Lenovo all in one IdeaCentre B320 showed a virus in Chinese after I downloaded a photo editing software then screen became white..I can hear windows starting but white screen remains..it starts with black screen for 2 seconds, then stays on white screen thereafter..could it be a 'white screen' virus? Has anyone been hearing of such? Recently bought the PC and didn't use it much..Need solution please. Thanks.
Never heard of a white screen virus. It could be a virus, it could be blocking something. Or it could have just been two things not related happening at the same time. Try connecting an external monitor, when the computer is off, and then turn it on. If the display itself is the problem, it will show fine on the external monitor. Should you see the same problem on the external one as well, then it still may be hardware and not a virus, but there are more things to try.
If it does show the same problem on the external monitor, shut down again and remove it. Then start up the computer in "Safe Mode" and see if it will load fully. If it does, then it may well be caused by a virus or malware. You would have to then remove the problem. If, however, it won't start that way either, then you may want to consider taking it to a tech (or contact the manufacturer if under warranty) as it can get complicated from here to see if it is a more serious problem.
How to enter "Safe Mode" when booting the computer.
In Windows 8 and 10...
As your computer restarts, press F8 (possibly a few times) to enter "Safe Mode"
a. Press the "F4" key to Enable "Safe Mode".
(The computer will then start in "Safe Mode" with a minimal set of drivers and services.)
b. Press the "F5" key to Enable "Safe Mode" with Networking.
( Once "Safe Mode" with Networking starts, Windows is in Safe Mode, with additional network and services for accessing the Internet and other computers on your network.)
c. Press the "F6" key to Enable "Safe Mode" with Command Prompt.
(In "Safe Mode" with "Command Prompt" starts Windows in Safe Mode, with a Command Prompt window instead of the Windows interface. This option is mostly only used by IT professionals.)
Now sign in to the computer with your account name and password. (If you have one set.) When you are finished troubleshooting, you can exit "Safe Mode" restarting your computer.
In Windows 7/Vista/XP...
1. Immediately after turning on the computer, or restarting it (usually after you hear your computer beep), tap the F8 key, repeatedly, in 1 second intervals.
2. The computer will then display hardware information and run a memory test.
3. Next the "Advanced Boot Options" menu will appear.
4. In the "Advanced Boot Options" menu use the arrow keys to select "Safe Mode" or "Safe Mode with Networking" and press ENTER.
