here is the deal, I had a less than one year old Dell inspiron 64 bit windows 7 machine, 500 gig hd. My son spilled water on it and fried the motherboard, but had it checked and the hard drive is fine. I was wondering if I could install the hard drive from the Dell into an older Acer we have. It would fit Ive tried that but would it run? Here are the stats for the Acer. Model aspire 5515, total amount of ram 3.00, 32 bit operating system, # of processing cores 1, 64 bit capable Yes, AMD 64, ATI Radion x1200. Let me know if you need any other info..
