When i turn onToshiba Satellite M100-JG2, get black screen,and hear 2 bee sounds,computer won't start.


Two beeps a generally a memory parity error.

Use a test utility like memtest86 to check it. Youll need another computer with a CDRW to create a test disk from an ISO.
Then boot the computer with the cd in and it should run from CD.

Beeping sound when starting


Usually when you first turn the power on ... it's usual to hear a couple of beeping sounds . And then, you may hear whirling/clicking sounds when your disk starts up (rotating) and your CD/DVD drive starts up, etc.. Then the monitor/screen lights up and starts to show the operating system (e.g. Windows) panel ... as it starts up.

If your system just beeps ... and beeps ... and beeps... and nothing else happens, the screen doesn't light up and show anything (for a few minutes), it likely the system is not starting up properly.

If you can clarify what actually happens, maybe I can offer more suggestions/information to help.

When I turn on my Compaq Presario V5000, it does not atart up rather some beep is sounded


That beep is a motherboard error code, depending if its one beep or multiple beeps it means a different error you can google motherboard error codes to compare your beep to the possible error codes to determine what the problem is.

My dell insprion 1520 wont go past boot screen it stars then goes to a black screen that says start up repair or start windows normally but when i click star up repair nothing happens then i pick start...


Place your windows cd/dvd in the tray and boot to the cd. When asked if you want to install windows, there will be a repair option further down towards teh bottom, or you will be asked to click R like before. The repair only works if the cd is in the tray.

System boots lights on "green" but screen stays black; even in save mode.


any beeping sounds if not then could be a video card error or just a bad backlight on the lcd screen. if you got beeping sounds than most likely a memory error

Computer dead and beeping


If it beeps and not boot then it is the post routine telling you there is a problem. The post routine is run when you turn the power on to ensure the computer hardware is ok to run. The manufacturer of the bios routine can tell what is wrong by the type, number and duration of the beeps. Look up the code meanings and it will indicate the problem. If this sounds like nonsense to you then give the make and model of your machine and what the beeps sound like. ( beep beep beep delay beep beep beep) etc. and I'll look it up for you.
