have the correct RAM (matched pair) installed in the correct slots. If you have a single 1GB + 1 single 2GB, you're probably not running in dual channel mode. You would need 2 x 512MB + 2 x 1GB to be able to run 3GB in dual channel.

Post your complete specs...motherboard make/model, which Core 2 you have, which DDR2 RAM (533, 667, 800, etc), which video card, power supply etc. If you wanna overclock, I can suggest some settings.

The HD4650 & HD4670 cost about the same, go for the HD4670. If you go with any of the others mentioned - HD4770, HD4830 or HD4850 - you'll probably have to upgrade to a better power supply, that'll cost at least another $50.

Hey e4400 is great cpu 4 overcloking,first thing monitor you temperature before OC,go to bios make sure to disable spread spectrum,EIST aka speestep,cpu enhanced halt CIE.And lock pci express at 100mghz,lock pci at 33 or 33.33mghz.I think these options can be found in main and advanced menu.Your cpu fsb is 800/4=200mghz,your memory run at 667/2=333mghz and your cpu multiplier is x10 running at 2.0ghz use cpu z to check it.Lets push to 2.4ghz by increase fsb to 267 and decrease multiplier to x9.These settings can be found in main menu in the bios.Save changes and exit,if pc failed to boot reset bios.If succeed to boot check cpu temp.
