The volatile memory has to clear, which is why turning it off and then back on fixes a lot of problems. In some cases that doesn't happen unless the computer is off for longer than a few seconds or may even require actually being unplugged. I heard a hypothesis a while back regarding static electricity or something keeping the memory active and motherboards with slight imperfections regarding how the power supply is wired , but never followed up on that.
Also, there are little gremlins that live in our computers and like to mess with us. Regular sacrifices of liberal arts majors keeps them happy.
This liberal arts major just buys her computer presents. A new wireless mouse. A wireless track pad. A special stand with extra USB ports. A remote to control DVDs. Skype so it can make friends with other computers. Pretty soon, an upgrade on the OS.
Along with regular dusting of the screen, gentle pats and lots of compliments. Bestest little computer in the whole wide world.
Hey, it works for me.
I even bought my laptop another laptop as a "friend" (don't tell it that it really a "spare" - since I'm on the spare right now, the first laptop doesn't know about it). I hope.
Actually, not even a spare - I bought a used laptop that came in with a failing graphics card just before vacation. I was able to track down that the particular make & model had an extended warranty period - and that I had run a diagnostic test on the laptop on the company's website - before the end of the warranty period - documenting that it was failing before the warranty expired....three days before I tracked down that it existed.
They fixed it under the extended warranty - praise (fill in the blank here).
But I had already ordered a second laptop of the same make & model so that I wouldn't have to go on a trip without a working laptop (VorGuy doesn't share laptops and I had a LOT of stuff I wanted to do - update ereader, play Solitaire, check email, check local tv listings, print off tickets to tourist attractions that had been bought on-line, track the repair of Laptop #1, and the delayed delivery of Laptop #2, which came in after we crossed the Texas border on I-10 heading east...
I did get it working for trip #2 and came back to find Laptop #1 was here & repaired (new motherboard & new graphics chip).
Between Ubokia, Craigslist, and the Oodle Marketplace on Facebook - you'd think I could find a buyer for the Spare......but, no.
And I'd rather have a spare than sell it (with a larger hard drive & more RAM) for less than I paid for it in the first place. Besided - it's a two story house and having a working computer upstairs & down saves my knees from having to climb up or down the stairs to go to a different floor to get to the computer.
And I know I'll have a working laptop for my once a year major project next week....it was no fun to have to go BUY and set up a new computer three (four?) years ago when my laptop DIED in the middle of the first day of a four day project. Which took an extra two days due to the need to get a new computer, set up a new computer with the software, run several tests of the installation of the software, and then try to work faster to "catch up". I no longer try to work faster to catch up because the hurrieder I go the behinder I get. It takes longer to clean up the mess made by going too fast than it does to take my time and do it properly the first time, every time.
