Upgrading Motherboard

**MadDog** · December 16th, 2002, 11:01 AM

Went to upgrade my motherboard, CPU and memory the other day, and had some weird problems. As far as I know, I did everything right. I disconnected everything off the old motherboard (an ASUS K7M), put in the new one (A SOYO KT-333 Dragon Lite), hooked everything up, and powered it up. The HDD light stayed on all the time (the cables were correct), the power light never came on (wire was correct), and no video output. This happened on three motherboards. Same symptoms. Luckily, the place I bought them asked no questions when I returned them. After returning the second motherboard, they checked out the second motherboard, and it was dead. The place hooked up the third motherboard to a mock-up, and got it to POST, with video out. Being extra careful, hooked it up, and had the same symptoms.

The old motherboard worked fine when I put it back in.

What did I do wrong ??? I've done the same thing for friends a bunch of trimes, with no problems....

Tried a new power supply?

Tried hooking it up with no drives connected at all just ram and video and the hdd led disconnected?

Tried that with the third MB. Still the same. PS is 300W, which should be more than enough. Plus, it works with the old MB.

Looking for possible explanations of how I smoked three MBs !!

Maybe you left a stand-off in the wrong place.

Shorted the new board?

That's what the store thought, after the second board. But I triple-checked for the third board......

So, the question is: Should I try again, or has my luck run out for the rest of the year ???

How about taking it to the shop and putting it together infront of the tech there, have him check you as you go?

That's probably not an option, as it's a big store, and they're not really set up to do that.

Any other reasons can you think of that I may have done wrong (other than the stand offs). ???

That's what the store did for their mockup. Yes, the fans turned all three times.
