Monitor not connecting with new motherboard.

[kruizer]

The other week someone gave me a year old emachine T2682 with a fried motherboard. So I bought a motherboard to replace the old one, I got a Biostar P4M80-M4 Socket 478. I took the old motherboard out and put the new one in, got everything hooked up right and connected everything. When I went to turn it on, it turns on but nothing shows up on the monitor... I am not sure if its beeping or anything because the dang thing doesnt have a speaker.... Currently I am using the onboard video and it also doesnt work with a video card... I replaced the power supply with a new one and tried a different monitor and still nothing... does anything have any advice on what else I should try swapping out?

Thanks in advance

Update...
I took a 512mb stick out of my main PC and put it in the e-machine and the motherboard still doesn't turn on... could the CPU be bad? or is the motherboard just dead? any ideas?

That certainly sounds like a CPU problem. You've already replaced the motherboard, RAM, and video card. The only other things that could be preventing a proper boot sequence is the CPU and power supply.

edit: It is also possible that one of the standoffs for the motherboard is not connected properly or something else is causing a short circuit. Try taking the motherboard completely out of the case and install the CPU and RAM outside the case and see if it will boot there. If it does, then it's something wrong with the way the board was installed in the case. If not, I'd try a spare power supply then look at replacing the CPU.

Tried taking it out the case... same thing.. fans turn on and no video

I guess I will have to find someone that has an intel and try that out... or just pick up a new one sometime soon, atleast celerons arnt too much lol.

Thanks for the help

Have you tried resetting the CMOS? Is the ram in the first slot (some on-board video won't work unless ram is in socket1)? Any jumpers to set on the mb?

I have already tried clearing the CMOS by removing the batttery and by the jumper, neither worked . I tried the ram in both slots one and two. I couldnt find any jumpers that needed to be set for the video unless I am missing something. =/ Thanks anyways though.

Your mobo should have a connector to connect mobo to case speaker.
Disconnect everything from mobo - and this will narrow down the problem to cpu/mobo/psu - and disconnect everything from the psu.

Only reconnect the following to the mobo:
psu and 4 pin plug to near the cpu
CPU +Fan
Mobo speaker.
Touch the power button header on the mobo to start - any beeps?
