Vista - can't get vista to sleep recently

I have this problem not long ago.
I tried to turn off the monitor in 1 minute and sleep in 2 minutes, I tried
on 3 different power plan. Only the monitor goes black after 1 minute but my
pc still awake.
I closed all the sidebar, bit defender V10, not good.
I have a Hauppage PVR150 MCE TV Card installed.

In command prompt my windows version is 6.0.6000.
I type powercfg -a and I can see: The following sleeps are available on this
system: Standby < S3> Hibernate Hybrid Sleep
The following sleeps are not available on this system: Standby <S1> <2>
The system does not suppport this standby state.

Anyone can help?

Have you installed any hardware, or updated any drivers lately? Perhaps you
could try a system restore point. Also, you might want to test your memory
to make sure it isn't the fault. Windows Vista has a memory testing program.

Try the memory diagnostics tool. Type "memory" in the start search box to
find it. It will require a restart.

past two weeks. It goes to sleep and then just hangs there. Nothing
on the display but the machine is still running and needs a hard
shutdown.
