Monitor goes to sleep and won't respond.

geno368 · Aug 6, 2011, 10:38 PM

I have a 1 year old Gateway desktop running Windows 7 home premium with 4gb ram. Sometimes, when I am working and the system may be idle for 15 min or so, the monitor will go into sleep mode. It shows no signal, and no keyboard action will awaken it. I have the power settings to never turn off and the screen saver is off as well. I swapped out the monitor with another and it did the same thing, so I think I have eliminated hardware. I then went to the device mgr and attempted a driver update, which said I had the latest driver. The only way it will come back on is to cold boot the system. BTW, I have reseated the video cable as well. I have looked at the m/b and all looks ok. No bulging capacitors or excessive dust on processor, etc. Keep in mind, that when this monitor goes to sleep, the system is still operating correctly with fans running and the power light is on steady. No matter what I do to try to wake up the monitor, is is not responsive. I have to hold down the power button on the tower for a few seconds to shut it down. I then wait a few minutes and bring the system back on.Also, when this happens, the keyboard is dead as well.
Thanks

Check your BIOS for any form of sleep or power saving settings as they can conflict with or over ride Windows settings.

Thanks for the reply...I could not find any power settings other than non selectable in bios...BTW, I also changed the video cable as well. Since it doesn't have a video card, should the chipset drivers be updated? Is that the driver that controls the video?

This happens to me occasionally. I have found that if I overclock my FSB and in turn the PCIe express bus that it will not resume from sleep. Have you got any overclocking anywhere?

Sometime it will do this even if the PCIe is set at stock 100. In these instances I put the system back to sleep and wake it up again. My POWER button is set in Windows 7 to put the PC into sleep.

What video card are you using?

I don't have a video card..it is just the stock pci and I don't have a clue about overclocking...it is just a stock Win 7 prem
