what and where is driver version do you install? from MVIDIA or ASUS support site?

http://rog.asus.com/forum/showthread.php?10885-G74sx-rising-temperature-Please-help gives you all the information you need.

1) If you have cleaned the fans on your G74SX and still get the high temperatures you report just by Browsing, you'll need to get a repaste to bring the temps down to normal levels.

2) If you didn't upgrade your Atheros WiFi driver from version 9.0.0.222 to 9.2.1.432 or later, you'll have high DPC Latency that will result in TDR errors you report, where Windows resets the GPU when it detects a 2 second delay. However, the high temperatures of your processors may be contributing to the problem.

You have to address your overheating issue.

Edit: Make sure to read dstrakele thread he posted and about the Wifi issue, I also didn't know you already made a thread about this and you already got help there too.

I have encountered that error before on my old system. I might do a thread about this actually because this error is the biggest pain. Prepare for a long response.

Yes that nvlldmkm.sys error... it is a huge problem. The issue you are having is an TDR problem. There is actually a little fixed that Windows have provided. Firstly I would go to BIOS and set to default settings and clear CMOS before you go to these steps. See if clearing CMOS and defualt settings has actually make an improvement while on Windows for 10 minutes or so.

More info of TDR:

TDR fix:

Now this isn't a fixed but it will hopefully stop that hung error from the hardware that is causing that bug or error. Firstly I would unintall NVIDIA drivers by using Driver Sweeper and install this NVIDIA drivers:

Your GPU and CPU is kind of hot on idle especially on the small CPU usage. I'd did have an issue before with an GPU on idle at 30 C and when doing gaming or opening up 3d applications it jumps to 60-90C in just a few seconds... which wasn't normal. I might be guessing that your system is causing that error.

Your other problem might be running applications or hidden applications that is causing or using your CPU and GPU to heat up on idle. Firstly I would open your laptop and make sure to clean dusts off etc and make sure to add new thermal paste on CPU. If you haven't noticed any amount of change on temperature, it is something defiantly wrong with the system to heat up strangely on windows.

It also wouldn't hurt to go to BIOS and look at the temperature from there and see how your system is doing on BIOS. Now there is allot things you can do while your in Windows to check what applications is running on start-up. First of all go to start, run and type "msconfig".

- System configuration should pop up
- Click on Startup tab
- Make sure to un-checked every single of them.

Now Apply OK. This is the first bit of checking start-up programs, we also need to know the hidden start-up as well. OK while you got that done, restart your PC. If you see any changes of temperature or anything let me know - If it's still the same then we go to this step.

Its an anti-hack application that is checking what is running on your start-up. WARNING: This program is for experts if you delete or remove anything that requires a windows to start it will cause you to reboot Windows. So I wouldn't recommend this part to you but if you need help which ones to remove send a report to: http://esupport.trendmicro.com/en-us/default.aspxo tell you which files are suspicious, I can help also just send a PM to me if you like.

Here it is:

Now when you get the file downloaded and installed, run it as administrator.
Click on "Do a system scan and save a logfile" - the logfile you can send it to me.
After they scanned it they will show a big list of applications that are running.

More Info about those files:

This where you checked things and remove, that's it. Remember be careful if you are not familiar with this or skip this step. So far so good, I have found these great applications as well, I just find these last 3 months and they've helped me allot.

Its a helpful tool to tell which files are corrupted or errors.

These are also very helpful if you encounter BSOD:

They are both helpful and give accurate information. This will tell you your crash dumped files and what BSOD error. Now there is also this application to know if your system is stable, while running applications, games and so on:

http://www.resplendence.com/latencymon

Latencymon is a very helpful tool I thank Nodens for that tool. It really helps and show's which system file is the main root of the problem. You just get it download and installed then run the program and go to the "Drivers tab" and click on "Highest execution" to see which file is giving you high results and you will find out that the high results is related to your BSOD errors.

Now what was my nvldmkm.dll error was you are saying? my northbridge was dying. nvldmkm.dll can mean any part of hardware is malfunctioning, its not mainly on GPU. I'm guessing that your system might be malfunctioning causing those instability issues and temperature issues but lets hope not and hopefully its an software issue or your PC needs cleaning up.

This is my thread about the nvldmkm.dll error and I thank everyone who have supported me.

If you don't want to go through this process, you always can reboot Windows (no internet) which will defiantly help to solve if it isn't software issue. If your system is still overheating and giving you that error its more likely to be an hardware issue.

Hope I helped.

Glad you replied, you can post the both logs here, I'm sure some of us can tell you which files are suspicious. I also have done that little trick with the cmd before it also worked for the first time but it happened again. To clear CMOS you must disconnect the laptop from power, then remove the actual battery from the motherboard for 10-15 minutes, then place it back. I'm not sure if laptops have jumpers but that's the best way to go.

Now you have mention that your CPU and GPU are in fulload when browsing the net? If so you have to disable "Hardware Acceleration". If you are using a different browser you can type on google "disable hardware acceleration on (your browser). Also try change on your NVIDIA settings "Power management mode" to "adaptive", because when browsing the net your GPU will still go to full-load.

Hope we get this sorted out, my large guess would be an hardware issue as it did to me. Hopefully its an software issue, virus etc and not an hardware issue. Your English is just fine 🙂 we will see you on the weekends. Normally I had an nvlddmkm.sys issue with this new rig I am using but that was my MSI afterburner settings causing it.

Remember nvlddmkm.sys can not only mean its the GPU it also can be any hardware issues or software causing an bug to the hardware.

Its still very strange that your hardware heat up very quickly in just a few seconds by browsing the net and such. Yes like you said make sure to know by steps which files on start-up is causing your system to heat up. I'm almost to 100% that its an hardware issue with one of the hardware's or motherboard. Hope you get the bottom of it.
