My Dell destop computer goes to 3 seconds of Dell Computer screen then 3 seconds of press f1 or press f2 screen then goes dark after being turned on. Cannot go to safe mode. Please help me


From what you are saying it would appear that you are not even getting to the Operating System. There are a few reasons this could be happening. Wen you start up, at the F1-F2 screen, select whichever key will take you to the Setup (CMOS) menu. Once there, search the main screen to see if the hard drive is recognized. There should be at least one hard drive in the bios menu - more if you have more than one installed. If there is no drive there, then you may have a hard disk error or failure. Check the cables to the hard drive and the mainboard. If that is fine, then search the menus for boot device and boot priority settings. Ensure you have the the hard drive selected as boot device and that it is first priority. If it is not, change the settings accordingly. If the CMOS and the hard drive seem to be working properly, then most likely you have had some sort of corruption of the Operating System. There isn't much you'll be able to do with that without having an OS or recovery disc.

In my case it turned out to be a weak power supply. It would work sometimes and not others. If stone cold, it would not boot. If I unplugged 1 thing, like the hard drive or the CD Roms, it would boot. Tested the old power suppy and it seemed to pass. But once I connected a new power supply, the computer has worked fine ever since.

Start wont load window, just flahing light on screen. may have got virus


Remove hard drive, find out make and model of hard drive. Go to hard drive manufacturer's website and download testing software (if you have another computer with internet access). Should be a bootable ISO file. Burn the boot cd and run it on the host computer after reinstalling the hard drive. Sounds like a bad hard drive in my opinion.

Computer problem


Hello,

If you are referring the green or amber light on the front of the case, it could either be the power led or the hard drive activity led. If its the hard drive activity light, it usually just blinks when a program accesses the hard drive.

Thanks

Black screen not booting


check both your power and video connections to the monitor, sounds more like a monitor power issue.
if the connections appear ok, but screen still blank, try connecting a known good working monitor from somewhere else and see if it works with your pc, if it does, your original monitor is faulty, if it doesn't, you have a pc video issue.
