Howdy!
I'll make it short: I've got a small laptop which has been running extremly slow the last few months and I've only now come to the decision of reformating it (if that's the correct term... Reinstall windows on it). The computer is running on Win 7 and the specs are the following (if you wish to know

):
Processor Intel Atom CPU N280 @ 1.66GHz 1,33GHz
RAM: 1 GB
32-bit OS
And that's all it says.
Now, the thing is that I've been pondering about if I should reformat it to just wipe everything out on the hope that it'll run smoother and faster, instead of cleaning it bit by bit (which so far hasn't had much result), and I just want to ask you guys if you think it's worth it, or if it'll just run as slow... Maybe due to that the computer might be old or just over-used.
And now, for the main point: the laptop doesn't have a CD-drive, I don't own an USB CD-drive and I'm neither in the economical situation to buy one. I knew about something called USBCD or something, that I tried to google but didn't really get any results, but yeah... Does anyone know anything about this or something similar that can help me wipe off my whole laptop and "reinstalling" windows clean?
Of course, all this, in a legal way.
Thanks a lot for the help, in forehand
