fried motherboard?

[mark2000]

hi

As this is my first post on this forum I would like to say "hello!"

I have a problem, I have a old pc that I don't use much, its a amd 200mhz, 64mb ram, win 98, 10 gig hard drive etc...

I recently powered it up and the psu exploded and I was greeted with a puff of smoke and it died :(

So I ordered a new psu and installed it, I went to power it up and all the fans came on, all the lights came on yet it won't boot up!

I have cheked all power connecters and they are connected properly and I have tested it with a mutilmeter so I know the motherboard and all the other devices are recieving power.

My question is this,

Have I fried the motherboard? if so, can I tell visually? Will there be burn marks? can you fry a motherboard with no visual confirmation?

these are the symptons

It powers up
All fans are powered and working
all leds are on
there are no beeps ( no post test)

it just sits there!

usually I would just try another M/B to see if that works but I don't have a spare one and I don't really want to spend money on a new one for a old pc unless I'm sure its the motherboard.

any help would be great, thanks

Can you clear CMOS? If you can find the jumper---and there's probably a lot of them on there---on that motherboard, try clearing it and see if anything happens.

If the motherboard is dead, and one little component died, you'll have to look very hard to find it. I would look for any capacitors (those cylinders pointing upwards) and see if they're leaking.

If you see any scorch marks around the power supply connector on the motherboard, that can be a cause for alarm.
