No video from newly hatched Frankenstein

By WaveStorm ·
I'm putting together an Athlon 850 system from parts -- my second building project.

All components except the monitor are very new: untested and uninitialized. There is no readily available second system that I can use as a testbed.

Motherboard: Gigabyte Slot A, no audio, no video
RAM: 256mb
H Seagate 20gb
Video: Pine TNT M64
Monitor: an ANCIENT Acer UVGA 14"

The monitor is old, but works fine on my laptop and other systems. All other components are fresh out of the box.

Problem: I'm not getting any video output. Nothing. No POST, no BIOS. Nada. The onboard speaker outputs nothing - no beeps.

Any suggestions?

My first guess would be that you have either a power problem or a montherbaord problem. There is a slight possiblity that it is a processor or monitor problem, but I suspect one of the first two.

Since you are not getting any POST, are you sure the system is powering up? Does the fan on the power supply spin up? Does the hard drive spin up? Do any of the diodes on the mother board light up (assuming there are some)? do the voltages of the power supply you are using match the voltages of the motherbaord/processor?

If you are absolutely certain that the power supply is doing it's thing, then look to the motherboard. Remove and reseat all components. Make sure there are no bent pins or damaged connectors. Be certain that the memory is seated correctly. Be absolutely certain that the processor is installed correctly and that the connector fits snugly.

If you have done all that, and you still get no indication that the system is trying to boot, I would do my best to exchange the motherboard -- or at least get the person who sold it to me to throw it on a bench and verify that it runs POST.

humbly submitted,

Thanks! The answer, as it turned out, came from the manufacturer. It seems that PNY memory has been known to cause problems in their Slot A systems. Thanks anyway!

Cheers,

Make sure that the video card is fully seated in the socket. That has been the number one cause I've seen for no video at POST.

Next, if your RAM is a single DIMM, I would try using a smaller size DIMM, just for a test.

Also, make sure the DIMM is in DIMM socket 0/1, as some MB require that socket to be used first.

Finally, is your CPU a classic or a T-Bird?
I have seen Slot A MB not post with T-Bird CPUs.
If it is a T-Bird, try setting the CPU core voltage manually, and see if thathelps.

T-Bird CPUs are only guaranteed to work with the AMD 751 chipset, and don't always work with the VIA chipset.

Check the Slot A board to make sure it is seated properly
Check the memory and seat it securely
The video card may not function with the monitor considering it is not SVGA
Check the power connections on the motherboard and also the switch on the back of the Power Supply
