Wondering, if it is the motherboard failure

Hi.

Only thing what the PC I've got is doing after I've swiched it on is that CPU fan is working, I can open CD and DVD-ROMs and thats about it (no picture on screen). I thought it is a motherboard failure, so I swapped it over, but nothing changed. Any other ideas?

Hmmm

That hapened to me once, Turns out the processor burned out, and the motherbaord was messed to. The only thing you can do is bring it to a computer repair store so they can test the componants. Good Luck:(
 
do a bare bones boot. remove everything except the hard drive and one stick of ram. if that boots up, keep adding pieces one at a time. listen for the POST beep. if that fails, it is definately the motherboard/cpu.

no, thats not the only thing he can do. he's on a computer forum learning how to do that himself and save $100.00. do you think some 16 year old at best buy really knows anything more than he can learn here in a day of reading?
 
Hi. Thanks to everyone.
I re-described the problem and what I've done already. Basically when I switch the PC on, only thing what is happening is that CPU fan starts blowing and I'm also able to open CD-drives (that means that PSU is working and supplies electricity to MB and peripherals). Even BIOS wont boot up. Tried different AGP graphics card - nothing. So first thought was that MB is faulty now. I bought new MB, took old one out and put new MB inside the case and plugged everything back (so all cables are checked). Meanwhile I tested this HDD inside other PC and it was working. The new MB is with onboard graphics (didnt plug AGP-card on) and everything else plugged in, swithed the power button and result - nothing again. Wont boot up even to the BIOS. Then removed HDD, floppy, swapped over RAM and no result. I also used multimeter to check the voltages what are coming out from PSU and going to the MB, everything seemed OK.
Now questions: Should I be able to get something to boot up if I remove HDD, floppy, RAM and CPU. So basically its just bare MB. Or do I have to plug something in to get the first boot? How about CPU, if this is burnt, should I be able to boot up to BIOS?

Regards,

Kirret

I was thinking of the places that have like diognosticks (how do you spell that lol) for hardware. But you're completely right about the best buy people lol.

Kirret, I doupt it that you can go to BIOS without a processor at least. Did you try using a different processor, if not it might be the processor that messed up.
 
I trird to replace the PSU, but no luck. So I'll try to get another Socket A CPu and I'll let you know then. Thanks anyway.
 
Uh, not positive here but if it's a new build, some boards come with the "clear cmos" jumper in the "clear" position. You may want to check that.

sounds like its your cpu trouble is there expensive so see if you can put your cpu into a mates pc first make sure they are the same socket
