Windows Screen Saver wont work and i cant find the cause

hi all.

i have just freshly formateed and re-installed Windows 7 on my pc inorder to find whymy sleep and screen saver/timeouts are not working.

i havve tried to trouble shoot it, and come up with nothing. it is currently a bare bones system, with windows, MoBo Drivers and latest windows updates. that it. and it still wont work.

command prompt gives this

Code:

C:\Windows\system32>powercfg -devicequery wake_armed
HID-compliant mouse
Intel(R) 82579LM Gigabit Network Connection
Realtek PCIe GBE Family Controller
HID Keyboard Device

and this

Code:

C:\Windows\system32>powercfg -requests
DISPLAY:
None.

SYSTEM:
None.

AWAYMODE:
None.

it is currently installing some updates, but that shouldnt effect the screen saver comming on.

any other sugestions on what i can try to find out what is stopping it from working?
