Windows 7: black "blank" screen upon boot up

black "blank" screen upon boot up

a week ago i began having slow down issues with my computer after updating, i soon realized that the antivirus software i was using had updated but was not scanning properly(comodo). i took the slow down as a sign that my computer may had virus's running a mok in it so i began to pull what files i could safely off, since i had not done so for that months work. i was able to only use the computer at "half speed or slower" in safe mode, since booting in anything other than would cause it to stall up and just show my desktop and a frozen taskbar.

after being able to recover most of my simple picture data, i went onto larger video files and soon found that i could not get passed (approx) the 15-20% download before receiving a error code 0x8007045D. my computer issues then began to worsen.

it got to the present point that upon booting up, i would recieve the "toshiba" window, then a _ that would blink for a few then resize to a smaller _ and then blank screen

i cannot even trigger the "safe mode" boot up menu it seems. i have ran a memory diagnostic by hitting the f9 button(or any button it seemed other than f2 or f12) which would run through both parts of the test and get to 99% of 2 of 2 and then seem to stall for 15-20 min then go blank.

i have just recently been able to make a disc using a friends toshiba that also runs windows 64 bit like mine, and upon the first time putting the disc in, i got the "click any button to boot from disc...." phrase(not exact but you guys know the wording)

i hit space bar and the files loaded and i received the microsoft bar and then a screen asking to choose between the toshiba recovery or a windows 7 system repair. i accidentally clicked the wrong key and chose the toshiba recovery, which then spat out the disc and requested a different disc that i have no clue was. i tried canceling, which then brought me back to the toshiba boot screen, followed by _ screen and then blank....

i have re tried to get the selection screen for the recovery/repair, but have not been able to. every time i have boot from disc it has gone through the files screen then microsoft bar, then black screen with cursor, at which it responds to mouse movement(touchpad) but nothing else.


help?

try the following and see if you are able to boot from the CD/DVD again:
Note: backup any files if you are using a RAID controller of any kind.
1. Go into your BIOS and load default settings to clear the CMOS memory (this will reset your RAID configuration resulting in loss of data, so if you have RAID and want to proceed from step 3, that is fine).
2. Save Settings and exit the BIOS.
3. Shut down and turn off the computer.
4. Unplug the computer from the wall or surge protector (then remove the battery if it is a laptop).
5. Hold down the power button for 30 seconds to clear the software connections between the BIOS and hardware and clear any corruption in the temporary memory.
6. (If it is a laptop, plug the battery back into the laptop and then) Plug the computer back into the wall.
7. Turn it on to reinitialize the software connections between the BIOS and hardware.

any chance of being able to save data off of it?
i could dump my files onto a friends external and use the one i have to act as the computer so that i can access the other hard drive, possibly?'


als, no clue if i have a RAID on it, but knowing my luck of the draw, i do.

Typically, you would know if you had a RAID on it because you would have either set it up yourself or you would have ordered a computer with one built in on purpose. They're usually set up custom during ordering.

As to getting data off, there are plenty of methods for doing so. The best would be to get windows system recovery up and running. You can use Advanced Boot Options and select Repair Your Computer or you can use a Windows repair CD/DVD to get to System Recovery Options and use the command prompt. From the command prompt, you will have to find the drive you want to copy from and the drive you want to copy to.

The best way to find the two drives is to type the commands that follow into the prompt.
C:
dir
D:
dir
etc. until you see your folder system listed for whichever drive you are looking for. Once you have done so, use the command that follows (I'll assume the drive you want to copy from is C: and the drive you want to copy to is D:, so replace C: and D: accordingly)
robocopy /s /r:5 /w:0 /xj /xo C:\Users D:\UsersBackup
Run the same command with any other folders you do not want to lose. For instance, use the command
robocopy /s /r:5 /w:0 /xj /xo C:\Folder D:\FolderBackup
where Folder is a folder you want to backup.

I had the same reaction the first time about holding the power button down for 30 seconds. An electrical engineer explained it to me: you are closing the circuit so all capacitors are able to expel the power built up within.

Can you create a windows 7 repair DVD on another machine. System Repair Disc - Create It has to be either 32 bit or 64 bit depending on what version you have on your computer. There is a site where you can download them as well, but I will have to look for it for you if you need to go that route.

If you want to download the discs, scroll to the middle of the Windows 7 Repair Disc Instructions and Download page to find the repair disc iso download links.

Alright, looks like you will have to recover your files using PartedMagic and moving files by mounting the drives through the mount devices on the desktop and move files across.

Go to the download link and download PartedMagic as a boot CD ISO. Then burn the ISO to a disc. Put the CD/DVD into your laptop and see if you can boot into PartedMagic.

Plug in a drive to backup your data to. There is a drive icon that says Mount on the desktop of PartedMagic. Mount your drive you want to get the data off of, then mount the drive you want to copy the data to by right clicking that icon and choosing the drive to mount. You'll have to open each folder/drive to find the right drives and copy the folders you want to the backup drive.
