Installs when using Gigabyte VGA, probably has something to do with GPU clock
Appeared on a new install of windows 2003 SBServer with a Gigabyte AGP
This is the Nvidia RealTime Clock controller. It scales your processor down for 2d and up for 3d, saving power and heat generation. Comes with Gigabyte cards.

Its a happy thing. Definatly.

I Installed a DVDplayer, PowerDVD, on my laptop which was included with a Gigabyte video card I purchased. The video card was an nVidia 4000 series. I believe the NVRTCLK is used to tweek the video clock on mVidia G-Force boards. I Don't think you need it unless you have an nVidia video chipset. The laptop I installed it on has an Intel video chipset. I don't know if it's needed to run PowerDVD.

I too have a NVIDIA Gigabye VGA so that is probably correct
medium amount
This rtclk error depending on what type sometimes just controls the menu which is called rtclk MFC
It is from sofware of gigabyte video card
Yup, the problem lies in the NVIDIA/Gigabye VGA software. Here is how I solved the problem. First go into add/remove programs and remove anything Nvidia and Gigabyte (vga, not mobo) related; including updates. Then go into system 32 and find the folder “NVRTClk” and delete the folder and its contents. Reboot. Do not reinstall the drivers from the oem Gigabyte CD! Do not mess with the “new hardware wizard; close it. Go to the Nvidia site; downloads and use their drop down list(s) to find your card and download the drivers; they should be as up to date. (I didn’t need any updates) Save, close. Save, close browser and then run the .exe file. Select “custom” install option, check mark all boxes AND especially the one marked “Do clean install”. Once loaded you will be prompted to reboot; reboot. Problem solved; no more error message. Open Recycle bin and delete the folder you deleted from system 32.

Best practices for resolving NVRTClk issues

A clean and tidy computer is the key requirement for avoiding problems with NVRTClk. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the NVRTClk.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
