At times, PC parts such as our video cards, sound cards and network cards can have a bearing if they are not properly plugged in. Especially if your computer is not the traditional packaged computer set which we normally get from vendors like IBM or Dell, chances are there will be errors or overlooked placements when we assemble or buy cloned PCs.
To some, it may be a matter of checking out the loose peripherals but at times, they do have a bearing as far as blue screens and PC crashes are concerned. There is no definitive explanation but perhaps one aspect that contribute to it is the conductive nature. If the slots are not properly fitted towards the cards we install, chances are the processors and the software we use will malfunction due to erroneous reading or even because of lose threads that need to be properly installed to function properly.
It may sound mediocre in nature but they do have a part. When you notice your PC hanging or suddenly showing you the blue screen, you are limited only to the software or hardware issue. Most of the time it points to the software for most as pirated or bugged software can really be a pain in the neck. But after successive installations and you still get the same errors, open your CPU and start checking those pins and slots. The problem may be because of some loose connection that you have failed to consider in the first place.
