I was looking in my Asus PC Probe program which I have not done in a while. After a few moments i get a blinking warning saying "+3.3V Out Of Threshold!" It hasn't done this in the past. I am wondering if anyone knows what is causing this problem. And what cord does the 3.3v apply to? Also is this doing any harm to my computer at all? Thanks in advance to whom may help. ____________________________________________ AMD Athlon XP 1800 ASUS A7V333 IBM 80.0 GB HD 256 DDR 333 Geforce3 Ti500 XP Professional + SP1 350 watt Power Supply No overclocking on any hardware ____________________________________________

3.3v is the voltage of most modern memory modules and cpus, so it can be costly to continue operation. If you aren't familiar with power supplies, then I'd suggest that you have a qualified person check it. Power supplies aren't that expensive now, but new boards and such are. If you have an electronics background, then you can check the output of the power supply with a quality digital multi meter to see if it is out of range (the min and max values would be displayed at post or in the bios options) or if you've got a sensor malfunction or something. The 3.3v wire will be color coded and should be marked on the power supply housing. If it's just a bad sensor on the board, that can be disabled in the bios, but check the power supply.

What do you mean check the power supply and why would it all of a sudden start happening? Also i have noticed my computer hangs sometimes now would that me a symtom of it?

Most hardware failures occur at the time they are powered on in electric circuits as this is when the potential difference is at it's highest, so the symptom would appear all of a sudden. Depending on your motherboard (I expect yours to be an AXT board) there is a connector coming from the power supply that connects to the motherboard. ATX forms will have a 20 pin connector that is rectangular and it has two rows of 10 connectors. You can insert the probes of the meter (pos [red lead] into the appropriate wire and neg [black lead] onto the case ground or a black colored wire from the power supply) The case must be opened to do this. I would not recommend that you attempt to check it if you're unfamiliar with electronics as you can destroy your equipment. Hanging can be a sign of memory failure which would make sense if your power supply were flaky. HTH
