Menory: G.Skill DDR800 (1+2G) X2 =6 G 4-4-4-12
Harddisk : WD 3200YS
Vedio Card: LeadTeck PX8800GT
I can not stand 8800GT's 100% fan noice , so I order AC S1 (Rev2) heatsink to replace old one, replcace is good, the noice is down, and also control the temp to 43 degree,
then the story comes: I find VISTA Home P 64 SP1 Can Sleep , but when I try to wake up , the PC , CPU(Fan), Hardisk , VedioCard fan start working , but the LCD have no signal, and Wireless Keybord and mouse does not work .
I reinstall chip (MB)drivers
and vedio card drivers ... ... still same problem.
I change DELL 2407 to Philips 190P stll no siginal...
I change BIOS From S3 to S1 , yes, it can wake up, but I need S3 !!!
I check the Device Manger, and find SYSTEM DEVICES -> PCI Bus Properties general say working properly, BUT resources menory range conflicts
