my computer won't start up after overclocking

jon_boy4ever · 05-13-2009, 09:34 PM

Specs:
Motherboard- ASUS P5N-D
CPU-Intel core 2 duo(3.16)

So I tried to overclock my computer without much research or experience. I figured out how to do it from a couple of videos, I can't remember the exact setting i had it at but it was something like AI overclock after picking that i could chose between 5%, 10%, 15%, and 20%. I set it to 15% and exited and saved the changes. The computer froze almost instantly on startup. So i restarted and went back to the BIOS and set it 5%. A thing poped up saying it was saving motherboard setting(or something) and do not turn off or reset your computer. After 10 hours it was still on that screen so i turned it off. I then attempted to turn it back on. All the lights turned on and fans started up but nothing ever came up on screen. The monitor just said no input. Any help would be much appreciated.

Try resetting you bios. Take out the battery for a few minutes then put it back in and restart.

Okay dumb question but do you know where the battery is or what it looks like on my motherboard. I know how to take it off of older computers but i didn't see anything that looked like what i was used to seeing.

It looks like a watch battery. It's flat and usually about the size of a quarter. It could be standing on it's side or lying flat on the mobo.

Ok, i found the battery it was cleverly hidden under the graphics card, but even after taking it out and putting it back in, it still failed to startup any other suggestions?

Ok then. At this point I would remove everything besides the video card and 1 stick of ram. See if you get it to post. Follow sticky by Linderman below for bench testing.

Odd that it seems that the Asus utility could have been used for a simple overclock....I wonder on the age of the Motherboard and why there would have been so much fuss involved in the start up after the O.C. I would have chosen the AI Suite for the overclock instead of the BIOS for the simple reason that once you use the feature well it shows up in the BIOS anyway just like it would if you had gone that route from the beinning anyway. I have had my system tell me that the overclock has failed when I first got the system which might have been cause by inferior cooling methods because ever since I have increased the amount of fans that I have Overclocking has been a breeze. I've had my system up to just over 4 Ghz for a couple of days and the stress testing has come back positive as well. The memory matches the O.C. Profile as well and that has been up over 1100Mhz as well. I'm not a huge advocate of Overclocking simply because the benefit might outweigh the cost depending on what you are looking at doing it for and only if you have sufficient methods to ensure thermal stability.

cmos reset
turn the computer off
remove the power lead from the back
take the side off
remove the cmos battery
move the cmos jumper from pins 1 and 2 to pin 2 and 3 and the back to pins 1 and 2
reinsert the battery
put the side on
replug in the power lead
boot the computer

there can be 2 solder points you touch with a screwdriver
2 pins you touch with a screwdriver or use a jumper
a cmos clear switch or button
there will be a diagram and instructions in your manual
