Hi, I have an old PC/AT computer that I have kept around thinking I would pull some data off it someday and that day is here. I managed to find all the cords and plugs (although the ps2/AT keyboard adapter doesn't work, hope Radio Shack has one). When I powered it up, everything seemed normal, only message was that the keyboard was missing which I expected. However, the big box/fan in the top rear of the case wasn't moving. I took the case off, swabbed the fan blades with alcohol, and even tried a little WD-40. Still no fan. I can turn it with force but it won't move at all on its own. Since I only want to retrieve some data, which I don't think will take too long, is it safe to run the computer with no fan in the power supply? What if I leave the case off, or use an external fan to cool the power supply? Obviously this computer is on its last legs and I don't want to invest any time or energy in repairing it. Would it be better just to pay someone to remove the hard drive and try installing that in another computer? Not sure the AT compatible drive could be installed in anything anymore. Appreciate any advice or suggestions! Thanks, Nancy
