    yes, the F5 is for monitor selection.thanks for the help but I'm afraid i have deeper troubles. its not the fan making noise but the primary HD (there are 2HDs) itself...gotta spend some money($65 for 60gig)

Perhaps it is trying to power an external monitor. Try this: Once your computer boots up, hold down the "fn" key (usually bottom row of keyboard) and then hit the key that shows what looks to be a monitor on it. Usually on the Toshibas, its the F5 key. This key will always be in the F key row. Let me know if this helps.

MY WINDOWS 7 WONT LAUNCH.....JUST GOES TO A DARK SCREEN


Try pressing F8 when you switch it on and try to boot into safemode, if that works come back to me. Does your model have the ATI Radeon Graphics?

Compouter will not start up. When first turned on, I get the Dell Inspiron screen with the bar under the logo, then the screen goes blank for a second and then all there is is the curser in the upper left...


You can try to boot to safemode. When you turn on system as soon as you see Dell logo keep tapping F8,select Safemode under advance boot option. If you we're able to log in to your account you can try to uninstall video driver and restart the system to normal mode then reinstall the video driver.
If you we're not able to boot to safemode , you can try to connect to external monitor toggle to FN+F8 if still not showing anything might be a bad video card.

this problem might be due to the corruption of logon file
install a fresh copy of windows or try to restart it in safemode by pressing F8 repeatedly before boot screen.

My lenovo t60 screen goes black 15 seconds after


Hi, try to boot into safemode, turn your system on then keep on tapping F8 to get the windows advance Menu screen, select safemode.

In the safemode windows go to Control panel and check your power options, you will see what time frame your system has for the LCD when turning off.

If this does not fix the issue, try booting into safemode with networking for you to be able to go online in safemode try updating your BIOS from your Manufacturers Website, Updating your bios may fix the issue.

Screen goes black. the power light is on, but the picture goes out. if i turn the power off, then on again it comes back for about 5 seconds, then goes black again.


Check to see if this problem follows in safe mode. Reboot and when the Dell splash screen comes up tap F8 until you see the multiboot options. Scroll to "safe Mode with Networking" let the machine boot up and see if you have a screen. If you do, right click on the desktop and set the resolution to 800 X600 and reboot normally. Usually when a screen goes blank in normal mode but shows up in safe mode means you have an incompatible resolution for the monitor or graphics adapter. This may be a driver issue or hardware. If the screen boots up in normal mode at the lower resolution, then try and go to properties again and bump the resolution up a bit, if it blanks again, try to go online and update the driver for the graphics chip.

Blank screen


hit ctrl alt del at the same time, when the task manager comes up, click on the applications tab...Then choose "new task" type explorer.exe into the box, this will launch windows explorer which is your desktop. If this does not work, type f8 at startup and boot into safemode. In safemode, choose start, then run and then type in chkdsk then restart the computer and let the check disk command process.

Screen goes blank


Try to load to safemode by restarting the pc and hitting F8 before loading the windows, after you load to safemode right click on desktop screen and hit properties and check if you change the size of screen?or the setting there? also look for the device manager of your vedio card and check if it works properly.
If all this not working this means your vga converter has problem this is card inside your laptop mostly happen with dell laptops, if you donot want to change it now, try to see if you have external screen port and connect your laptop to external screen.
Let me know wat happen?
