Overheating / Powersupply Question

Hey All!,

I've been having a problem with an AMD setup using a Gigabyte Mobo with a VIA KT400 Chipset. The CPU is an 2000+ (about 10 months old)
I've got an Enermax 431 watt PS


About 6 weeks ago, the CPU suddenly started getting much hotter on average... around the 49-51C range just sitting idle. Previously it had been around the 40C range. Also, I'm using a ThermalTake Volcano 7 and it was doing around 40C with the fan on low setting... now the fan is set to the high setting (~6500RPM) and it's still only keeping the chip down to about 50C. If it gets very warm in the house and the air conditioning isn't on, the CPU will hit above 60C and start to destabalize the computer after only 10-15 minutes of work. Most of the time it seem's perfectly stable (even for game play) in the 50-55C range.

I was goofing around with Motherboard Monitor this morning and noticed something really strange. My voltages are as follows:

+3.3 = 3.31
+5.00 = 4.93
-5.00 = ZERO!
+12.00 = 12.52
-12.00 = -7.68 and bounces to -6.82!!!


Is it possible that the PS is actually putting out these voltages? Could the computer actually continue to run like that? If so, could this be the cause of the CPU overheating? If the computer couldn't actually run like that, then is the sensor probably whacked on the mobo?

Help?

That's all within spec. The negative voltages are not used by current motherboards and most programs don't read them correctly anyway as you've seen.

As far as your temps, I'd check to make sure you case and PS fans are working and that your heatsink is not clogged with dust. Maybe removing the heatsink, reapplying some thermal grease, and reattaching it will help.
 
Thanks for the reply bozo1. I didn't know about the negative voltages not being used at all. I wonder why they are even tracked.

Thanks for the other suggestions also. Unfortunatly I've blown out and reseated, so there must be some other issue. 🙁

Thanks again,

Joe
 
have you tried re-seating the processor and checking your thermal paste to make sure it hasn't dried out? I've seen it happen, it's very rare, but in some really dry environments it does.
 
Yeah... don't all the basic stuff. I guess it couldn't hurt to do it all over again... give it a good cleaning and then a new thin coat of AS3.
