No-one I know is even on Twitter. Except two people I met a gazillion centuries ago and never stayed in touch with. Journalists.
Journalists make a life out of periodically saying something even if it is nothing.
If I would have twittered my day yesterday it would have gone like this:
... (nothing) (because my computer didn't start up)
... (still nothing) (it only emitted a series of beeps)
... (long beeps) (six) ...
Didn't start up at all. The fans came on, but there it stopped, dead - just six very long beeps then nothing at all. Helpless.
OK to be honest I then did go online with my other computer and searched the forums for "computer won't start, beeps". There I found that it was A: without a doubt a hardware problem B: beeps are Bios code C: could be the CPU / motherboard / fans / memory / lots of words I don't know and can't remember D: how to take out the CMOS battery (which did not help)
One of the posters asking about the same problem told the forum visitors that he was asking them before giving up and forking over his money to the "geek squad". I expected one of the replies to say "we are the geek squad" but no, they simply told him, the answer. Sort of. I can't really remember if the answer was there, all the stuff I read seemed hopelessly more complicated than what I had to do to fix it.
After opening the case I took the memory banks out of their slots one by one, starting with the old ones, and that did it. It has two 1GB banks (new) and two 512B banks (old). One of the 512MB banks is defective. If I leave it out the computer starts up. It now has 2.5 GB of memory installed, which is funny because I thought memory banks always need to be installed in pairs, and if I take one 512MB bank out it would not see the other one any more. But it still does.
