Statistically speaking failures do indeed have a time period attached to them. 95% of all bad PC parts will fail within the first 3 months of use, A HDD rapidly gaining bad sectors is likely to die in short order, and a video card with bad VRAM either typically dies immediately or exhibits artifacting at an increasing rate. You are right in your use of "may", because while it "may" still happen after the period I've specified it's statistically unlikely given every other case of memory issues I've personally experienced or helped with. You say things like "I can safely say" but then you follow that up with "may". You appear both confident and unsure in the same sentence, which makes sense gives your comments are inexact and non-constructive. Here's a good rule of thumb in regards to picking your arguments on forums: If you believe an argument is incorrect you had better make sure without a preponderance of a doubt that the counter-argument you are making is correct. I'm certainly not saying my logic is inflatable but for you to come and say I'm wrong with such a flimsy counter-argument is frankly wasting everyone's time. You've provided no evidence to back up your opinion, you are off topic, non-constructive, and being rude. Even if I turn out wrong in this case I would not accept advise from someone who feels the need to force their opinions down other's throats.
