Or you could start it before going to bed, and let it run all night. Once you’ve prepared the boot media, shut down your PC.

To restore the processor to its default configuration, reset the complementary metal-oxide semiconductor, a component that stores hardware settings. If you continue to receive the error after following all the steps above, this is a sign of a more serious issue.

If any of the issues or messages above are encountered, you likely need to replace the CMOS battery. The process to replace it is detailed in the following sections.

• While powering off a device, CMOS traces out a number that should match with another one generated by BIOS while booting.
• Regardless of what you do, it is almost impossible for that to affect data ntdll.dll download stored on the hard drive.

Overclocking increases the operating speed of the central processing unit to boost performance, while underclocking decreases the operating speed to reduce power consumption. Overclocking can cause the workstation to overheat and put the internal hardware at risk, while underclocking can hinder productivity. Sometimes changing the speed too much can render the computer unstable.

At this point, we would recommend taking your computer to a computer repair shop to have them diagnose the issue. Unfortunately, most manufacturers do not list the exact type and model of the CMOS battery. Once you have located the battery, we recommend you write down its specifications (voltage, chemistry, wiring). If possible, remove the battery and take it to a retail location. With some computers, you may need to disconnect cables, remove drives, or remove other parts of the computer to get full access to the CMOS battery.
