Maybe it's time to try out Ubuntu Linux. If you have to reformat, I'd give it a shot. Or at the very least consider dual-booting. You won't be running into the speed and viral issues on Ubuntu and most applications on Windows still work on it (using Wine), albeit slower than on Windows.

Also, how are you doing stranger?

I'll probably have to resort to a reformat as the hard drive (when used as an external hard drive) gives an I/O device error which is probably meaning that all hopes of mines in salvaging my documents are fruitless. I might be considering in getting another hard drive (possibly a 250GB rather than the stock 100GB that came with the laptop), so maybe an option of mines could go to adding an additional OS. Only concern would be the drivers for the devices that are built-into the laptop.

Apart from the computer problems, I am okay. A few family problems, and my brother getting married earlier this week. A tad saddened through some of the other current events dealing with pop culture. But asides those, got a new car for practically a steal. Other than that, nothing really new on my end.

Um, you should consider it could be an overheating issue or a bad hard drive, unless you didn't scan the files you copy back or keep going to certain sites without big anti-virus and anti-malware installed you shouldn't be getting the same problems after reinstalling windows.
But with a laptop I heard about them easily getting infected and accessed when online via wireless because the connection hasn't been encoded and specific security added. (I don't know what exactly since I never had one, but I hear its a common problem most people ignored)

Other possibility is if you're using a damaged windows disk or pirated one, or they're all lemons or have incompatible parts or drivers.. Basically it might be something obscure.

Surprisingly, the only ones that actually had visible signs of getting hacked were the desktops of mines (2 out of 3 were hi-jacked). As far as I could tell with my laptop, it was never hi-jacked; unless it wasn't anything highly noticeable.

Overheating is probably a possibility to what is causing the problems. The stock hard drive (Seagate Momentus 5400.2, model number: ST9100824AS) I believe had the same problem a couple times before when I had to reformat the computer. I was looking online at hard drives and found other hard drives similar to the one inside my laptop but through customer reviews they say that the hard drive has problems with overheating. Though I'm uncertain if it's just the hard drive that came with the laptop or if it's all capacities on the line of hard disks.

As for a damaged or pirated copy of Windows, I'd hope not. The computers been stock apart from the additional RAM I had installed given to me by a friend to upgrade it from 1GB to 2GB max. I could entirely need a new computer however I lack the funds to attain a better mobile computer. I may have to go desktop over laptop as they're usually better performance-wise.

I have another friend here that always have problems with computers. I call him lighting hand XD
sorry that you got so many problems!
