Vista - S3 STR Sleep Can NOT Wake up

driver me crazy:
my PC details :
MB : GIGA X38-DQ6 BIOS F9a
Menory: G.Skill DDR800 (1+2G) X2 =6 G 4-4-4-12
CPU: E6550
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
pls. see the picsorry it is Chinese ) :


Powercfg /a says system support S3:




I am sorry my OS is Chinese, but I can NOT find answer from China, pls. help, if you guys need transfer into English, just let me know!

Why Pci Bus memory range out ? driver problem?

I think so yes...You can use that same device window to change the conflicting memory address

Keep us updated.

Dear Steven：
I try all actions list by Power Options and Sleep Mode Problems.
Remove wireless keyboard and mouse does NOT wake up,
change Power Plan Option does not wake up,
Check the atartup progrom does not work,
even system restore, still same status.
... ....
the only thing does not change is PCI Bus still memoryrange out,
I suspect this is the root cause, But I can not fix it.
Next step I will do :
1. Change vedio card,
2. use a new harddisk to install VISTA again, to check PCI bus problem.

I Find it !!! Fianally !!! the root cause is 175.16
really,I use Nvidia chip like 4 years , and ATI 3 years, I was always think Nvidia's drivers is much better than ATI, until now! looks like he make a jok for me!
I make a mistake , that is update drivers to 175.16, and sametime change the heatsink, this remind me , Never do more than one case in the same time.
I try to double corform the driver problem ,
1. uninstall 169.25 , and clean up all Nvidia's drivers , and just install forceware 175.16
STR can not wake up.
2. Do not uninstall 175.16, and install 169.25, s3 still can wake up.
... ... I am sure it is 175.16's Problem!!!


P.S PCI Bus memory range out still there,still look on them! Does anyone using 64Bit and Memory >=4G post a screenshot of PCI Bus for me ! I start believe it is not big issue.
