Voltage problems with Motherboard

Hello: Just recently I have been getting a problem when booting up. I get
promted that there is a hadware problem. It says it can be found under
power, hardware monitor.

When I go into the bios and look under power I see one of the voltage
indicators is red, I imagine indicating the problem..It says its 2.8 when in
the motherboard book its show 3.3. I have been getting random freeze ups
with the computer as well.

How to I fix this? Is there a jumper or something I need to change?

It reads like this.

Vcore1 voltage
+3.3V voltage....2.8 <.............in red.

thanks.

You'll need to post specs about ur PC.. at the very least the
motherboard/cpu model and details, and preferably power supply rating (e.g.
300W, 400W, etc) and video card make model, etc. It would also help if you
told us anything you may have added or changed recently (video card, extra
drive, etc).

Once we know a little more we might be able to help.

Chris

There is no jumper to fix this, nor any "setting".
You need to determine if it's only a bios glitch (not
likely), a motherboard hardware failure (more likely) or
general power supply inadequacy and/or failure (most
likely).

Take voltage readings at the ATX connector with a
multimeter. Particularly note the 3.3V and 5V readings. It
might be that your 12V reading is even a little on the high
side if it's due to insufficient capacity.

Mentally reversing the following image will show the pin
positions to which you'd use multimeter probes to measure.
Of course system must be on, in the "problem... 3.3V"
state."

IF the voltage on the 3.3V pins is pretty near 3.3V,
contrary to the Hardware Monitor bios readings, it would
suggest that the motherboard, not power supply, is the
problem.


I'd advise you to not use the system, not have it turned on
except for taking the voltage readings until this is
resolved, as it could be damaging to data or hardware.

An alternative might be examining the motherboard for any
signs of trouble and if none are found, replace the power
supply with a decent name-brand with suitable wattage....
it'd be preferrible to take voltage readings first though.
 
Hello.
Asus A7A-266 motherboard
Geforce 3 vid card..visiontek
512mram ddr ....generic
350W power supply..generic
WinXP Pro
DirectX 9.0c

Thanks
 
I recently bought some RAM..apparently it is High Density and my motherboard
only takes Low Dens. When I tried it, it didn't work. So I put my old RAM
back in. Could this have caused the problem?
If it did, what would it do?

It shouldn't cause permanent (that is, persisting after that
memory was removed) problems.

Typically doing so would cause either a fraction of the
memory to be seen, none of it seen and board not running
(till removed) or at worst, instability causing corrupt bios
settings. You might try clearing CMOS and flashing newest
or current bios revision to the motherboard.

Those are not the common cause though, most often such a low
voltage reading is due to a power supply problem.
