Whenever im on my laptop and playing SC, and i leave it for a moment, i come back to find it logged off
Or, While im playing, it will show a blue screen with a bunch of words and shut down before i can read the first word
Does anyone know whats wrong and/or how to fix it :\
This may be vague, i really suck at describing things, but if its a common problem it shouldnt be hard to know whats wrong ._.

Sounds like issues with drivers, you're getting BSoD'd on Starcraft.. Can you play other games without this problem?

Give me a sec, only other game i have is HoN, should i try it with that?

Yeah, basically you're just trying to figure out if it's a problem with your video driver at this point. Have you tried updating your video driver?

Whats a video driver? o.o
And i found out that it crashes with the following(currently):
Hon
Starcraft
Toontown
mirc
and even if i dont run a program, it just randomly shut down a minute ago
Another thing to note, all of these problems started after my brother dropped the laptop, could it be something in the laptop thats broken?

He dropped the laptop?! Get HD Tune and do a scan of your hard drive to check for corrupted sectors, it seems to me that what's happening is your hard drive has gotten messed up from your brother dropping it and the spindle hitting the platter, corrupting some data. Games are a bit more read-write intensive, so that may be causing it, and perhaps there's a file used in video processing that got corrupted, I don't know, but I'd run a scan across it, and check for corrupted sectors.

If it's not too much or none at all, open up the Run dialog and type "chkdsk /r" without the quotes, it will ask if you want to scan on next system start, hit Y, and the dialog should close. Restart, and it should run a scan on your hard drive, this will hopefully find and correct the problems on the hard drive, if problems persist, a fresh install of the OS may be necessary(corrupted OS files) or the laptop may need a replacement hard drive.

System (win+pause/break) -> Advanced -> Startup and Recovery -> Settings -> System Failure -> Uncheck "Automatically Restart". This will let you see the system error. I don't know where the default saves to. It's probably c:\windows\minidump or somewhere around there, but I don't think I've had any system failures in 5 years on any of my computers.

A video driver is the driver for your graphics card. In laptops it is an integrated graphics processing chip, or "GPU". Discrete graphics are found on desktops and high end laptops, and are generally much more powerful and require more cooling. A driver is a set of instructions for a piece of hardware to work correctly on your computer. Generally questions like "what is a video driver" can be solved INSTANTLY by typing the question into google. That's probably the smartest thing you can do in any situation when you don't know what the word/phrase means.

Back up your important data quickly. There's a good chance it is corrupted, and if it does fail you will have a hard time getting any of it back. It's not impossible (booting into linux will probably be able to keep the drive stable long enough to get the recoverable data off of it), but it's obviously difficult for newbies and can cost a lot of money for a simple process of data recovery.
