PC wakes alone from sleep mode and nvidia drivers crash

[MagusxD]

Hi guys, i have a small problem with my pc which drives me crazy, im using windows 7 x64 ultimate the problems im experiencing is this : PC goes into sleep mode, only to wake randomly some time later, then it goes againt into sleep mode and wakes up again , second problem when i wake it sometimes the nvidia drivers will crash, or not, but if i try to play any games, the pc will hung during some minutes into the game.
I dont believe this is hardware related, settings on bios are at default, latest bios is flashed, windows updates all done tried several nvidia drivers and used ddu uninstaller to clean before reinstallation, run memtest overnight, run prime95 for 12hours, run msi kombustor to stress test the card around 6-8hours ... what else should i do ?
My system consist of this
psu: seasonic 650g
cpu: athlon 860k
ram: kingston 8gb
mobo: asus a88xm-a
gpu: gtx750

Any advice will be really helpful, thank you

The zip you uploaded does not contain any crash dump.

Follow it: http://www.sevenforums.com/tutorials/174459-dump-files-configure-windows-create-bsod.html
Go to Option Two, Point 2. Download the .reg file and merge it in registry by double clicking it.

Now wait for another BSOD. When it occurred, search the .dmp files manually in the default path: C:\Windows\Minidump or %SystemRoot%\Minidump. See if the crash dump is recorded or not (hopefully it will be recorded).Post it following the Blue Screen of Death (BSOD) Posting Instructions.

Dont run any disc cleanup tool before you upload another zip.
