Losing Signal to Monitor - Help!!

I just finished my second build and am having trouble with the signal from the vc to the monitor. All I do is use it with a cycling trainer software. Sometimes (no pattern), during the workout, the monitor will go blank and the screen will say "lost DVMI signal". The computer is still on, receiving input from the trainer and after moving the mouse the screen comes back to life. I also tried a different monitor and it didn't make any difference. Not sure how to begin troubleshooting.

Any suggestions?

Here are my specs

AMD Phenom II X4 925
ASUS Black 24X DVD+R 8X
ASUS M4A785TD-M EVO AM3 AMD 785G HDMI Micro ATX AMD Motherboard
CORSAIR CMPSU-650TX 650W
G.SKILL Ripjaws Series 4GB
GIGABYTE GV-R567OC-1GI Rev2.0 Radeon HD 5670
Western Digital Caviar Black WD1001FALS 1TB
Windows 7 64bit
 
The loss of signal message is a bit perplexing. Other than that, it almost sounds as if the monitor power saver is actuating. Not all software is seen as "user input" by the OS, even though the trainer may be doing things. If I start a slideshow with a graphic app, after a while the monitor shuts off. Try extending your monitor shutoff time in "Power Options" and see what happens.
 
Nanobyte, it appears that your suggestion has worked. I'm still curious why the monitor is not being "seen". when I look at the driver for this monitor in Win 7, it shows a generic driver and not the ASUS driver. It also states the driver is up to date. Could this have anything to do with it?
 
If that fix worked, great. It's nothing to do with the drivers. There seem to be certain things that initiate screensaver and (monitor) power saver. They should not come into play if there is manual input every so often. If that does not happen, the OS seems to assume nobody is interested in what is going on. I don't know if this occurs when playing movies because I'm frequently pausing for breaks!

To give an example, if you are rendering complex video, the process may take 12 hours. Well, you're not interested in watching that (it's a close competitor to watching paint dry) so there's no reason the OS should not turn off the monitor to save power.
