Info: Ways to tell you have a fried motherboard.

post #1 of 13
Thread Starter 
I have now fried 3 motherboards, possibly 4, and have decided to write this since there is none to show signs of motherboard destruction. I will also give a few examples which are sure fire ways to fry your motherboard (I have experiance with the examples

No signal on monitor has been shown in many threads to usually be something missing, or PSU broken, or video card broken, and sometimes motherboard. If fans run or LEDs turn on, and it says no signal, it probably isn't power supply. First rule of thumb is to always test things if you can. Video card usually isn't the problem, I have only fried one video card and it was a bad one. A helpful hint I got from the DUKE is to take your motherboard out put it on a non conductive surface, put in the bare minimum for turning on (one stick of ram, on board graphics instead of video card if you got em, no hard drives or cd rom.) This will ensure basic to rule out other things. If you still have no signal on monitor after checking all connectors, could be video card or motherboard. Hopefully you can find someone to let you test your stuff on. If your computer jsut turns on then restarts instantly. It could be an overclock if you hadn't figured it out already. In which case clear the cmos jumper. In your motherboard book it should say where it is, it is usually near the battery though. If your motherboard doesn't have a cmos jumper, take out the batter for a few hours and when you put it back in it should be fine.

Some ways to fry your motherboard...

1. Don't use the supporting screws that go on the case that the motherboard screws screw into, just screw the motherboard into the case, this will fry your motherboard.

2. Don't plug in the 4 pin molex extra plug in your video card (if you have one), then turn on computer and wait for small strand of smoke to come up from video card. This will fry both your motherboard and video card surprizingly.

3. When cooling your northbridge, don't put AS5 on just the core part, put it all around the core, even on the little rubber circles to keep the heatsink off plugs, this will fry your motherboard.

I admit reading this isn't a very detailed guide and I apologize for that. Hopefully this will give some help though, if anyone has anything to add I will.

Also, on boot-up, it hangs. I have the AI7, and it displays a POST code in numbers, and it hung on a number. I RMa'ed it, and they confirmed it was dead.

hahha that stinks about the screw. I really wish my first FAQ could've been better the more I look at this the more I feel I did a bad job. What do you guys think?

I didn't plug in the 4 pin molex to my video card once and turned on my comptuer to find a message on the screen telling me to plug it in. LOL I just plugged it in and it worked fine.

Like Tory, I forgot to plug in the 4-pin to the agp card. Only problem: sort of crashed on launching any game. Everything else worked fine... (?)

The video card slot (agp or pci-express) doesn't provide enough power to newer video cards. If you don't plug in the extra molex (or 2), you're starving the video card of needed power and bad results can follow. I've done it once with an MSI board and an Nvidia 5900, but nothing was harmed. I've also forgot to plug in the PCIX connector on my x850xt before, but again, nothing fried thankfully!
