Temps and voltages look good other then that tmpin2...what is that reading I wonder? Whatever it is, it's either wrong or overheating!

OK, looks like the north bridge temp, if it is correct, it could be the source of your problems...It's more likely that it's an incorrect reading, but is probably worth further investigation...I wonder of a heat sink came off or something. Those temps are hot enough to melt solder, so if it is correct, it could brick your laptop with continued use.

try this hw monitor to see if there is any diff:

Open Hardware Monitor - Core temp, fan speed and voltages in a free software gadget

Do you know which chip is the NB? If not, send me the motherboard model and I will tell you what to look for.

It is going to be one of the big chips on the MB...like a 1in sq...it should already have a sink, but some do not....

Your options are:
-verify chip is "burn your finger" hot
-add a sink
-re-thermal grease current sink
-replace current sink with larger one

Let me know what this investigation turns up.

Since the reading remains unchanged while the rest of the temps have highs and lows it's most likely not a valid temp reading.

The 3.3v reading if correct would also be suspect, boot into the bios and see if there is a hardware health page, on a OEM bios there may not be if there is check the readings for the NB and the voltage readings for the 3.3v, 5v, and 12v power rails.

Thanks for the replies, Deek. I'll run another hardware monitor test with the sw you pointed me to. At work, so results will come later.

The motherboard model is --> N-Alvorix-RS880 Motherboard

When I had the cover off the other day to switch memory, everything looked solid, nothing loose, amiss or whatever.

It's getting to the point of time to buy a new box. After yesterday's losses, spending much more time on a $450 3-year old box gets harder and harder to do.

Will do. Report back in later today.

Report from Open Hardware Monitor is attached. BIOS did not have any rail diagnostic information.

Deek · Sep 19, 2013

ok, so that report doesn't have that NB temp, I suspect that is ok, but it's hard to tell remote...you might want to get fingers on it...it should not be so hot you can't hold your fingers on it for a few seconds.

Also, there are suspect voltages....that report indicates 3.06V on what I believe should be the 5v rail....

Assuming you already checked the motherboard for bad capacitors, do you have another power supply you can swap in and run that same util so we can compare voltages?

I replaced the power supply in January with a Corsair 600w piece, mainly because the previous ps's fan was noisy. I tossed the old ps, so I don't have another handy. All the components on the motherboard appear to be in good working order, or at least nothing appears out of the ordinary.

Thanks for all the help guys. It was truly far more than I could have imagined. I decided to toss in the towel and buy new after putting in several evenings of troubleshooting with no luck. Another year out of a $450 3 year old computer would have been nice, but it did not happen.

Great forum, glad I stumbled across it, and I donated to the cause in hopes it is here for the next frustrated soul.

Thanks again,
Casey

Sorry we could not have found a definitive solution, stop back whenever you need to.

Thanks for the help, no need to apologize. Was a learning experience for sure.
