I am assuming you have chosen power supply powerfull enough to  handle all the power consuming hardware instaled in the PC. Please try unplug all connectors from the motherboard and plug them back again. Sometimes this solves the problem.

Gateway monitor 2100 won't turn screen on, blue lite is on as if monitor is. but screen is not on. can it be fuse or what ? is not v-card


It sounds like the lamp for your monitor is no longer receiving power. While you can attempt to fix this issue yourself I wouldn't recommend doing so as it doesn't mean it will work after you attempt it.
If the monitor is under warranty still then you should contact the manufacturer about a RMA. If the monitor isn't under warranty then you should purchase a new monitor.

Lcd-17v8 monitor power won't stay on. westinghouse monitor


If the monitor turns on and goes directly to sleep, or it powers on briefly and shows an image then goes black then the monitor is defective. The first is often an I/O panel issue inside of the monitor. The second is typically a lamp failure within the monitor.
A simple test would be to plug a different monitor into your computer or this monitor into another computer. If the monitor doesn't work on another computer or a different monitor works on the same computer then the monitor is the issue.
If the different monitor does not work on the same computer or this monitor does work on a different computer then something on the computer is to be suspected such as a driver issue or a faulty video card.
If you find the monitor is defective then you should dispose of it (assuming it is not under warranty) at a nearby recycling center and purchase a new monitor. I would suggest something by Acer, Samsung, Dell, HP, NEC, or Viewsonic. These brands cost a bit more, but have much better track records.

This is usually down to the cable and fuse rather than the device. You will need to buy the right power cables/power adaptor to have the device work in that country

Sounds like a problem in the speakers' internal power supply, maybe a faulty capacitor. Speakers need to be looked at by a technician, or replaced with a new set.

Tv has been turning off right after you turn it on then after a few attempts it would stay on now the power button on front turns green, it tries to come on but then turns off.


Sounds like high voltage power supply has gone bad. You can try purchasing new PS online and replacing yourself if handy or you will need to bring in for service.

I HAVE A Z-2300 NO SOUND


Is it plugged in with a 3.5 millimeter jack? If it is, pull it out of the computer and press you thumb on the tip, if no humming noise comes out, your speakers are probably blown.

However, if a humming noise does come out. Please check to make sure the volume on the computer is turned up/unmuted, the software's volume is turned up/unmuted, your sound card driver is installed (Right-Click "My Computer" -> left click on properties -> Click on the Hardware tab -> click on "Device Manager" -> Click the "+" next to "Sound, video and game controllers" and make sure there is no Red "X"'s or yellow "!"'s.

If you do get a hum, and you do have everything set up right in Windows, try a different pair of speakers or head phones. Your sound card might be fried.

Also, make sure you're plugging the speakers into the correct port on the computer (It's usually a washed out green port"

Dell tower desktop Dimension 5100. Tower makes whistling sound.


sounds like it could be a bearing in your hard drive. is this problem constant? If so, I would open up the tower and disconnect the hard drive and then power up the tower again. if the sound goes away--you need to get a new hard drive. If not, you could have some dust bunnies in your cooling fan.

This is an Irish Machine and all i get is a slow green blinking light, no noise, no movement so I wondered if it was because of the power supply


The mains voltage is different. If the desktop has a switch mode power supply that has a mains voltage selector switch, then switch it to 110 volts and it will work, but if it doesn't then you need to purchase a switch mode power supply and install it in your computer, make sure it matches the total wattage or higher than the old power supply.
The monitor usually don't have a switchable voltage, you most likely need to buy a new monitor or use an existing one.
