I am having a problem on the desktop PC. My monitor screen is black off while the CPU is still running.
I had run the monitor on another CPU where it worked fine. I had try to uninstall the graphic card Sapphire X550, shut down & switch off the PC and then remove the graphic card from the expansion plot.
After re-plugging the graphic card and switching on the PC, I installed the graphic card driver again. Now, the desktop is working as normal.
I had try to set the MHz to the lowest MHz at the right click desktop properties. After a few day, the same problem come again.
How to find which part of the system is creating issue - graphic card or the motherboard?
Thanks in advance for the help!
System Configuration: Windows XP Internet Explorer 6.0
i had the same prblum and it tooks me 2weeks to find out what is wrong with my pc
it is simple the cable which connect you monitor is the problum ,your pc doesn't give signal to your monitor or your monitor connector a pin is bended or missing you grafic card is not reading don't be confused
is very simple
power saving off mode it means (no segnal from your mother board to your monitor )
I had the same problem and found a solution - or found out what was actually the problem.
First of all let me say that it is not the CPU or the harddrive!
I tried un-pluggng all the cables and re-plugging it all back in again - but nothing worked.
Then I pressed the on-button on the monitor and held down the Auto button which is also located at the bottom of the monitor screen.
I had a menu option that said 'repair windows environment' 'advanced option' 're-start windows' etc.
I chose to 're-start windows' - this restarted the computer but I still ended up with a black screen.
So I repeated the above process of pressing Auto and on-button, menu came up. I selected option 'repair windows environment'
Then after loading and 2 screens that flashed - I got a black screen with white writing, a little down the screen it said something like 'repair windows environment' and then a count down timer in seconds. This option is a waste of time as there is nothing wrong with Windows. I selected the next option down 'start as normal' and pressed enter.
My screen was back!!
I closed it down and re-started it to see if it worked. Black screen again!
So then I started to adjust the cable head - the part that is plugged into the monitor.
First time it did not work but I did see some light flashing so I continued adjusting then pressing the on button on the monitor and suddenly it came on, I could see my desktop icons.
I am having this problem a lot now and have to always adjust the cable head - so I think it must be the cable.
This happened to me. I opened up the computer and took a look at the video card (zotac geforce 7300), it is slightly over a year old. It looks like new except the capacitors are all blasted out the tops. Like this article talks about http://en.wikipedia.org/wiki/Capacitor_plague
I think this is a thermal issue with this monitor. I am now on the second monitor from dell and both have had the issue where it starts shutting off after 30 or so seconds. The power button remains green but the screen is black. I have rigged a 60mm fan, approx 4CFM, to the rear louvers of the monitor to blow inward. This keeps my monitor going. If I turn the fan off it shuts off in about a min. From what I have noticed there is probably some issue with the thermal cutout switch or the thermal management design all together.
Just keep turning the monitor off and on until it stays on. Eventually it will. It took me about a half hour of turning it off and on before it finally stayed on. Then don't ever turn it off again, it might not come on again. I got the tip from an online forum - it works!
