I tried to overclock my AMD Phemom II X4 955 about 5 minutes ago. I changed the multiplier to 19x and voltage to 1.5 like I saw in one of PCWizKid's videos.
Now when I turn my computer on, nothing shows up on my monitor, and my keyboard and mouse don't come on.
How can I fix this? Please help quick!!!
wow you might have cooked something If it is dead you might have fried something never try to duplicate someone else's specs just because they got it there doesn't mean you can do the same
cooling proper voltages and testing are the only sure fire ways to assure the overclock is certified and when you oc too much and this happens might not be a way to come back from that unless you got lucky and just damaged the board and nothing else
Im sure other posters will recommend some device testing before rulling out any possibilities
ps sorry i didnt ask this before does it even boot up ? I know you said nothing shows on the screen but does it even make a attempt to do anything plus do you have any access to the Bios at all if so i suggest you get on trying to tone it down and it might come back
Isn't there something I can reset? I thought I read somewhere that resetting the cmos will restore the old bios's settings. How can I do that?
Pull out the little coin battery on your mobo, and put it back in. If you can get back into the bios, load the defaults settings again.
yeah you can reset the cmos with the battery but if your board is like mine you might have a switch on your board to take it back in case this happens I dont know what kind of board you are using but just in case before resetting the cmos
look for a reset switch and they should also have a debugging switch as well in case such a thing occurs
but like i said read what type of features your board has
Download your manual from your motherboard site>then check for a CMOS jumper> to reset the CMOS on most boards all you have to do is move the jumper over to the next pins. unplug your system let the capacitors fully discharge then replace the jumper to the proper settings.
This will reset your bios to default. If you can't find it or your board dosen't have one then the battery trick will work.Fabe http://download.ecsusa.com/dlfileecs...AD3_manual.pdf did a quick read through didn't see them pointing out CMOS reset but they have extensive information on using your bios I would suggest you read throguh before you attempt another overclock.
Read through some of the other threads on overclcoking before you attempt to do so,never just use something someone else has posted as even the exact same setup will overclock differently. It's not a simple process and can easily brick you system.

Once you get the bios reset, you should be able to boot again. (hopefully)
Before you start trying to OC agin, please keep in mind theres a few things you MUST know before doing anything.
1) How to reset your Bios in case of failure is the first. Sadly you're learning this the hard way.
2) What your bios settings mean, and what effect they have.
3) your Hardwares Temp and Voltage ranges. Where is safe, and where is dangerous.
4) Something more than stock cooling is important.
And as mentioned, do not try and duplicate someone elses settings.
There are just to many variables as to what will be stable on what system. Unfortunatley, not all hardware is the same, even if it is technically identical.
Meaning, someone can have the exact same set up you do, and still get slightly different results. Sometimes better, sometimes worse.
If you want to learn to OC, do alot of research first.
Then start slow and be cautious.
Wishmaster has give some great advice. I would add before you ever overclock, cooling, cooling and more cooling. A couple 10ths of a volt can really raise you temperatures a lot. There is no such thing as to cool of a computer, temperature wise.
