I'm getting some really weird errors with Pcsx2, need it fixed for Youtube content.

Alright, so I'm new here as you can see, the only reason I really made this account is so I could post this topic.

The error I'm getting is seriously bad slow down when the game launches,

Here are my computer specs:

AMD Athlon II X4 processor, @ 3.10GHz per core.
Sapphire HD 7950 Graphics card, @ 860 MHz GPU clock-speed & 2GB Video memory.
8GB ram DDR3, @ 1600MHz.
SSD Windows installation disk @ 60GB.
HDD Program disk @ 500GB
HDD File disk @ 1TB
Windows 7 home Premium 64-Bit

Games I've tried running -
Hero's of Might and Magic - Quest for the dragon bone staff(PAL copy).
there's slowdown during battle sequences and menus.
Videos and map game play seem unaffected.
