Hello, I'm new here, but I have a horrible problem. I ran on my computer old games for over a year, with Dosbox (longer, counting previous computers, but that's not part of the problem).

After a month or so, of not using any game launched by Dosbox, I today tried to play a game on Dosbox, and the game was working very slow. It was a Realms of Arkania 2 Startrail from gog.com, so I just tried to reinstall it. But it gave nothing. Later, I noticed that all Dosbox emulated games slowed down, not only that one. Independant Dosbox, D-Fend, GoG games, all works now slow, but before it worked very good. What could happen? My computer seems fine, as new games, and other programs work fast.
