windows 7 - PC Boots to black screen with mouse cursor
2014-01

I'm trying to repair a Windows Vista PC booting to a black screen with only a mouse cursor on it. I can move the cursor, but the PC doesn't respond to Ctrl+Alt+Del, Ctrl+Shift+Esc, etc. It seems to be on the verge of booting, but never gets to the login screen. I've tried the following fix actions:
- Boot into all forms of safe mode (with/without networking, command prompt)
- Boot to last known good configuration
- Boot with low video resolution
- Boot from Windows 7 installation disk (full license)
When I boot to safe mode, low vid, or command prompt I receive an "Operating System Not Found" message. So, intending to start fresh, I bought a Win7 disk and that's where things got weird. The PC does the exact same thing when I boot from the Windows 7 disk. I know that it is booting from the disk because I see the Windows 7 logo on the boot screen (the shiny blobs turning into a Windows flag rather than the green progress bar). I've checked my BIOS options and they are extremely limited, I can't really change anything except the boot device order.
I am at my wits end with this PC, can anyone provide any suggestions as to what I should try next? As many of the PC specs as I know are listed below if they are of any consequence. Any and all helpful suggestions I can get would be much appreciated, if you've ever had a mother-in-law you'll understand.
- Sony Vaio PCG-2J3L All-In-One
- Windows Vista Home Premium (again, trying to reload w/ Win 7)
- 4GB RAM
- Intel Pentium processor
UPDATE 8/8/12 The hard drive appears to be bad. Here's a recap: - Re-seating the RAM got the PC to boot from USB/Windows 7 boot disk - Hard drive is inaccessible from a SATA-to-USB adapter, will not mount from Linux, and will not complete the boot in Vista. Purchased a new hard drive and will replace.

Try re-seating the RAM. I know how stupidly simple that sounds, but you'd be surprised! However, be sure to unplug all power!!! Even if you think the system is off, it's NOT! So unplug batteries and unplug power cords just to be sure you don't fry your RAM when you re seat it.
Even more stupid would be to forget disconnecting all USB devices (less K/B and mouse). Hopefully, I don't need to say any more there.
Then check the BIOS which I believe you said you did. But I have a problem when you say all you can do is manipulate the boot order since that's not likely the BIOS settings. Personally, I've never seen a BIOS where the date and time couldn't be adjusted. So if you can't at least set the date and time then I'd bet dollars to doughnuts that you're not really in the BIOS. Typically, you press the DEL key shortly after powering on to get into the BIOS. But that key could instead be something else like the ESC key or F1, or F2. (Sorry, I can't recall what Sony typically sets it to.) And once in the BIOS you might want to pay attention to all areas related to RAM and CPU functions. This is a whole other area of discussion but just know that even one bad setting can result in a very sluggish system.
Next you might want to check all connections and make sure you don't have a failing hard drive or something. Cause from what you said, it sounds quite likely that your HDD may be on it's last legs. (Hopefully, you have things backed up too.) Then again, you may just need to re-partition and/or re-format (which will kill everything on it). So before you do anything else, you may want to check with the HDD manufacturer and see if there isn't a diagnostic boot disk you can get (usually by downloading an .iso file and then burning it to a CD that you then boot with).
One other suggestion might be to try booting a live Ubuntu CD (which is pretty much done exactly the same way where you download an .iso file and then burn it to CD that you then boot with). And in case you didn't know, you can boot to a fully functioning (although somewhat sluggish) system when booting from a live Linux distribution such as Ubuntu. So if you can at least do that much then it's almost a guarantee that you have bad HDD or some other SATA/PATA controller issues.
I can't say if any of that would work, but those would be my first steps. Good luck...

Problem: I am not able to open my laptop...nothing appears, just microsoft logo with loading bars. While choosing to go in safe mode also doesn't help, the same thing happen i.e. blank scree. All it shows is black coloured blank screen with the mouse cursor moving as per my mouse movement. I have read here that it could be a driver related problem, screen resolution, video card etc. But how to correct that if I am not able to open the computer? Thanks.

Can you boot from CD using a Windows cd? I suggest (and there might be a simpler solution) using another pc to download the latest gfx drivers for your gfx card and copy them to a flash drive.
I know the following works in XP, I can't remember if Vista had the option though I dont see why not....
When installing XP there's an option to hit 'F6' i think to install 3rd party drivers (look at the bottom of the screen and you'll see the prompt - this is on the initial blue screen when it's loading the setup files) . Use this to point to your gfx drivers on your flash drive. Try this for Vista. It should install your drivers.
The above should work if it is a driver issue. And if it works then you can slipstream the drivers into your windows installation - within legal limits of course.
