Hi,

I have just finished upgrading my HTPC for FreeviewHD capability & some weird things are ocurring. If I press the sleep button on my MCE remote to power down, then resume, I have no video signal from any port or the TV output -no POST screen or access to BIOS. I am forced to replace my card with my older 6600LE version, boot up, then replace my Asus card.

Other things that occur when this happens:

-the CPU & system fan will start up, then shut off after about 1 second
-I have no network signal on my ethernet switch for this PC

I have tried it & it happens with both video cards. I am about to reinsert the Asus card.

What could cause this?
I read on another forum that a person was told when his ATI card system had a similar video signal issue to up the PCI-E voltage in BIOS.

The hardware is: -all with as-bought BIOSes

Gigabyte GA-M56S-S3 mobo -never overclocked with standard voltage etc. settings
AMD AM2 4800+ CPU
Asus EN8500GT Silent Magic video card-512mb (no extra 5v connector)
Silverstone 400w PSU
Silverstone Lascala LS14 case
3x SATA HDDs (all on prior system)
Hauppauge HVR-220 DVB-T tuner card
Hauppuage 150MCE tuner card

I Ghosted the last OS image from my previous setup which I do not believe should have caused any issues?? How about potential conflicts with HAL??

I am planning to reinstall my OS but need to get to the bottom of this prior just in case it reccurs.

Also, is it normal for the8500 series cards to not show POST & bootup images on TV output? This was never an issue with my 6600LE card & it is a damned nuisance as my primary screen is a 4:3 CRT TV. Thanks.

Well that’s the first thing to do. Check if there is a later bios for the motherboard. Unlikely to be later bios's for anything else but that is a definite first step.

Done. Updated BIOS to latest version: no difference, except, maybe, I can now resume from hibernate. Don't think I could before, as all my tests were from standby.

I tried swapping in another PSU: same issue. It will resume from hibernate but not standby. I need standby as I can't remotely switch on the HTPC. Looks like I will need to contact seller & try another mobo.

I have just bought one of the new Intel DP35DP Media Centre mobos. Cost me $140 and will wake up on LAN activity from either Standby or Hibernate.

This has proved to be a mixed blessing, in that I cannot leave Skype running or else the PC restarts itself within seconds of powering off.

However, by quitting Skype before Standy/Hibernate, my PC will stay in whatever state I left it.

To restart it remotely, just attempt connection via VNC. It will fire up but meantime the first connection attempt will fail. Wait a few more seconds and try again; it will work every time. Good old XP with 25 second bootup time really rocks for situations like this

It was a faulty motherboard or processor. The motherboard was replaced but after the hardware reinstall, I got no video, again.

I swapped out my Sempron CPU from my client machine & everything works: will resume from standby with no issues. I tried the 4800+ in the client & no video from my DVI (client has a Samsung LCD display).

To the tech-heads: could the CPU have been the issue all along? I'm not conversant enough with the inner workings of CPUs to know. Thanks.
