Challenge? No video signal - ATX form

By rw1 ·
Brought a PC home from friends house to add RAM. Using my monitor after replacing RAM, I now can not get a video signal.

Thought it might be flaky power supply, I replaced power supply.

Tried a previously working card, new card - all fourPCI slots. No signal - Monitor is good on another PC.

I have unplugged all boards, connections except for floppy and CPU fan and video card.
Reseated many times.

Could it be my VGA monitor (Impression 7) may not be compatible with friends video card?

Any ideas?

Make sure the RAM is seated firmly. You will not get a display if it's not. Is the hard drive spinning up? It's possible the Motherboard was shorted when intalling the RAM. Try removing the RAM you installed and see if you get a display.

You may have made a mistake in putting EDO memory in an Fast Page system, if this is an older computer. I've done that myself once. If that's not it try removing the cmos reset jumper and try rebooting.

Mobo specs say either FP or EDO RAM can go in SIMM slots

Return the computer to its original state - lesser ram. If the video displays now, the answer is the RAM. Incompatible with the MOBO. All this assuming there is other activity like POWER? HD activity? Cooling Fan on? If there is no such activity, the problem is power related. Some times merely replacing the power cord (and they do go bad) fixes the no activity problem.

Good luck.

Didn't help - RAM might be bad?
Still trying other things.

Thanks,

I have experienced each of the situations in the 3 answers above. I have also seen the pins in the memory socket get bent by the sharp edge of a new memory strip. Remove the new RAM and use a magnifying glass to look at the sockets. If you do have bent pins, bend them back Slowly and Carefully using a small sharp tool (ex. dental pick). It sounds strange, but incompatible DIMM strips will cause same problem. We have helped several customers by changing to a different chip manufacturer for their computer. Good luck.

Using SIMMs - didn't look bent to me - thanks anyway.

Is there a NIC card in the machine? I have had an experience dealing with a NIC card going south which in turn caused a boot without video signal.
