Many things can bring the PC out of sleep mode.
Wake up on Lan (Correct in Bios)
AV software off to do a check, not good to switch that off.
TV Guide update?

Possibilities to check:

If the PC is normally completely shutdown
- Wake on LAN/modemring/PCI. e.g. maybe your TV card is inadvertedly sending a PCI 2.2 "wake" pulse to the mainboard
- PSU. If it is old or there might be fluctuations in the mains to unsettle it.
- Timed wake up, in the BIOS.
- Cordless keyboard if it has a dedicated button to signal wakeup or power to the PC.

If it is normally in a sleep/standby mode then in addition to all the above, check
- Sunlight on mouse. Can confuse the sensors into thinking that there is movement.
- Sunlight on IR remote sensor on PC. The smoked strip should filter this, but maybe it's not completely covering it.
- Windows indexing service or similar "scheduled" services like defrag, GoogleSearchm etc.

Even if you don't want to use Wake on LAN, it is worth checking any utils that came with the NIC. Many cards can be set to wake on any activity that reaches them, not just wakeup packets.

- Does the gigabyte have a wakeon lan function? icant find it in the BIOS
-The PSU is the 1 that came with my antec case
- Cant find anything in the BIOS settings
- Cordless keyboard is the keysonic one and that doesnt have any wake up switch
- The antivirus doesnt have a schdeuled scan
- The defrag was set as a schdeule but iv disabled that
- iv got a wireless usb reciever

Do you know what times this happens? If so, have a look in Event View in the System and Application event logs and see what is kicking off at the same time.

hi iv checked the event log. theres nothing in there. iv got vista also. im just going to try it running a network cable to it instead of the wireless reciever because it never used to do it. also i noticed a windows update that keeps failing to install could be that??

anyone know where the wake on lan function is on the gigabyte board?

The compro card can wake the machine itself if you re-route the power-on button via the card. Have you used this option?

I use the MCE standby tool. My PC still wakes up occasionally but then shuts down. Normally 7.30am. It must be to do with TV guide updates etc. You sure if you left it it would shut down itself after 5 mins?

THanks sorted now.
Unplugged the power cables from the tv card and now its ok. Do i need the power cables plugged to the compro tv card or can it be left plugged into the slot to view tv

Hi,

Glad you sorted it, not sure what card you have, but I'm using the Compro S350 DVB-S card and I don't have power cables plugged into it i.e. it's just in the PCI slot with a satellite feed going into it.

HTH,
Tony
