it's not a stupid thing to do (i do it all the time, maybe because i'm a big cheating bxxxxxd

)
first off you'll need to figure out which is the right save,
if you look here
http://www.sonyindex.com/Pages/PS2_US_Serial.htm (<-for future reference)
(and search using googles find Ctrl +f(within that page), you'll eventually come across the serial number of your game )
http://www.sonyindex.com/Pages/SLUS-21621.htm
( it appears your games serial is SLUS-21621 )
now you'll need to do a search for SLUS-21621 on your harddrives
if you have windows xp it could take a long long time
if and i say if you played it on the latest stable build
http://pcsx2.net/244-pcsx2-1-0-released.html and not one of the many svn builds available, you will be able to just copy and paste the .p2s file into the stable build listed above,
if not you'll have to find the svn build you used last to play your game on by searching for SLUS-21621 (it will have a few numbers and possibly letters in brackets after the serial) and will be in a file called sstates
saddly sometimes (not all the time) you won't be able to take your savestates and put them in the latest svn builds
anyways if you did use an svn build and it was corrupted you might be able to find it here
http://pcsx2.net/download/development/svn.html
if you can't see it there, pm me and i'll have a look to see if i have it,
remember ! don't ask me about bioses as it's against the rules, i can only reupload the actual emulator, any requests for my bios will result in you being ignored (sorry i had to get that out of the way)
as for recovering savestates (if your drive suffered a massive crash and won't boot) their are many types of recovery software out there (i'm not sure what the best type is or if i could mention any here) but because save states are reasonably sized (14-20 mb) you should be able to salvage them (personally i back my states up in loads of places such as memory cards etch)
if they are corrupted and you can't salvage them, you might be able to request one or two from another member here
i hope you can understand all that waffle
Not sure what graphics card you have, it's memory bandwidth,
it's temperature, fan speed, what pixel shader it has
try TechPowerUp's
gpu-z
Not sure what your cpu is try
