The popular CIH virus in the past few years has destroyed countless mainboards. have you ever wondered whether NVIDIA display chips are under such threats.

The threat is nvflash-a general-purpose refresh tool for the BIOS of all NVIDIA display cards. Many newspapers have mentioned that this tool can only be run in DOS, But I have verified that version 4.42 can be successfully saved and updated in various versions of Windows. This brings us great convenience and saves us the trouble of creating a boot disk, but it also brings us potential threats.

In the help section, we can see that the E parameter of nvflash can clear the content of the eeprom (which can be erased by read-only memory. Because version 4.42 can also access the video card BIOS in Windows, you can also directly clear the video card BIOS content. By default, nvflash can generate a prompt, but it is in the mute mode after the S parameter is used. In this way, if the combined parameters E, S, and 2 are used, the BIOS of the video card is cleared before the system responds. However, do not restart your computer. Use nvflash to fl the correct video card BIOS file. But if you don't know at all, when you restart the computer, you can only be stuck in the dark screen. What's worse, if the parameter Y is added, the system will immediately restart after the erasure is complete and there is no room for saving.

If you accidentally execute a disguised nvflash with parameters, it will become a real n-Card Killer. It is prompted that you can run nvflash-C in the system's "command prompt" to check whether the gpu eeprom is within the range it supports. If yes, you should be careful. It doesn't matter if you are lucky. Just find a PCI graphics card to guide the computer and refresh the BIOS of the bad graphics card. The detailed steps will not be repeated.
