My computer randomly crashed after I tried to open up itunes and now it is acting like a brand new computer that needs installation of an operating system. I am running windows 7 home premium 64 bit. Before it crashed itunes  was giving me an errors something about system image. When I clicked on itunes the 3rd time it opened the program but then froze my computer. When I tried to close itunes I got windows saying end process and I tried clicking end process but the windows were frozen. After like 3 min of being frozen I got the blue screen. I didnt read what the blue sreen error was and restarted my computer.Now everytime I power it on it ask for boot device. I dont what to do, please help. I am new to this forum so sorry if i am retreading an old topic.

You might try System Restore to a point prior. If that doesn't work open an elevated command prompt by typing cmd in search then right-click and

 

Run As Administrator and type sfc /scannow ( note space between 'c' and / ) and press enter. This will attempt to repair files if it can.

 

When it is done it will create a CBS log file. Then copy and paste: findstr /c:"[SR]" %windir%\Logs\CBS\CBS.log >"%userprofile%\Desktop\sfcdetails.txt

 

This will create a sfcdetails.txt to desktop which will show any files it could not repair.

 

From there open an elevated command prompt again and type chkdsk /f and enter. Then run chkdsk /r and let it run.

 

You can also try these options: http://windows.microsoft.com/en-US/windows7/What-are-the-system-recovery-options-in-Windows-7

I tried doing your instructions but they didn't work they kept on telling me to restart my computer, also I can only use windows 7 when I have install cd in the reboot part. I went into my bios and it doesn't recognize my hard drive, so I think my hard drive is not working. Is there anything I can do to get it working?

Do you have OEM disk? If so put it in the drive and shut down computer. Restart. It should display some options. One should be Repair Your Computer

 

highlight and press enter. It should give you an option for Start-up Repair. Select and enter. From there follow instructions.

 

I know you said you inserted cd but wanted to verify OEM.

Turn off and restart. Keep tapping F8 until you get menu. See if you can boot in Safemode or Safemode with Networking.

I hate to disagree with a learned colleague, but I'm going to !

 

Hurrikayn, the black screen with the the blinking cursor means the system isn't pointing at a drive with a bootable sector and the screen you keep getting to

Now everytime I power it on it ask for boot device

 

is the one you want to solve the problem !

 

I suspect it lists devices like (1) CD drive, (2) The type number for your hard drive, (3) Any other drives you might have fitted.

 

Use the up and down arrow keys to select your hard drive, then press 'Enter'. Your computer should now at least start to boot, and if you still have problems, then Sikntired's suggestions are on the money.

 

Best of luck,

 

Chris Cosgrove

Thanks Chris, completely overlooked that. Important thing is to get issue resolved.

 

The more opinions the sooner the resolution
