Motherboard hangs during memory check/POST

Hello,

I have a Gigabyte GA-8vm533 motherboard here that after having powersupply
problems, began having problems with posting after I replaced the power
supply. The system powers on and instantly goes to the memory count/test
part of the POSTing and hangs each time. I've replaced memory sticks, tried
different memory slots, same thing happens each time regardless. I even
press DEL really fast trying to get into the BIOS, however it still hangs.
Does this mean the motherboard has suffered damage from the previous failing
power supply??

I even tried resetting the CMOS settings but that did no good.

Help!

Brad

Hold on a minute...

Why is it assumed you formerly had PSU problems?
Is it now assumed the new PSU doesn't have any problems, is
suitable for the system, or are you only assuming it based
on some number on a label?

It would be good to start with a concise but complete list
of all major components, including PSU make, model, and 12V
current rating.

Beyond that, see if system is stable at lowest FSB/memory
speed you can set, and with only 1 memory module, CPU,
heatsink/fan, and the least power hungry video card you
have, preferribly PCI if available.

The PSU fan stopped working and it was becoming very hot. Also the voltage
rating was fluxuating outside of the 12.0 / 5.0 area, mostly dropping down
by 1-2volts when I checked it. I replaced the PSU with a new Antec 350 PSU.

The motherboard is a GigaByte GA-8VM533 motherboard. The PSU is a brand new
Antec PA350.

The system is not stable with any memory. I went through numerous memory
sticks of various speeds and combinations in slots, the POST hangs on the
memory test each time. Tried CPU replacing and that did not solve anything.

Ok, but since that's not a complete list we can't know if a
350W Antec is enough for the system.

Since you'd checked the former PSU I'll assume you have also
checked the new one and that it's voltages look ok.

Check the motherboard manufacturers website for bios updates
if the system had never been stable. If it had formerly
been stable and the only obvious change is that the old PSU
failed, there are a few things that come to mind, to suspect
and/or check.

Check for vented motherboard capacitors.
Clear CMOS
Double-check all cards, cables, connectors, to be sure
nothing was dislodged while pulling old and installing new
PSU.

Otherwise I'd suspect that when the old PSU was failing, it
might've damaged the motherboard or some installed part(s).

I'd try a higher wattage PSU if you have one available,
otherwise besides the aforementioned things you might try a
new motherboard.

Very possible. A PS gone bad can take out other cards and even part of
your motherboard. When PS supplies go bad they generally put out too
many volts.
