I have a Gateway 310 XL H desk top PC. After the storm, Isaac, It won't power on. The red and green lights come on, the red goes off after a short time. The monitor flashes a manfacture logo then


The system is powered up if green light on, the hard disk is powered up if red-light on for a few seconds then goes off, but I assume it's not loading up after that. You have no output to video.

Try holding f2 or f4 to load default bios when turning on. If that doesnt work then That would point to me that there is a problem with either:

1) processor burnt out, or needs refitting following a knock to the case causing a bad connection.

2) ram burnt out or not correctly installed. Try refitting the ram or using a different combination of ram.

3. Bios chip burnt out. Sometimes you can literally see the chip is slightly melted.

4. Other motherboard fault, look for melted chip or damaged component.

5. Psu faulty or not connected properly. Check connections, or bench test with another psu.

Have you moved the pc recently? Sometimes dust builds up under processor or along ram, and when moving pc giving it a slight knock can cause bad connection. If dusty, remove clean and re install.

Hope it helps.

ok your monitor is a separate issue and start by checking the blue signal lead from the back of the monitor because for some reason the monitor isn't getting any images to show

HP Pavilion is powered on. Monitor is flashing green, red, blue and white.


Hi,

The monitor is performing self-test check and proves to be in good condition. Check vga(blue)/dvi(white) cable connections that connects your monitor and your desktop.

I hope this works for you. Goodluck! if problem persists, kindly reply for further assistance.

I have a dell Dimension 2300 and the images are very dark. I don't think it is from the monitor.


Try these steps: 1. Check the monitor settings. Access the On Screen Display (OSD) Menu System. Adjust the contrast and brightness using the control buttons in the monitor.
2. Run the monitor self test. Unplug the video cable from the computer (cable from monitor to the back of the computer). Usually it has a blue or white connector. Turn on the monitor alone. It should display the self test pattern (white, red, green & blue). If the images are dark in the self test, it is a problem with the monitor.
2. Rotate the monitor to face a different direction. This will help in eliminating sunlight glare which can cause poor picture quality.
3. Test your computer using another working monitor. If the problem occurs in a known good monitor, then it is a video card or motherboard (if your video card is integrated) problem.
I hope these options help.

Dell flat screen goes white and colored block appears and floats


Check that your monitor is connected properly and tightly to the computer. If it is, then the monitor may be bad. Borrow a friend's monitor and try to see if it works, if someone else's monitor works, then replace your monitor.

Computer powers up, but monitor shows a self test


Your video output is bad. Either the video card, or the onboard video built into the computer. You need to swap out the card or add a card to bypass the built in video port on your computer.

Computer not booting up


Could be one of two things:

1. Signal cable from monitor isn't hooked up. (either monitor end or computer case end)

2. Video card in the computer is damaged and not putting out signal. This is unlikely though as usually this will trip the motherboard into beeping when you turn the computer is turned on.
