It is possible that an OS gets damaged enough over time that it may not boot and run.
But there is BASIC MAINTENANCE that folk seem to never do that can help extend the life of the PC. Installing the OS is sadly not going to correct for dried out heatsink compound, failed fan or clogged heatsinks. Here's a prior discussion about this.
Yes it may die but most of the time I find the owner not able to tell me what canned air is.
I read everywhere that an old computer (HP Pavilion) should be replaced and will eventually die. I also read that you can revive and remove problems if you replace old XP with something newer like Windows 7. And I read that you can revive computer by replacing hard drive/disk.
I am not a techie - can someone provide info on all of the above? Don't want to buy new desk top but have Windows 7 to install if that is the way to go. What started my questions is that (rarely) it will lose connection but also read that could be overheating or simple problems, not too serious and not fatal. Thanks.
