ok my parents have this old computer with i think a pentium 2. theyre too cheap to buy a new one and its running really crappy. i was gonna re-format it to see if that helps. but when i go to re-format the hard drive it says it cant be done because there are files in use by windows. ive never seen this before on any computer. what do i do? i was thinking of just taking the hard drive out and putting it into my computer and re-image it from there. to see if that would work but i have a feeling that wouldnt work.
