Toshiba c855 screen went black

SOURCE: I have a Toshiba A105 Laptop, Screen goes blank after windows....

Here are some easy things that can sometimes resolve this problem:
1) Sometimes there can be a static buildup on the mother board. Power off, remove the battery, remove the power cord and hold the power button in the on position for at least 30 seconds.
2) If that didn't work- Power down, remove the battery, remove the Hard Drive and memory modules and reinsert them. Try to power back up
If these things don't work, get back to me for some more ideas.

SOURCE: Computer won't boot Windows Vista. Screen goes black with cursor arrow.

In this case you have to do the PC restore . you can do that in dell machines by shutting down the machine and when it is coming back on just HOLD DOWN THE CTRL ket and the START HITTING f11 key in this case you will lose the data which you have the on the c drive but this issue will get resolved .

Else you can try to restart in the safe mode with networking and then go to the system restore and then select the bold dates in which you have idea you system was working fine . selct the date and then do the system restore . In this case you will not lose the data but you will lose the updates which you have done after that date .

in both the cases system will work .

It may be because of your hard disk damage or OS problem. Try to install a fresh copy of XP from a cd. boot from XP cd and install .

Acer Aspire One BIOS Recovery The AA1 has a built-in BIOS recovery routine, making it possible to flash the BIOS even if the system doesn't boot anymore. It's only meant for emergencies and may void your warranty, so use at your own risk.

Follow every step carefully!

First format an USB stick with FAT.

Download the latest BIOS, and put both FLASHIT.EXE and the BIOS file in the root directory of the stick. Rename the BIOS file to ZG5IA32.FD, that's important. Do not remove the USB stick.

Turn the AA1 off, make sure both battery and AC adapter are connected. Press Fn+Esc, keep it pressed and press the power button to turn the AA1 on. Release Fn+Esc after a few seconds, the power button will be blinking. Press the power button once. The AA1 will now initiate the BIOS flash, do not interrupt it under any circumstances. After a while the power button will stop blinking, and the AA1 will reboot shortly after. Wait patiently.

The BIOS has been flashed and all settings reset to default.

If for some reason you made a mistake during the procedure and it doesn't reboot by itself wait 5 minutes before turning it off, just to be safe that it isn't still flashing the BIOS.

Download WIN98BOOT.ZIP and HPUSBFORMATTER from the internet normal bootable like a diskette won't work with a usb stick
I had mine 2 months it's a common problem with the notebook.
The onely thing that you have to do is download these programs with someone with a internet connection.

Good luck

Windows Start-up Errors
Step one, you need a Windows Installation CD. If you only have a recovery disk set like the ones from HP or Compaq they will not do what you need done. Under normal circumstances however, you can use a Dell disk because the Operating system is on a stand-alone disk. All retail versions are also acceptable as well as upgrade disks. For a rule of thumb, if the disk has the Microsoft hologram it should work. You can order a boot up floppy disk from here:
http://support.microsoft.com/kb/310994 with this file, if you know how, you can use “ImageBurn” to burn the file into an ISO file which can be burned to a disk. Now make sure your computer boots to the cd rom first. If you know how to do this skip on down, if you don’t, while the computer is first starting up and you see the manufacturers splash screen, tap F12 (some computers it’s F9, others it may be another key, you may have to watch and see if the computer lists the key strokes for getting to the boot menu. If you still cannot find it, boot into the BIOS settings and change your boot order there. Save your settings and exit, the computer will now seek the cd rom as its boot source first.
Place your Windows disk in the computer and start it up. When you see the test at the top of the page “Press Any Key To Boot From CD” Just hit the space bar to activate. The next screen you will see will most likely be a Windows setup screen, when you see this press the “R” key to get to the recovery console. It will get there, it may take a little time, patience. Once it loads you will be given a choice of Windows installations, there should only be one, if there are more, always pick number one. It may ask for an administrators password, if you have not set this particular password, then just leave it blank and press enter. The next prompt you see is:
C:\Windows>
You need to type the following:
cd \
hit enter. Pay close attention to the spacing between the characters. There is a space between the character “d” and the “\”
You are now at the ROOT of the drive, this is where basic commands can be given and changed. You should now see the following:
C:\>
Now type the following:
CHKDSK /R
Hit the enter key.
The chkdsk /r command also includes the P command and will also look for lost recoverable information in bad sectors.
There are occasions depending on how corrupt the system is, that this process could take several hours, so be patient with it.
Now, after chkdsk has run type the following:
FIXBOOT
Hit the enter key.
It may prompt you with a warning, that’s ok, just continue. When fixboot has finished, type: EXIT hit enter and windows will reboot. When the system reboots, tap the F8 key during this time and you will see the multi-boot menu come up. Scroll to the title “Last Know Good Configuration” and hit the enter key. If you were having some simple drive errors this should have fixed them.
