Maplestory Bosses Glitching Out

Hmmmm seems like your graphics card texture buffer is malfunctioning, most likely due to overheating or overclocking.

Things you can try:
- Update your graphics card driver
- Completely re-install maple
- Clean your videocard cooler with a brush
- Replace the cooling compound between your videocard (core + mem) and the cooler
- Underclock your videocard core + mem (opposite of overclocking, try 25% lower speeds)
- Overvolt your videocard a little (+10% is safe)
- Check powercables in your pc from the PSU towards your graphics card (if there are any)
- Clean your current PSU inside your PC (pull the plug first plz )
- Try another PSU in your pc

Only do most of these ^^^ things, if you're know what you're doing!

Now tell me where these things are and how to do what you just said. I suck at computers.
