I’ll end this with a checklist, a number of things that you can easily check/do if you ever encounter any computer problems. You’ll find the list below can solve many computer problems.
- “First of all, ask yourself what changes you have made to the computer recently (changed settings, adding or deleting programs, and so on.
- Second, ask others who use the computer if they did anything to it recently.
- Make sure the inside of the computer isn’t full of dust or the fan / filter isn’t blocked.
- Make sure all connectors to and from the computer are on solid – even if you’re already sure.
- Make sure no computer cables run under foot, and that you’re not stepping or pulling on them without knowing.
- Check BIOS settings.
- Try starting with the “last known good registry”
- Check the Windows task manager. This will tell you if there are memory problems (or too little memory) and what the processor usage is – if you see 40% to 100% processor usage at idle, you might check what program is running in the background. You can also use the Windows task manager to shut down programs that could be the problem.
- Check the Windows start folders. A program that Windows loads at start may be the problem. Try taking out programs that may be the problem.
- Make sure your computer isn’t too close to another computer or a video monitor.
- Make sure the computer isn’t close to any strong electrical or radio frequency sources.
- Try moving the computer to another location.
- Make sure your monitor isn’t too close to another computer.
- Check the internal power source. Varying voltages can cause weird and intermittent problems. Like overheating, voltage changes can cause the computer to simply freeze. [Warning, the power cage in your computer and monitor has enough voltage to kill you, have an experienced tech check this. Many computers list the voltages on screen at boot, you can check these].
- Make sure internal connectors haven’t come loose, many need to be “snapped” closed. Make sure that all internal components and boards haven’t come loose. [Again, safety first, completely disconnect your computer, unplug it, for a few minutes before opening it. Then still avoid reaching into the power cage/section. Residual charge can last for quite a time if the safety ground gets disconnected].
