Memory Issues Cause Over 80% of Random Freezing and Blue Screen Problems
Random Blue Screens Often Point to RAM Problems
If blue screens occur once or twice a week or randomly during the day, memory errors are the most likely cause.
RAM is accessed randomly during use. If the faulty section of RAM is used on that day, a blue screen will occur. If only healthy sections are used, the PC may appear to work fine for that session.
This can happen regardless of whether you have one or multiple RAM sticks.
Even if you have an 8GB memory stick, a faulty sector can cause freezing or blue screens whenever the system tries to access that area.
