Question about Dell Dimension 2350 PC Desktop

1 Answer

Monitor Issue When I boot up the computer, the monitor will go through all of the start up procedures, but then there are flickers up and down the screen. Also, the screen will randomly turn off and on every few seconds. It gets worse when the mouse is moved. I tried another monitor and had the same results. Any ideas? Thanks!

My computer starts flickering at boot, then the screen goes black!


It is probably the monitor. Hook the monitor to another computer and test.

My HP A735W is turning on but stays in power save mode and no key board or mouse function


I think the issue is your monitor. If the monitor constantly says Power Save Mode and not let anything else display then the monitor might be bad. See if we can isolate the problem by the steps below.

Try booting up in Safe Mode and see if the monitor works ok.

Turn off the computer, then hit the power button to turn it back on and immediately start hitting the F8 key repeatedly until you see SAFE MODE. Take the Safe Mode option and let it boot up. Safe Mode will look different to you, the screen will be darker and the icons bigger, this is normal. If it works ok in safe mode then the monitor is ok and we might have an issue with a setting.


Try connecting another monitor to your computer. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the computer. If the Borrowed monitor works ok, then your original monitor is bad. If the Borrowed monitor does the same thing as your original monitor then the issue is with the computer (possibly the video card).

Computer wont boot Evo d510


Choose within this options with regards to your monitor: 1. You could replace your monitor with a new one. 2. Or you could send someone or send it to a technician to repair your monitor.
Boot Up Problem: 1. Try checking the Power Supply Unit (PSU) if it give out 12Voltz. If not you could replace it with new PSU. 2. Check the motherboard if there are some blown out Capacitors. If there is, send it to a technician to replace it. If none, replace your Processor. That is the defective. That causes the boot up problem.
On boot up screen. Of course it will not show a boot up screen because there is a problem on your monitor. And so, there is also a problem on your motherboard (Processor or Capacitor).
Hope this might help. Thanks.

Display starts out OK, but after a few minutes it begins to flicker in the upper corners, and the turns on and off a few times before staying black?! Everything else seems to function OK.... BIOS issue???...


please check the monitor or LCD that you have. because the computer will not flicker if there is a problem on the display. isolate it. use other monitor or LCD then check if it flickers again.

Monitor intermittently goes blank, esp. after computer has been running for some time. Turning monitor off and on solves for several minutes before it happens again. Bad video card, or monitor problem?


If another monitor is available, then I'd suggest trying one and see if the issue follows the monitor. OR Try this monitor on another system.

If neither option is available, boot the system in the Safe Mode (F8 at boot) and see if the issue occurs in the safe mode. If it does, then I'd say the monitor is the more likely failure point.

If still under warranty, contact Dell, if not, then generally cheaper to replace a monitor than to pay for repairs.

My screen below the taskbar keeps on flickering


that sounds like a either a monitor issue or video card issue. in most cases, if it is a video card, you wouldn't see the image on the screen. I would try the monitor, if you had it for quite a while, it is possible that the monitor is going bad.

I know it is not software problem.

Remove any disk inserted n your computer (floppy or cd) and try again.
Check the cables connection and monitor connection.
If no boot, try boot your PC using the CD restore provided with your machine

MONITOR ABCs
The monitor is a hardware device which physically connects to your video card. The monitor allows information and current status be be visually outputted similar to a TV.
monitor.gif Like most TVs, the computer monitor has a CRT, or Cathode Ray Tube, which is found inside the computer monitor as illustrated in the above picture. The CRT is the main component and most expensive part within your computer monitor. Within the CRT are three electron guns, Red, Green and Blue. Each of these guns streams a steady flow of electrons, left to right, for each line of your monitor. As the electrons hit the phosphors on the CRT, the phosphor will glow certain intensities. As a new line begins, the guns will then begin at the left and continue right; these guns will repeat this process sometimes thousands of times until the screen has been completely drawn line by line. Once the phosphors on the CRT have been hit with an electron they will only glow for a short period of time; because of this, the CRT must be refreshed, which means the process will be repeated as explained above. If the video card's refresh rate is not set high enough, you may encounter a flicker or a noticeable steady line scrolling from the top to the bottom of your screen. If you are encountering this issue, resolutions have been described on our video card page.

MINIMUM RESOLUTION The size is an important factor of the computer's running resolution. When picking the resolution, try basing it off the monitor's size for best use. 13-inch 640 x 480 15-inch 800 x 600 17-inch 1,024 x 768 21-inch 1,280 x 1,024


Hope this works for ya/Please dont for get to vote.

Is this a Software/Config/Hardware Problem ?


hmmm..sounds like a sleep or screen saver conflict...try booting up on Safe mode(F8) on turn on, and then see how that works. Set your screen saver for Never, and see what happens.

You may be hitting a thermal issue with your video circuitry.
