Hello guys, I got my y580 about 6 months ago it had win8 on it but whenever i play games artifacts would show up so i googled the prooblem and found out if i get bios ver 40 it would fix it so i installed win 7 but found out i still have v89 so i tried the method on this site but i always get an error and the keyboard freezes and have to take out the battery the error is :

IHISI: Flash write error in SMI!

SMI Return Code :0x25

if some 1 can help me i would be grateful thnx in advance !!
