I'm having trouble with my emulators. Considering that Genesis, SNES and NES games are the only things I play on my PC these days, I haven't noticed this problem with anything else other than explorer. I'm running a fairly powerful PC on Windows XP with plenty of RAM and tonnes of disk space. I leave my computer on for the majority of the day, and after a couple of hours, everything slows down to a halt. It's especially annoying when I try to load up one of my emulators, because all of my games run very, very slowly, and they're quite unplayable. I can play them with no trouble for about two hours, but after this time period, everything seems to go to pot, as they say.
I've tried increasing my virtual memory, I have enough RAM and HD space, and I don't have any sort of viruses, so I don't see what the problem is. Basically, if someone can help me make my emulators work at full speed, even when my computer's been on for hours, I would be grateful.
The problem isn't with the emulators themselves, either, because it's happening to all of my programs.
Can anyone suggest anything?
