Windows 7: 10 mins running, then it turns off

This sort of a problem is very difficult to resolve by an individual and best left to a professional with a service setup.

The problem appears to be heat-related. Some component somewhere is getting heated up and changes character resulting in a large current being drawn. The over-current protection then shuts off your system. Once that component cools down you will be able to run your system again till the heat shuts it down again.

The problem arises because each and every removable module that makes up your system has to be replaced one at a time till the problem module is found. 1.The Power Supply 2. the Memory modules 3.the Processor (This you have already done and cleared) 4.the optical drive 5.the hard drive and if all these are cleared the mother-board finally.

Once I faced a similar problem. I had only a spare power supply, tried it and cleared it. I couldn't do anything more since I didn't have spares for the other components. So I took it to the ASUS service center, sat with them and watched as they carried out the process. A professional set up like this will have all proven test modules. Finally it turned out to be the motherboard. The diagnosis: the graphics chip in the motherboard was heating up and shutting down the system. The motherboard under warranty was replaced.

Now you know why a professional setup is required for troubleshooting this type of problems.

Hi again Wagner. By all indications, your problem could very well
be related to a temperature issue with the CPU. Lets check this
out first. To do this, boot up your machine, start tapping on the DEL key.
This will get you into the BIOS setup screens. On the very first
screen, on top left side you will see "MS Intelligent Tweeker"
as the first choice. Choose that option and go to the next screen.
One of the items displayed on this screen is "CPU Temperature".
Take note of this temperature. With the machine just idling,
the temp should be below 50C for sure. If it is, leave the machine running at
this stage, watch the temp for changes, and see if the machine
will continue running for an extended period of time.
If it continues running, then we can perhaps rule out a problem
with CPU temperatures. Maybe. Record the CPU temp's. and get back to
us. We can then continue with further diagnostics.
Regards

Wow! in about 15 seconds it reached 95C, then it shuted down...I'm wondering if I burned the whole system turning it on so many times..
It lasted on 20 seconds, a lot less than usual.

Ok, we have pretty much eliminated Windows 7 causing the problem. If your CPU
went that high right away, then the CPU is definately overheating. Now, as to why. You say that you replaced the CPU chip.
1. Who replaced it. You or a service tech.

2. If you, did you replace the Thermal Paste between the CPU Chip and the Heat Sink?

3. Is the Heat Sink securely attached to the CPU/Motherboard?

Let us know the answers to these first few questions.

Well...I replaced it, it didn't seem that hard.
I put the chip in the mother, secured it with a metal tablet, and then I put over it that metalic circular thing with the fan on it (sory for not being precise with the terms!), it had some screws, not very conventional I have to say, but I think I attached them well.

Hmm the paste? Shouldn't have Intel send it to me with the whole thing? I mean, if I ask for a replace of the chip, it is quite obvious I'll need the paste.

Ok. This leads me to believe that either there is no/proper Thermal Paste between the CPU Chip and the Heat Sink OR the Heatsink/Fan Assembly is not mounted correctly/tightly to the CPU. If Intel sent you a new CPU, did they also send you a new Heatsink/Fan assemble? If they did, the new Heatsink usually has the Thermal Paste already applied to the bottom of the Heatsink.
If it is not a Thermal Paste issue, then the heatsink assy. might not be seated proberly/securely on the CPU.

I would review your manual regarding CPU replacement proceedures, beginning on page 13. Pay particular attention to the statment "Once the CPU is properly inserted, use one hand to hold the socket lever and use the other to lightly replace the load plate. When replacing the load plate, make sure the front end of the load plate is under the shoulder screw.

They also gave me the Heatsink, so we can asume the paste is included. I'll check how to mount the whole thing now.

You mentioned in a previous post that used screws when replacing the Heatsink/Fan Assy. ????

There should be no screws involved on your setup. The Heatsink Assy. has 4 posts, one on each side. The points on these posts should line up with 4 matching holes in your Motherboard. Once you have the assembly on the CPU and the 4 legs through the holes in the Motherboard, you must now seat them. You do this by firmly pushing down on 2 opposite sides postes until you hear them click and lock into place. Then do the same to the 2 remaining posts. If they are properly locked on, you should not be able to lift the assy. off the Motherboard by lifting it up.

John, thanks for trusting yourself and think "this guy is probably an idiot...he might have had problems installing the heatsink" and you were right! haha, I forgot tu push the screws down so it was quite loosy (I thought it should be that way, but well...not) the CPU temperature goes from 32 to 35 C now, which I think is a terrible good new
I don't want to claim victory yet, it might shut down again and I might come back crying for help, but for now everything's working just fine.
Seriously, thanks a lot to everyone!!

Just a heads up. You might run into issues later down the road due to the amount of times you overheated your CPU.
