Overclocking failed My PC restarts spontaneously even if i am not doing any work on it and says 'overclocking failed'.I tried changing power supply but it wasnt of any use.The BIOS setup has Overclocking on Auto mode.

Also, make sure its not on a gfci circuit. Even if a gfci is after the TV, like outside on a deck, a power surge may have damaged it. But that would most likely mean nothing in the circuit would work.

LOOK IF A BIOS PASSWORD IS SET.

It could be a marginal power supply, gaming puts more requirement, processing power, therefore more power is required by the CPU and the graphics card. And of you are overclocking then it needs even more power and generates more heat.
If you have a dedicated video card installed you should have a 550W power supply.

that is blue screen of death due missinstallation of hardware or software or any changes might took place. try installing a fresh operating system and hope it should work

You can test the PSU (PC Power supply unit) using a multimeter, then eventually replace the power supply.

1: You problem is your power supply, PSU. When you try to give more power to your CPU by overclocking it, it doesn't have enough wattage, or power, to get the CD drive, or your sound card to work. This is why the CD drive works again when the CPU isn't overclocked. So, in this case, to overclock your CPU, you would have to get more power to your system by getting a more powerful PSU, or one with more wattage. How much you can overclock your processor depends on a variety of different things. Your RAM, PSU, HDD, CD drive, etc. I would not go past about 3.4ghz with your processor, however, a "max overclock" is hard to determine.

2: The maximum temp for your processor is 70C, 158F. I would try to keep your temperatures under 60C to ensure your processor doesn't "die early" on you. The multiplier cannot be changed, only the FSB can be changed. You should be able to create a "profile" in bios and set it to your default so that it loads up automatically when you boot up. Make sure you find a stable configuration before you make a default profile.

some mothere boards do not alow over clocking its bes to ask where u buy the mother board / cpu if it is posible to overclock

@johnhercus26
pls let me remind you that overclocking voids your pc's warranty.you will need to enhance the cooling solutions for the device you will overclock plus the cooling solutions for the CPU case, every time you overclock, more heat is produced by the device you are overclocking. also you have to make sure you have power headroom..., a higher wattage CPU power supply. plus the risk that you may toast your pc or lessen its usable life. overclocking is for advanced users so pls take extra caution if you will do it.. for guide and instructions pls click here and goodluck! >>> http://www.pcstats.com/articleview.cfm?articleID=1804

Sorry my friend but Dell doesn't support overclocking.You need a new motherboard and power supply and a better cpu heatsink to overclock your Dell. You would need extra fans too. They lock there BIOS settings as far as 1:1 clocking to prevent troubleshooting issues and they want you to buy something faster if you want something faster. I don't know how old your machine is but any attempt at overclocking would also void the warranty. They even recommend using just one brand of memory even though there are many that would work.

It sounds like you're trying to overclock your CPU, and you have exceeded what the CPU is capable of, under the current conditions. When you start the computer, enter BIOS setup (e.g. press the DEL key), and adjust the CPU settings to default. If you're not sure how to do this, choose the "LOAD OPTIMAL SETTINGS" or "LOAD DEFAULT SETTINGS" option from the main BIOS menu. If you are not getting this error until after Windows has started, then there is software installed that is trying to overclock the CPU for you. Uninstall it. It may be a program provided by Asus, or may be a third-party program. It will probably have "tweak" or "overclock" in the name. Overclocking can achieve an increase in performance, but will void the warranty, and does reduce the lifespan of the parts, and tends to make Windows crash more often. It can cause immediate failure of the parts. It should only be done if you understand and accept the risks, and have decided the reward is worthwhile. For most users, it is not worth it.
