Good evening everybody,


I have this laptop that actually belongs to somebody else.  One day, it wouldn't load correctly, and to make a long story short, I decided I'd try to install Windows 7 on it (it originally had Windows 8 or 8.1...not sure but I think 8).  After changing UEFI boot to CSM boot, the main monitor of the laptop refused to turn on, and I thought it was a hardware problem.  Months later, I tried connecting to an external monitor and it worked fine (unfortunately it was without operating system).  Consequently, I installed Windows 7, but it was impossible to show anything on the main monitor (even looking in Screen Resolution and detect monitor and all of that, it didn't even recognize that it was there...).  However, if I revert to UEFI boot, the main monitor works, but won't boot into Windows 7 due to the different hard drive structure.  I tried many times, supposedly making Windows 7 boot images able to boot in UEFI boot, but to no avail.

Then I decided to try with Windows 8.1 (not sure how to legally get Windows 8...).  I installed it and everything with UEFI boot, GPT and all of that, and it installed fine, loaded fine and everything.  However, while I was in the process of downloading graphics drivers, the whole screen went black, and now it flashes on and off, occasionally showing just the cursor, and it doesn't show anything else.  Ctrl+ALT+Delete doesn't work, Escape doesn't work, the Windows key doesn't work...nothing does anything, and as I said, it just keeps flashing on and off.  I reformatted it AGAIN and tried installing the driver first thing, but before it could finish, all of this started again, and I don't know if it finished or not.  I waited 20 minutes or so and restarted it, hoping the driver was installed...and it continues flashing...

Now I have no idea what to do...looks like Windows 7 is impossible for me to install...and 8.1 doesn't want to work either...and there's no way I can install any programs for dumps or any drivers or anything like that.

Please help me.

Thanks for any and all help!

Sounds like hardware to me.  I don't have any suggestions, as there's really no way to test video on a laptop that you haven't tried.

I'd post over in the Internal Hardware forum to see if the experts there have any ideas:    http://www.bleepingcomputer.com/forums/f/7/internal-hardware/
