Question about Computers & Internet
Hi, Are the Power Management settings correct? In the Control Panel, open up the Power Options. In there, make sure that the Turn off Monitor is set to Never, and that the Power Scheme is set to Home/Office Desk. Apply and OK. Here are some places to start. Is the computer itself still running (can you hear hard drive fans etc?) if so then here are your possibilities Please accept the solution if it's helpful. Do get back to us for any further query. Thanks for contacting fixya.com
1. Check the monitor cable. Make sure there aren't any bent pins.
2. Reseat the graphics card, if it's not integrated with the motherboard (removes and reinstall it -- making sure it's seated properly).
3. Right-click on the desktop and select "Properties". Click the "Screen Saver" tab. Click the "Power" button. What settings are in there?
Bad signal/power cord on monitor. Move the cables around to see if the screen comes back on if no then see next.
Your monitor itself could be going bad or overheating, however this is the least likely of any of the options, so its one to get back to.
Video card over heating/going bad. Do you have a built in thermostat? if so what's the temperature reading when you loose signal? another option is to buy a computer thermometer or sticking one inside the case. Also try removing the side panel from the case and see if it takes longer for it to loose signal(better air flow, so lower temperature, if that works then you need to get additional cooling in your system). And as posted above reseat the video card/check connections. Also ensure that all fans are in fact operating.
CPU could be overheating. If this is the case the whole system will shut down, to see how to trouble shoot/fix this again see above post.
Now this is the mostly likely issue if your computer is running after the monitor goes black.
PSU has gone bad. The reason this generally identifies the PSU going bad is that the systems are built that if voltage drops, the computer automatically turns off the one thing it doesn't need to keep running which is your graphics card. Even if the power goes back to the correct output, it will not turn the graphics card back on without a reboot. In this case if you have another PSU you can test inside the case that is the only way to tell for sure wither or not the PSU is bad. Multimeter tests can be done, but they are not a guarantee because it may not be fluctuating at that exact moment your doing the test. though it is a test that should be done.
So If you here noise after monitor turns off first check:cables, then reseat card(s), then(or during the other tests) check temperature. as all those test cost nothing but a little time to do. then swap/replace PSU.
If the PC isnt running:Check temperature, this is almost for sure your issue. PSU should also be checked though.
For temperature if temps are above 48 degrees C you need to get additional cooling in the PC with fans, though this may only help some because if the case design is bad you will still not get proper air flow. Another option would be to with the side panel of have a fan or two blowing inside of the case to help cool.

Follow these steps o find out and fix the problem :
1. unplug your monitor from the CPU ( tower ) and then plug the monitor to the power supply and turn on, if you get the color bars on the screen that means the monitor is fine. But if you don't get it that will indicate that the monitor is faulty.
If you donot get the colour lines try unplugging the cable and replugging it.
I don't think it is a virus because if you have a virus your computer will not fail at POST ( power on self test) it will at least initiate the boot process.
If you don't see anything at all that means a hardware failure on you try to boot your computer.
