System Reboots Due to PowerSupply. Is this Possible?

[kineticdesign]

Is it possible for the powersupply to reboot the system? I've heard of powersupplies fluctuating, and mine is about a year old. If it doesn't give enough power, will it reboot a system?

My system keeps rebooting in windows, over and over, and the powersupply makes that click and "power up" sound right when the system restarts.

Is it possible for the powersupply to do this?

thanks

I had a problem where my system would spontaneously shut itself down and restart. I thought it was a bad p/s until once I noticed that Windows put up a "System is shutting down" notice (for a fraction of a second) as though I'd hit the power switch on the case.

Sure enough, after I removed the switch the next time it powered on, the problem vanished. Picked up an ATX power switch for $4 the next day, worked like a champ ever since.

May not be what's going on in your comp, but you might try disconnecting the switch from your mobo just as a test.

Very possible and very common.

not with atx powersupplies it isn't. actually you have a bad power switch on the mobo, replace your mobo and the problem will go away.

Take a look at my recent post a few days ago. I was having this same problem when I was trying to shutdown my PC, but instead it would reboot. I would get the same clicking sound llike it was going to shut off, but instead it rebooted. Turned out to be out of date drivers for my Logitech keyboard & mouse. Who'd a thought? Check the thread. Is there any blue screen falshing up before it reboots? If so follow, follow DAPUNISHER's recommendation on the thread, which is what lead to my reolution.

I've run into that situation and thought it was the P/S. Through a process of elimination I found out it was a bad MoBo. If you have another P/S try that and see if you can narrow it down to the P/S or the MoBo. My money's on the MoBo - especially if it's a PC Chips.

Top reason's fer a computer to shutdown/restart randomly.

Power Supply - a bad (or insufficient) power supply is the most common cause for random crashes, especially if you have a lot of cards, drives, or fans, or have a dual-processor motherboard. A 350W or 400W power supply is recommended if you're experiencing this problem.

A mix of FAT32 and NTFS drives - If you have more than one hard disk, and there are different file systems on each one, try converting them all to NTFS.

Audio Card Drivers: - try removing your sound card, or at least uninstalling and then reinstalling the drivers.

USB Hub: - if you have a USB hub, try eliminating it and see if that solves the problem (especially if you have a USB-based Palm cradle and your system crashes every time you hotsync).

Overheating: - a computer will crash if the processor overheats. Make sure the CPU fan/fans are working, and that the processor temperature (read in the BIOS screen) is within normal limits. Make sure your computer case has adequate ventilation.

Bad memory: - a bad memory module can cause this problem. Try removing one of the modules (if applicable) to see if that solves the problem; rotate through all modules until you've found the culprit. Note that some computers require memory to be installed in pairs, so, for example, if you have four modules, you'll have to remove two (no more, no fewer) for this test.
