I got this question from a reader in my queue this morning. So here is a quick response:
Top 3 reasons for computer freezing with lines on your computer display
Please, note, there may be other various reasons, but most common are:
- Graphic card is dead
- CPU overheating
- Software conflicts
So how do you know which one is the most likely to be the one behind this issue?
- If it permanently crashed with the lines, it could most likely be be reason 1 – graphic card is damaged, corrupt or dead, and needs to be replaced.
- If it only happens occasionally, it could be one of the other two reasons – if your CPU is overheating, it can cause all kinds of havoc, including this one. Software conflicts also could cause an occasional problem – especially if you are a gamer or designer and have many graphics-dependent services running on your computer.
Start your computer in safe mode (refer to your OS maker documentation on how to start computer in the safe mode for your version of OS)
Check if the issue still in effect in safe mode. If you don’t have this issue in safe mode, most likely it is a third party software program or service conflict.
To determine which one could be the menace, restart your computer and boot your desktop normally. Once done, perform a clean boot (a process that starts your computer only using bare minimum in terms of drivers and startup programs). Doing so helps eliminate software conflicts. Again, refer to your OS maker documentation on how to clean boot for your version of OS.
If neither actions pinpoint the issue, then overheating is the next one most likely one.
