When your computer is not working, the reason could be a hardware or software malfunction. When troubleshooting the computer, eliminating the possibility that you have a hardware problem should be the top priority, after all, if the device is working properly, you can fairly assume that it’s the software controlling the device that’s acting up.
Basically, in PC lingo, hardware is anything physical in your computer. If you can touch it, it’s hardware. Software controls the hardware. Specifically, a program called a driver also called a device driver, is used to control every bit of hardware in the PC. If the hardware itself functions fine, the real problem lies in the driver. Either the driver needs updating, or other software in the computer is conflicting with the device driver.
Computer Hardware Problem
If the computer shuts itself off half an hour after you start using it, no matter which programs you run, that’s a hardware problem. Culprit could be the PC getting too hot.
The good thing is that all hardware is replaceable.
Computer Software Problem
Personal Computer software does everything in a computer. And so it is more devious than a hardware problem. Tracking a problem can be hard as all software has unknown bugs in it and no software developer fully tests programs in all possible configurations.
Solution
The rule of thumb in telling a computer hardware or software problem are these two simple questions really:
1. Have you installed any new hardware recently?
2. Have you installed any new software recently?
If your answer is yes to question number 1, then you may have a defective hardware or the hardware has not been placed/installed properly. Replace or fix it accordingly.
If you answer yes in question number 2, uninstall the software, check if the software version is compatible with your OS (Windows XP or Windows Vista, etc..) or scan for viruses/spywares to see that the software is not corrupted by a virus or malware..
