The "experts" here asked you for more information too, like what do you see, hear or smell (anything burning, do you see flames?) when it tries to boot? Are there any flash codes, noises, error messages on the screen, what LED lights power on? What is the exact Make/Model No. of your system. Remember, troubleshooting hardware issues over a BLOG is difficult enough without end users providing the necessary information for proper troubleshooting. Then, no one can assist you.
As far as crash free laptops, well, that's just too idealistic. Human bodies aren't even crash proof, and they were designed by a GOD.
All I"ll say on laptops, is what I have been telling people for years - laptops suck! They are made to be obsolete in 3-5 years to make $ for the companies that make & sell them! Period! Otherwise, they'd last for 10 years and be upgradeable every three years with the fast changing design modifications.
Laptops do not last, the small HDDs are NOT durable, motherboards aren't made very well, you have to backup your data and use power management to save wear & tear on the systems. You have to keep them elevated and cool, avoid bumping and jarring the unit, you really have to baby them. But, people don't listen to me though, they only pay attention when they break down. Then it's too late.
But, with that said, I have like 8 laptops, 4 decent ones, they ALL work for the most part - some work better than others, but only because I am familiar with laptops, how they work, their anomolies, what precautions to take etc. One big precaution I take - I DON'T BUY NEW LAPTOPS! I find broken ones, fix them, then when/if they die, get another used laptop. New laptops are one of the biggest tech ripoffs out there today!
Just another stupid saying...
