Monitor Entering Sleep Mode Randomly

Okay, this started a few days ago. I came in after working out and bumped the mouse once as I passed by, to get it out of sleep mode (the Monitor). Well, there was no pop or click (which occurs when the monitor comes out of sleep mode), so I tried again. And again. Nothing was working. I had to reboot the computer, and it worked fine after that.

Following this, the problem occurred several more times. It either occurs across the night when the computer is idle for a while, or while I am watching a movie file on the computer (for example, I am watching House MD. It'll do it once every episode or two, requiring a reboot). I've disabled the powering-down feature on the monitor settings but it still does it, irregardless of activity.

I've spoken to Enceph about this and he initially was inclined toward my video card being the problem. But he changed his mind once I mentioned that my monitor is about 5-6 years old. I've been thinking this might be its way of saying "I'm out, chief." But I don't want to blow a healthy amount of cash on a monitor if that isn't the problem. Any other recommendations, or do you guys think it's the monitor as well?

If this were the video card, I'd get the Blue Screen of Death or something of the sort. But these movies hardly put a strain on my system. I play Rainbow Six: Vegas quite often on it as of late and that doesn't cause lock-ups or anything of the sort.

Jam it back in, in the dark.

Does unplugging and replugging the monitor to the VGA card get it out of standby mode? Because that's what happens when you restart the machine.

I also think it's the video card. Monitors often destruct themself if there is any major problem. Or they loose signal (collapsing image) and never come back.

There's nowhere I can't reach.

If you wish to diagnose the monitor's health, try plugging it into another computer and see if the problem occurs. Confirm your results by plugging another monitor into your computer, as well.

Tried unplugging and replugging in the monitor with no response. I'm leaning towards it being a MoBo or (possibly) Power Supply issues.

I doubt it's either of those. Right now, it seems like a monitor problem. If you can, plug it into another computer to test.

I was speaking idiomatically.

If it was a monitor problem, I wouldn't be able to bring it back on, restart or not. The problem would progressively worsen, but it's been kind of steady as of late. I lack another computer to plug this into, unfortunately.

What kind of toxic man-thing is happening now?

I've had a similar situation to this occur in the past.
My parents computer had a monitor with built in powered USB ports. When the monitor would go into sleep, or standby, with the USB ports would cause some sort of disconnect. Once I disconnected the main USB line from the PC to the monitor the problem went away. You could listen for a usb disconnect chime when the monitor goes to standby/sleep mode.

Good luck.

/ There are a few different types of sleep mode that computers use, and sometimes you can pick what type to use in the BIOS.

How ya doing, buddy?

Ahahahah ='D It's the MoBo. Woke up today (Xmas mornin') and started up my desktop. And... What's this? There wasn't a beep for startup. My curiosity was piqued. So, down I went to look at the back of the tower beneath my desk. The green lights on the back of the USB part of the Mother Board were now Orange. Oh, happy days =D EVEN MY COMPUTER IS IN THE HOLIDAY SPIRIT.

It was all "sorry bud! It was me. I was just joshin' ya!" So, problem solved. Desktop won't start up due to a sour MoBo. RMA will be with me by tomorrow, I'll mail it the same day... And get a new MoBo.

What, you don't want my bikini-clad body?

hy sorry i'm late, was googling the topic as to why it was happening because funnily enough it's happening to me too :\

not sure why though... my cousin said it was to do with cooling but i haven't had the time to get a new fan in... let alone enough money to get one.
any tips?

Jam it back in, in the dark.

Well, it was an indicator that my MoBo was dying. And the final symptom was that one morning it wouldn't boot up.

There's nowhere I can't reach.

:\ hmmm... thanks, that's a bit.... crap, my comp is only about a year old...

thanks mate

This thing is sticky, and I don't like it. I don't appreciate it.

My mobo was only a year old when it fried =( Still, I'd do some more probing before going out and buying one off NewEgg.
