Computer freezes when bottom is impacted.

(I want answers, not OMG YOU'VE BEEN DEAD)
When ever my Acer Aspire one d250 netbook's bottom is impacted, or dropped on my bed, it freezes. The only way to restore it is to manually restart, then it usually freezes after the splash screen. Occasionally, it will just freeze. I've tried checking the temperature of the cpu, but it comes up as normal, 110 degrees Fahrenheit. I want to crack it open and check out if anything is loose, which would make perfect sense, but I want to do a system backup first, and I'm afraid it'll freeze during that. If anyone could provide links to instructions on how to open such a computer, or a solution to the problem overall. Also, I checked my ram already, and did a full scan with avast and AVG10.

I believe the problem to be that the hard drive is failing. As of now, my computer will randomly lock up, particularly during intensive HDD usage. When i drop my laptop, it'll lock up because the hard drive shakes and gets unbalanced, causing it to scratch. My computer will lock up randomly because it'll hit some of those scratches. This is all my reasoning. I'm not sure if it is right, but it seems to be. I'm going to do a backup and restore, just to make sure it is a hardware issue, and if it is, I'll get it checked out. Thanks for the support. 

I took it in and the problem proved to be a tiny crack in the motherboard. Lucky for me, however, my family just received a brand new desktop! WOOHOO!

Many hard drives have a gravity accelerometer sensor - and when they sense freefall, they lock up the hard drive QUICK to prevent damage -- this results in the operating system halting to stop it from attempting to write to the drive. Your laptop is performing normally and is trying to protect itself. Don't drop your laptop.

It wouldntt make sense for the problem to be that. It's just a gentle toss onto my bed, maybe 1 foot up in the air.

"once it detects freefall" a toss involves being AIRBORNE, in FREEFALL. that's the purpose of the sensor ;) It's constantly detecting gravity as an acceleration, as soon as it starts falling that force disappears and it panics.

Don't drop the thing - it's bad for them.

I don't drop it on hard surfaces, just my bed which absorbs most of the impact.
Obviously not enough.

Probably the hard drive is failing. Dropping any hard drive or moving it quickly in any direction, while it is running is bad for it. The hard drive acts like a gyroscope so when it is running at full RPM's, it resists moving. This puts strain on the control arm with the read heads on it. The heads impact the platter surface and can be damaged or even damage the platter. If you keep doing this you weaken the structures that align the heads and they have a difficult time finding where they are supposed to be in relation to the platter. The flow of information is interrupted and as a result the computer locks up. If there have developed bad spots on the drive platter then whenever the heads try to read it they once again get lost because there is no longer any info there. I have seen this done to many I pods with the small hard drives. Kids throw them around thinking its perfectly alright and then the things die. You need to get a replacement drive and clone it over before the drives totally quits.
Heat has nothing to do with it, its a hard drive problem caused by rough handling.

Thanks for the info. When i was in search of answers, I never got anything like that. How should I go about getting a replacement drive?

Bouncing a machine is never a good idea. My first advice would be "If it hurts when you do that, stop doing that."

A system backup is always a good idea. Just make sure you don't bang the machine while backing up -- put it on a table, or the floor, rather than your bed. If the backup does fail, try it again; a failed backup attempt won't do any harm.

Opening the machine... Websearch for "open repair Acer Aspire one d250" finds some tear-down videos and photo essays.

As to whether there's anything you can do once you get it open: If you are EXTREMELY lucky, reseating all the cable connectors may solve your problem. If not, odds are that you will need expert assistance. Laptops, and netbooks in particular, are designed for compactness and manufacturability and price, not for maintainability. You can try tapping lightly on different parts of the machine to see if you can isolate the freeze to a particular board or drive or cable... but the usual way to fix these things is to swap out FRUs ("Field Replacable Units" -- big things like motherboards or drives) rather than to try to trace and repair detailed circuitry.
