Hi,\n\nI would be grateful for any ideas with a strange problem with my Compaq\nArmada M700. The computer suddenly crashed in Windows 2000 which had\nbeen running fine for ages. After a clean format and reinstall I found\nit was still very unstable. Just in case it was a dodgy cd, I tried\nformatting again and loading Windows 98SE clean. Again still unstable.\nSo next tried XP Pro which loaded ok, but again was erratic and\nunstable.\n\nWent into BIOS screens and it even froze on that! The cooling fan\nappears to be working ok so it is unlikely to be that although the\ncomputer always has got warm around the cpu/memory module area.\n\nAssuming the problems being due to RAM and/or hard drive, I have so far\ntried the following.\n\n1. Replaced the original IBM 6gb hard drive with the IBM 10gb which was\nworking fine in my Dell. Have run extensive diagnostics on this drive\nwhich passes every time and have even run the Hitachi/IBM feature tool\nand slowed the drive to UDMA 2 [ATA33]from the default UDMA 4 [ATA66]\n(which has made it slower but a bit more stable)\n\n2. Replaced the 2x32MB memory modules with 2x64MB modules. The other\nRAM is onboard. Total RAM 160MB now. Have also run extensive\ndiagnostics on this RAM which passes every time.\n\n3. Flashed the BIOS to latest version.\n\n4. Run compaq diagnostics and found that it failed on parallel port, so\ndisabled parallel port (and also serial port just in case)\n\nHave now tried all I can think of and am losing sanity. I hope it is\nnot the main board inside as this would be sad as the rest of the\ncomputer is fine (screen, cd, fdd etc.)\n\nHas anyone had a similar problem and do you have a solution?\n\nMany thanks in advance!
