For all the overclocker experts out there.. PLS HELP!

So I overclocked my Core 2 Duo E7400 processor. It's 266MHz and 10.4 multiplier. u can get 2.8GHz. Now, when I change the value of 266 to 276, I tried to reboot my system, it successfully rebooted. Then I went back to BIOS, I changed 276 to 286, I tried rebooting again, great, again it successfully rebooted. Notice that I change the value by the factor of 10. Then I went back again to BIOS. I changed 286 to 296... That's the time when my problem occured. My PC won't turn on. I mean when I turned it on, the fans turned, the CPu ran, but my monitor only says "Check the signal cable" then the light turned to yellow-orange. What's the problem here? Is it my power supply? Did I push my PSU to its limits? I think it's not my video card because the problem is regarding to the processor. I can't think of a solution so will you please give me one?

Any help would be much obliged!

You pushed it too far... You're supposed to stress each jump using a CPU stress test program (Prime95, OCCT, Intel Burn Test, etc.) You're going to have to pull out the CMOS battery or move the CMOS jumper to reset the BIOS settings. Look it up on google for steps as to how to do it.

Most likely pushed the processor to far on too little voltqage you need to reset the bios.

ya this is simple to fix, simply reset your cmos and start from the point where you know its stable, for my rig when I push it past a certain point and my monitor doesn't get recognized, I simply unplug the power cord and leave it unplugged for like 10 seconds and replug it into the wall socket afterward.AzNs3nSaT1On

I do the exact same thing lol, I don't know why people even bother resetting the CMOS, just leave it unplugged and it resets itself.

That doesn't work for me. I did that for my e4500 back in my first build, and that didn't work. It doesn't work for this build either. I left it unplugged for 45 minutes re-seating everything in my computer, and the settings were still there. The most definite method to clear your CMOS is to unplug your CMOS battery or use the CMOS jumper.

+1. The CMOS battery is there to prevent BIOS settings from getting wiped when there is a power outage. Unplugging the system won't clear the CMOS if the battery still works.

Reset your bios. This may be easy or hard depending on your mobo model. Mine for instance has a big red reset button on it.

May I point you in the direction of forums dedicated to overclocking?

I'd say that you went a bit too far if you're using a stock cooler and if you want to overclock further either get a better cooler or go into the BIOS and allocate more voltage to the cpu. Then again you don't want to fry the cpu by overheating it so i say go back the previous point at which it ran with decent stability after overclocking. When it comes to resetting the BIOS, for me, I can press one of the f_ keys ( can't remember which one) and it just resets all the settings. Also check your cpu temperature once you manage to get the computer to run again, if it's anything over 70 at idle i'd say turn it down because you'll fry it!

I also think you went a bit mad for it.

Overclocking isn't just jump in and hope for the best.

I do hope you read up and get properly equipped next time you try

Definitely replace the stock cooler if you haven't already.

Hope you get it fixed as resetting the bios on some boards can be a bi-atch others like mine have a reset button.

Good luck...

Well, he doesn't necessarily NEED an aftermarket cooler. Sure, you will get higher overclocks with them, but you can still get pretty far with the stock cooling provided you stay under the max temps. I got my friend's e7400 to 3.2ghz, and it's running fine with the stock cooler.
