At this point, I have my doubts that your system was ever properly assembled as a complete system so I am going to go over all of the basics.

The proper way to apply thermal compound to a CPU/Heat Sink (clean surfaces with a quality rubbing alcohol) for AMD:
http://www.arcticsilver.com/amd_app...

If you feel that it is needed, you should be able to reset your NorthBridge heat sink, Google for directions or ask mfg for instructions (I have never needed to do this), but try all else first to make sure that something else below helps you fix things.

I notice that you only show one fan speed on HWMonitor, this probably is an indication of a problem to me. You should have ONE fan on your CPU heat sink pointed down towards the heat sink. You should have ONE fan high up at the rear of your computer's case set to exhaust (blowing OUT) to expel hot air from your case. You should have ONE or more fans on your computer's power supply that also takes air from the inside of the case, blows it over the power supply's components and then out of the case (as a supplement to the case fan). That is all you require for your case air flow. You CAN add (if your case allows, add a front intake fan low in the front of the case (blowing IN) as an option, but unless you have a powerful graphics card or multiple hard drives, this is not really needed. For cases with bottom mounted power supplies only, you can add another exhaust fan at the top of the case if there is a place for it if needed. << Never use side fans >>
You should have a continuous flow of air that comes in low at the front of your case, flows over your components and out high up at the rear of your case. Heat naturally rises so this natural convection adds to this process of removing the hot air from your computer's case. If you have stagnant air (not moving) or turbulence (moving in all directions, but not efficiently moving the air out), then you could actually be concentrating the heat in the one or two spots and not removing it.

For those who are not overclocking or mildly overclocking, the stock heat sink and fan should be sufficient if properly attached and maintained. I am running two systems overclocked (and others in the past) that are overclocked on stock Intel coolers and my temps are idle 30C-34C, mid 40C's normal usage, and max load low 50C's. I do however, run slightly improved case fans (high CFM's, low dB's) quality aftermarket fans usually $6. to $12. set up as above.
Closed loop water cooling systems would be a waste of money for you, they rarely perform much better than a higher quality aftermarket air cooler which will be less money, and those are really needed for more serious overclocking, especially when those overclocked systems are used for serious use like gaming or graphics and/or CPU intensive work environments.

You have to be a little bit crazy to keep you from going insane.

Please turn off the Caps Lock. All caps = SHOUTING.

It appears your system is overheating so how about posting some temps? HWMonitor doesn't just say HOT, it displays actual temp readings. Some of the most common reasons a system overheats are:

- improperly installed CPU heatsink. Could be it's not fastened securely or there's a problem with the thermal paste application - too much, too little, incorrect placement, or none used at all. The "middle dot method" should be used for all current AMD desktop CPUs:

http://www.arcticsilver.com/PDF/app...

- CPU cooling fan has failed, is failing, or is dust clogged.
- too many case cooling fans installed or incorrectly installed.
- Placing PC tower is inside a desk cubby or cabinet that allows for very little airflow.

Another possiblity unrelated to temps is the power supply. All you provided is the wattage. Please post the make/model/model number.

You have bad RAM. You're going to have to determine which stick is causing the errors & remove/replace it. There's no point troubleshooting any further until the RAM problem is fixed. But you can remove the bad stick for the time being & see if the other problems go away.

Memtest results indicate that one or both memory sticks are bad, BUT before you replace, get the temps under control to make sure that the overall case temperatures are not effecting your memory. A thorough cleaning is called for as well as giving us more details and results after your cleaning. Use a can of compressed air that you can purchase at a computer store, Office supply store, or your local Radio Shack (never use a vacuum inside of your computer's case) to do the cleaning.

The NB is the one in the center, just below the CPU socket, is that the one you suspect is overheating? You can't tell by touch, you need to find a decent hardware monitoring program that tells you exactly what is what. See response #8.

http://elitegamingcomputers.com/wp-...

If the NB needed a fan, Gigabyte would have installed one. You didn't remove the NB heatsink for some reason, did you? Have you messed with any of the BIOS settings? Have you disabled the Win7 auto-restart feature?

Frequency does not generate as much heat as voltage does.
If you are not overclocking, reset your BIOS to defaults, then manually make sure that your CPU, Boot drive, boot order, Graphics, memory settings, etc are set correctly.
Make sure that your voltages are all set to Auto.
Report ALL temps, voltages, fan speeds, etc in HWMonitor

The CPU temp goes up to 66C (151F), the system shuts down, & you're focusing on TMPIN2 as the problem? AMD rates the max operating temp for the FX-series at 61C. And I'm curious about the room temp. The CPU lowest temp is 14C (57F) so your room must be pretty darn cold. Either that or the temp readings are inaccurate. That's why it was suggested you try other monitoring software (or check the BIOS) to make sure HWM is providing good info.

http://www.cpu-world.com/CPUs/Bulld...

My guess is the CPU is overheating. More than likely you installed the HSF incorrectly. It's either not attached securely or you applied the thermal paste incorrectly (or both).

I don't know what else to tell you. My opinion is that the NB temp is NOT the problem. And your lack of any feedback is getting frustrating. Please anwser the following:

Do you know the max safe temp for the AMD 990FX chipset? I'lll answer this one for you - it's either 95C or 115C, depending on how the temp reading is taken. See page 5-2 of the following AMD tech doc:

http://support.amd.com/us/ChipsetMo...

In your screenshots, the lowest CPU temp is 14C (57F). Since the CPU temp can not possibly be lower than the room temp, how cold is your computer room? Do you have your tower in a refrigerator? Assuming the room is at least 20C (68F), how can you trust any of the temp readings you're getting from HWMonitor?

Did you try any other monitoring software or check the CPU temp reading in the BIOS?

Let's assume the temps readings are correct & you actually have a very cold computer room. The max CPU temp in your screenshot is 66C (151F). Since AMD rates the max temp as 61C (142F), how can you not see that as a (or the) possible problem?

You said the heatsink is secure & "thermal paste is on there". Was it applied correctly? A single dab in the center of the CPU like seen in the following pic is how it should have been done, any other method is wrong.

The problem was/is that if you tried many of the suggestions, you did not always tell us that you did and the results of these trys. Then there were questions for information that was specific and your answers were sometimes there, sometimes not, and when you answered questions, they were not always direct or complete. The purpose of the questions and the answers are to narrow down the possibilities from dozens or possibly hundreds to just a few. With those answers, we can get a more complete picture of what is/was going on at the time. Since we are not there, we need to rely on you to be our hands, eyes, and ears, not just read the suggestions, but give us all of the feedback (or nearly all) as if we were there ourselves. What you got was a (deserved) backlash of the frustration many of the people felt that were trying to help you. I am very sure that there were many who read the first few answers and decided not to bother at all.
If you solved the issue, thank those who helped or tried to help.
If it was not actually solved, you should not have chosen a best answer yet and tried cooperating more and taking offense less. If you need more help, try less confrontation and more information. If you cannot be our eyes for us, you may need to get local help, probably paying for service.
