There's something weird going on with computer generated sounds on my PC.
I have no idea where this might come from, I suspected it might have something to do with my sound card or with the MIDI on it, but there's something that makes me think it's not that.
Basically, whenever I keep my computer on for too long ("too long" can mean "more than 4 hours" or "1.5 days", but never in the few hours after I (re)start it), and I'm using MIDI software, like software for composing (
Sibelius,
Finale,
Guitar Pro, etc),
the rhythm is screwed up. Badly. I mean sometimes it just gives the whole thing a "swingy" feel, but if I don't restart my computer, it will get as bad as to have whole notes shorter than 4ths (which should be, obviously, 4 times shorter)! It seems like the computer is "jumping" ahead, never staying
too long on one note but staying
too short on all or most notes (and not equally on each, which screws things up terribly).
Interesting enough, that coincides with a similar aspect - when this happens with MIDI software, something similar also happens in games. All games that... how could I describe it? All games that have a "character" that the player plays as.... all those games speed up. A lot.. Like, I'm playing GTA San Andreas and the cars go so fast around me that I can't even cross a street without being hit 4-5 times. It just seems to be normal and at some point, just like in MIDI, "jump ahead" faster than normal. And it doesn't happen in one game, it happens in them all. It happens in Fifa 07, it used to happen in Spiderman 3, etc!
Restarting the computer fixes this. And it doesn't affect recorded/non-generated sounds. For example, I can watch a movie and it will never "jump ahead", or go out of sync.
What could be causing this?
