Home computer, after prolonged use (more than 3 years old) recently started to fail: stopped working first one, then the second rail. Moved swapped SATA cables on the motherboard — it worked.
Now periodically during operation of the computer there is sound critical errors (so nasty, you know) and after it's shutting down half the functions of the computer cease to run programs, browser, if opened, does not open links, quip does not open new Windows, not invoked context menu, first on the desktop, and in a minute — in public folders does not start start. And all these actions are accompanied by sound unacceptable errors, only the error never climbs.
Even noticed in KMPlayer movies shows fine, if it was started before these events, but if you call the context menu — instead of 20 points is 4 and they don't work.
I think it's a glitch of some windows system file. But how do you know what and what to do?
UPD: the same thing started to happen on a netbook
