Hello, my CPU is AMD Athlon64 3000+,MBoard is 939NF4G-SATA2,which Nvida chipset. When I try to use "suspend", the PC can stop work,i.e screen becames black,cpu fan stop running.etc.that seems ok. but when I try to wake it up by pressing keyboard, it didn't wakeup, then I push the "Power" Button and quickly release, the cpu fan is running now, but screen is still black. so, I cann't use my PC. I have to reboot it by pressing the "Power" button more than a few seconds , then it shutdown and I release it and press it again, now it start rebooting. so, how can I let "suspend" works successfully? Thank you all very much! Paul ZHU
