Who hasn't seen the Windows XP blue screen? Quite a few people may encounter it frequently, so how is the XP blue screen actually caused? We can explain the reasons for the occurrence of the blue screen phenomenon from both software and hardware aspects. From a hardware perspective, excessive overclocking is one of the main reasons leading to the blue screen. Overclocking causes excessive internal calculations due to overloaded operations, leading to CPU overheating and resulting in system calculation errors. If you want to overclock but avoid the blue screen, the only solution is to implement proper cooling measures, such as replacing with a powerful fan and adding some heat dissipation materials like silicone gel, which will help a lot. Additionally, moderate overclocking or not overclocking at all is also one of the solutions. Whether to choose stability or higher speed depends on your own decision.
