Monitor sometimes doesn't turn on.

hey

Basically I'v had this problem for a long time now and Iv finally had enough of it!

OK so... I shut my computer down before I go work or sleep, monitor on stand-by, still switched on at mains. When I go to switch my computer on the monitor stays on stand-by/no signal detected.

The only way I get it to work it by switching everything off at the mains and leaving it for 20-30 seconds. Its although my motherboard isn't detecting my card or something along those lines.

Please don't just tell me to just switch it off like I have been doing, I suffer from back problems and makes it a hard task for me.

Anyone have any solutions to fix this?

Thanks

You need to first determine if the problem is with your computer/graphics solution, or your monitor. So the first thing you need to do is try another monitor on your computer and see if it behaves the same way, and/or put your monitor on a second computer and see if the problem moves to the second computer.

Of course, with back problems, swapping monitors around will be no fun. Hopefully they are not heavy CRT monitors. But this is necessary before spending money on something that does not need replacing - also not fun.

 

I note the OP said,

And of course, turning it off does not fix the problem. And if you turn the monitor off, you cannot (as easily) tell if the computer is asleep. It may still be running, consuming 100W or so, and pumping heat into the room, for nothing.

I have 7 computers in the house, and I let them all go to sleep rather than mess with (cheap, breakable) power buttons all the time. The whole point of such standby states is so we can press a key, or wiggle the mouse to wake the system up. And I note for the vast majority of users, it works perfectly the vast majority of times. Typically if something does not go to sleep, it is because something (besides Windows and your anti-malware solution) is still running.

I am a Spider Solitaire addict. If I leave with the congratulations, you won screen up (with fireworks and sound effects) my monitors will go to sleep, but not my computer. So I have to exit Spider, or leave mid-game. Just one of those things. If I leave Pandora streaming music, my system will not go to sleep.

It IS frustrating when sleep problems have been a frustration for so long, and over so many versions of Windows (and Linux has it share of problems too). With 1000s of different graphics solutions and monitors from 100s of different makers, at dozens of different resolutions, it is a wonder it all does work so well together.

 

hey thanks for interest, luckily for me I swapped monitors with my brother recently to use my ps3 on it, same problem keeps happening. I'm pretty sure its not the monitor.

However, about 1 month ago I cleaned my computer out from all the dust and crap, disconnected the graphics card (fan faces down and couldn't get at it) cleaned it, put it back and had no problems until now. (I had same problem before cleaning) So basically the cleaning seemed to fix it for a month.

I am going to work now so I won't be able to keep updated for 5-6 hours, hope to be hearing from you soon, thanks so far guys!

Well, that suggests it could be a heat issue - though I have never seen heat affect sleep settings like this.

Note I recommend inspecting case interiors for heat-trapping dust build-up and proper fan operation - then cleaning as necessary. That problem with that is the risk of knocking cables and such loose. So you need to make sure that is fine.

Tell us more about your hardware. Is it (and Windows) fully updated? Have you checked for more current graphics drivers? What do you have starting with Windows?

 

SpeedFan http://majorgeeks.com/SpeedFan_d337.htmlis a program that could tell you the temperatures of different components in your sydstem and so help determine if it is a heat problem
