I'll give you five debugging methods, try them:
1. There is Trojan horse or virus interference in the computer. Download "360 Security Guard" and "360 Powerful Antivirus Dual Engine Edition". Suggest "scan all viruses and Trojans" to fix computer vulnerabilities!
2. The "player" or "chat software" or "IE browser" you downloaded is unstable, or the version is too old! It is recommended to uninstall, download a new one, or upgrade to the "latest version".
3. It means that you have installed two or more similar software (such as two players, two qq, or multiple browsers, multiple antivirus software, etc.). )! They are not "compatible" together. Get rid of the "extra" one!
4. You can find "Powerfully uninstall the software on the computer" in the "Start" menu in the lower left corner of the computer, and find the extra uninstall! After uninstalling, do a "strong cleaning" (after uninstalling, don't uninstall useful).
5。 If it really doesn't work, "restore the system" or "reinstall the system"!
If this is an accident, it is likely that the software needs to be upgraded or the system is poisoned!
