Why won't my computer screen turn on?

Why does my computer screen stay blank when I turn the computer on?

  • After running XP Pro on my desktop computer with no problems for 2-3 years, my computer abruptly froze and slightly garbled the screen. When I rebooted, the computer would hang during the boot-up process (the only way to turn it off was to unplug the power cord) - however, the screen stays blank the entire time. I have tried a new monitor, video card, power supply, CPU, CPU fan, and RAM with no change in symptoms. I even tried resetting the motherboard and built a barebones system, but that didn't fix the problem either. I just replaced the motherboard, and the computer is now booting up and turning off properly with the power button - but the screen is still blank all the time. Oh and there are no beeping sounds whatsoever when I try to turn the computer on. I've basically built a brand new computer (with the exception of my optical, floppy, and hard drives). Does anyone have any suggestions on how to get rid of the blank screen?

  • Answer:

    Once you installed the new hardware, especially the motherboard you would have to do a reinstall of windows, but if you have done all this I am sure that you are aware of that. If the new motherboard won't even display POST or prompt for cmos I would be interested to know what the problem is. Are you using onboard video on the new MB? Not to belittle you, but are you sure the new monitor is powered up? (check the obvious. Is it connected correctlly? I would start with the barebone that has the new MB, use onboard video, and a known good monitor and see if that helps. If you can get something change things once at a time and document the results so you don't repeat things. Good luck!

If you have to Video cards as in one built in and one you added to the system as> aftermarket. You might need to plug the monitor into the other built in card. Seems your missing the driver file or the driver file has been corupted. Som anitvirus or PC- cleaners will remove unwanted or list as unwanted unused driver files. When your booting up from BIOS trying holding down the F8 key for safemode and go to option Last known working configuration. If not the take your Flash drive or USB flash drive to another computer and download the lastest driver file for your VGA cards then run them as a SATA drive from the beginning of your windows ntuser boot. I hope this works for you I've had the same problems. Yours Truely, C-INET 1DAWG

Try doing a fresh install of your operating system and go back to Yahoo answers after that.
