Low 3.3 Voltage, frequent reboots

[darktyco]

I've been experiencing frequent reboots with my PC lately, but I haven't added anything new or overlocked anything. The only possible suspect I have is Asus PC Probe reporting that my 3.3v is hovering between 2.7-2.9. Could this be the problem, and if it is, what do I need to replace, the motherboard or power supply? My components are:

T-bird 1200
Asus A7M266
Addtronics 300 watt PS (2.5 years old)

Thanks in advance!

You`re right,the problem is that power supply.It is the i/o voltage and if it gets lower your system may have boot or reset problems.

A 300watt PSU on the T-BIRD is pushing the PSU to the limit.

Low-voltage is bad. That reading really should not be lower than 3.2volts.

Remember also. Anything else you have plugged in along with your Computer on the same circuit
will lower the AMPERAGE to the PSU.
