I have an acer extensa 391c P133 laptop which performed flawlessly for many years. About a month ago, while I was in the middle of a direct cable transfer between this laptop and my desktop, the laptop suddenly crashed. The computer has stopped functioning normally since. The PC generally just freezes up after a few seconds in the boot up process... both with Win95/98, MS-DOS and Linux, from the hard drive, bootup floppies and CD-ROM drive. In two occasions, last week, I was able to boot it up twice and the computer surprisingly functioned normally for up to 15 minutes at a time. In the first instance, it did in MS-DOS and I could repartition and format the hard drive, then it gave up again in the usual fashion and would not boot up, even after about 15 tries. A few days later, it did work briefly again giving me the time to boot up a Linux installation CD, create Linux partitions and go into the installation process for about ten minutes, but then froze up again after giving a segmentation fault warning and resumed freezing after a few seconds in the boot up process each time I started it (I tried at least about twenty times...) I would exclude a battery problem, because this behavior happens both when it is powered by the battery alone and when I use the external plug-in power supply with no battery in. Also probably not a faulty RAM problem, since I tried switching around simms and even tried with a new one at the local store, with the same results. Perhaps a CPU problem? What should I do at this point to make it work? Please help. Thanks, Nicole
