I am having a similar problem with a desktop version of the motherboard. I have determined that it is a motherboard issue. The whole computer locks up when the video goes dark. The hard drive controller gives a steady read light, the keyboard is locked out, CD-ROMs will not open, the reset button is disabled and the mouse is frozen. I have swapped memory, video, dis-connected all but the most essential internal components. The power supply is a brand new 450W PS. No luck.I am thinking that it may be an AGP issue but am unable to get a PCI video card to work in the system so I have not been able to check that theory out. Just thought that I would share so that you can compare your symptoms to others who are having similar problems

I was using my laptop suddenly screen goes off anad then i restart my laptop it's turn on but stop at first page with no clue or something show it,s on but with black screen, is it hardware problem?


first re seat your ram and check if not, disconnect your hard disk and power on, after the computer powers on you should get an error saying that your hard disk is missing or check bootable media. this should happen fast after disconnecting the hard disk. and if this is so, then it'll be that your hard disk is failing.

Open your laptop and and fix the hard disk cable.After this start laptop and check the bios if HDD detected then select boot device and select first boot device is Hard disk.Save the setting and restart the window.You are able to open your window. But If Hard disk drive is not detected change data cable,power cable of Hard disk.If hard disk is detected in bios follow upper rules. And if it is not detected again you should walk into Hard disk repairing center and check hard disk there.

My compaq presario c765tu laptop suddenly turned off while i was working with that.then when i tried to turn on, only the power light comes, fan moves and dvd drive opens but the screen remains off.nothing...


If the problem is with the RAM or Hard drive then atleast you will get the access to the BIOS and this is not related to the hard drive or RAM as there is no display on the notebook.
If the Quick launch buttons are glowing then perform the following:
1. Remove the notebook battery and disconnect the AC adapter. 2. Press and hold the power button for a minute. 3. Reconnect the battery and AC adapter then try to turn on the notebook.
If the display still doesn't appear then, connect the notebook to external monitor and check the display on it. If there is any display on external monitor then the issue is with the LCD screen. If there is no display on external monitor then the notebook needs to be diagnosed by a technician at the service center.

My toshiba laptop not on


Your laptop can be ON without hard disk but it will not boot anyway if the hard disk not installed.
You can enter the bios set up to check if the hard disk is not detecting or not working. or visit the nerest service center.
