Monitor Not "Waking Up"

[The Voice]

Hey all!

I recently bought a new graphics card (nothing fancy, cause my system is quite dated - AMD HD 6670 2GB). Everything's been running great, until about a week ago: my monitor (Samsung 226BW) does not come out of standby when moving the mouse or hitting any key on the keyboard. It will briefly display the desktop image, then goes off again, the power light flickering blue (as it does when it's in standby). After a minute or so of wriggling the mouse around and mashing keys, switching the power on and off on the monitor, it'll come right. In extreme cases (first thing in the morning usually) I've had to hard boot the PC. Everthing is normal after that, until the monitor has to "sleep" again.

I've scoured the interwebs for a solution, and tried every "fix" possible, but the problem persists. Everything from changing the DVI cable, reseating everything on the mobo, to rolling back drivers, then updating them again. Of course, a lot of sites outright said it's down to HW failure, and a few said the 226BW specifically has a habit of dying (sucks, cause I really can't afford a new one now).

Any ideas/anyone with a similar experience and a solution?

System Specs:

Intel E6750
Gigabyte P35-DS3L Mobo
4GB Kingston DDR800
Gigabyte AMD Radeon HD 6670 2GB (New!)
Can't Remember The Brand 600W PSU (New!)

Does this only happen with your new graphics card?

Try putting your old graphics card back in, and running it for a few days, and see what happens. If the problem still crops up, I'd blame the monitor. If not, then its something else. If you don't have your old graphics card, then try swapping monitors with a friend/colleague/relative/work PC, and see what happens.

BTW - what input ports does the monitor have (DVI, VGA, HDMI?) and what output ports does both your new and old graphics cards have?

Go into your BIOS and enable the option to "RePOST video on S3 resume" (or it will be something similar) and see if that solves the problem

I had the same when I bought a Philips 29" monitor. I changed the power settings on the NVidia control panel and it works fine now.

What power settings did you change? I have 2 x Phillips 23" monitors connected to a Dell XPS 15z laptop. Every now and then one of the monitors will show "no signal" and Windows won't detect it. I have to then either remove and re-insert the display cable or power-cycle the monitor. Very rarely, I will have to restart my PC in order to get Windows 7 to pick it up. The laptop has an Intel HD Graphics 3000 and NVidia Geforce GPU. I have not come across power settings in the Nvida Control Panel, which is why I am asking...

Win 7 64-bit

Update: disabled power down mode. Set a screensaver. It wakes as intended when the mouse or keyboard are used. When it's switched off, the sleep mode problem is replicated. Will play around with the BIOS when I get home

P.S: the old and new carda used DVI (both had VGA ports though, too)
