Your computer seems to be malfunctioning — it’s slow, programs are crashing or Windows may be blue-screening. Is your computer’s hardware failing, or does it have a software problem?
Hardware problems and software problems can lead to the same symptoms — for example, frequent blue screens of death may be caused by either software or hardware problems.
Your computer or laptop slows down over time due to software installations and programs loading as the computer starts, or it has been infected with malware. The conclusion is that computer is slowing down because it’s old, so you replace it. Wrong!
If a computer is slowing down, it has a software problem that can be fixed. Hardware problems shouldn’t cause your computer to slow down. There are some rare exceptions to this — perhaps your CPU is overheating and it’s down-clocking itself, running slower to stay cooler — but most slowness is caused by software issues.
