Strange problem... voltage dropping

[outsiderGT]

Hey guys,

My 2 year oldish system is acting up. My ASUS PC Probe is complaning randomly when the +12v and +5v drop from time to time... this has never happened. Also, my mouse and entire PC will kind of "freeze" as I try to move the mouse across the screen (all operations kind of "halt" for a second) and then resume normally. What could be causing this? Faulty power supply?

sounds like the power supply might be going bad. I would try a new power supply.

You could use Motherboard Monitor 5 to monitor your voltage rails. There's a "syslog" feature that allows you to record readings to a text.doc over an extended period of time. Go back and view it after you notice problems to see if it's psu related.

Hi, I am having problems with my PC, after 2 days with my PC powered off, when I tried to power up, all the lights come on to all the devices ... I have 2 CD-Roms(both are burners), 3 HDDs(2 SATA, 1 IDE), 2 512k of Ram, Intel 2.4C 800 CPU, Video Card, Sound Card, Wireless card, TV tuner, and 420 Watts PS, the case has 8 Fans connected. I built this PC myself, but this seems an on going problem. It only happens when my PC is turned off for a day or two, and when I try to power up, its seems the system is hanging. All the power lights are on, the HDD lights are on but I don't hear them spin, and I don't get the POST, nor any signal to the monitor to show anything at all. But when I disconnected all the devices and left only the CPU, videocard and ram in, the lights come on but no signal showing on the monitor. When I connected at least the 2 SATA HDDs, I get the POST and I can boot to CMOS, and OS. I am not sure why this keeps happening, I tested all the cards, and CD-Roms, and they seem to work fine. I am wondering if its the power supply or the Mobo? I purchased this mobo from ASUS, the P4C800-E Delux, so I don't know if its one of the chips. It would be kinda sad to know if its the mobo because it was a costly purchase. I was thinking of try getting a Power supply tester. Any ideas would be helpful, I've already tested the PC with a different monitor, reseated the CPU, RAM, and reconnected the devices and everything will work fine until I shutdown and don't use this PC for a couple of days. Really wierd.
