之前的系统没有这个问题，就是win10有这个问题，过一段时间就会出现这个问题，网上找了很多，最后发现是显卡驱动的问题，是A卡的问题，只需要更新A卡驱动即可，如果更新A卡驱动不行的话，或者说A卡驱动已经是最新了，那么就去设备管理器回滚驱动程序到上一个版本。
更新显卡驱动的方法：
桌面上右键，Radeon设置，然后
如果更新驱动不行那么就回滚驱动：
win+X，然后打开设备管理器，然后双击
然后回滚驱动
不行的话可以卸载干净这个驱动然后重新安装试试。
我开始是卸载驱动然后重新安装，这个方法还是不行，然后我回滚驱动也还是不行，最后是更新了A卡驱动解决的。当然不同人的情况不同，方法都可以试试，感觉好像A卡有更新就会出现这个界面。
下面是国外找的一个帖子：
I reinstalled the graphics Drivers (amd), on a hunch (the fuzzy text), wich seems to have solved the problem. for now at least. :-) I believe the trouble startet when i removed a dysfunktional AntiVir Program. why this Problem turned up is beyond me. I can't see the connection. but I don't believe in coincidences.
Edit: 01.May.2016 [download the Specified Driver Install Routines BEFORE fiddling with the System]
1. use amd clean uninstall utility (run as Admin)
2. use for example ccleaner or the like to remove ALL remnants (Registry) Including All Autostart references to ANY Amd startups And delete the AMD Folder "c:AMD" (in which the Amd Setup Routine extracts)
3. you may have to repeat Step 1 and/or 2. (the amd cleanup Utility sometimes misses stuff).
4. the Crimson Edition 16.4.2 Hotfix (non whql) IS NOT a sure way of getting rid of the Problem ON ALL Systems. Use the Crimson Edition 16.3.2 (which apparently uses the AMD Radeon Software Crimson Edition Display Driver version 16.15.2211)
On Win 10: using the "automaticaly search for updated driver" option from Device Manager, may revert the Driver to (the faulty) whql, which in Turn may bring you back to square one.
to summarize: Clean Install, Running as Administrator, after removing everything as Administrator, Including the AMD driver extraction Folder.
