kingv Posted October 31, 2006 Share Posted October 31, 2006 Athlon XP 2200, Antec Sonata, ASUS V9480TVD, Seagate Barracuda. Built the system about 2 years ago and the first year was trouble free. Started experiencing random reboots where the BSOD was visible for a split-second. WinXP, in it's infinite wisdom, reported the problem as an unknown device driver error. Tried some minor troubleshooting. Pulled the sound card in favor of onboard, then disabled onboard, etc. Over time, the error frequency steadily increased until the system was practically unuseable. It takes about 60 seconds to get from the end of the POST to the WinXP screen. After one failure, WinXP decided the error was caused by the drivers for the ASUS video card. When I tried installing drivers from ASUS, the upgrade failed, returning the message...A parameter is incorrect. That was helpful. Tried swapping the video card out with a TNT2 M64 card. Same failure installing drivers. Somewhat satisfied that my video hardware is OK and fairly annoyed with Windows, I booted Knoppix (5.1 I think it was). The boot was clean and once KDE loaded, I ran dmesg in a terminal session. Everything looked OK. Went into the KDE InfoCenter and started kicking hardware. Everything there was OK until I ran the IO Ports test. The app crashed. I ran dmesg again and got an oops this time. A friend who's a Hardware Engineer interpreted the results for me as..."the system was trying to access memory-mapped IO in the motherboard hardware range and got a response it couldn't resolve"... Pulled all 3 XMS3200 512 sticks and booted Knoppix with one stick at a time. Two of the sticks booted OK, though the IO Ports error was still reproducable. One stick wouldn't boot at all causing a kernel panic. I was advised that even though the one stick wouldn't boot, it wasn't necessarily bad. It could be at the edges of it's latency spec and a questionable memory controller may not be able to deal with it. Back to Windows. Re-installed original video card. Looked for a BIOS upgrade that addressed memory issues. Upgraded BIOS to ver 1.09 I think it was. No difference. Windows would boot successfully maybe one time in 20, so I was unable to boot each stick individually as I had in Knoppix. Changed BIOS setting for memory frequency from SPD to Auto, Windows found new hardware. PCI memory, and nVidia memory controller which it installed succesfully. Still can't load video drivers for any card I try. My gut feeling was that I had some sort of hardware failure seemingly independant of the OS so I RMA'd the board back to ASUS. They're telling me the board is A-OK. Now I'm here. All memory was purchased through ZipZoomFly, though I can't locate the receipt for one of the sticks. Set up interim tower, ASUS video card confirmed healthy. I have no other system that I can use as a test pig for the memory. Would like to send all sticks back for proper testing but will follow any guidance you may have once I get the board back from ASUS. Thanks very much for your time.
