From: frischmoutt on 9 Jul 2010 16:15 TXP4 Asus Mobo w/ a K6-200, running Win98SE, w/ an USB ADSL modem, playing the role of gateway / firewall. I don't have the intention to modify my configuration, needing to monitor the traffic. Changing the computer by a recent one is not an optimized solution, I don't need power. After 30 mn at 28�C room, the monitor began to display ASCII characters everywhere, ending with a BSOD. After 15 mn cooling, I rebooted. Same behaviour under DOS as well. I'm highly suspecting the graphic adapter. A thorough visual inspection didn't end with any issue. The capacitors aren't bulging but I can't say if they are dry or not. Prior to borrowing a bord to a colleague, I'd like to analyze more deeply the situation. Would the C-MOS be one of the reasons (the battery is a little bit above 3V) ? What else might induce this display corruption ? Thanks in advance

I see the board has PCI and ISA slots, so you'll likely need a PCI adapter. I have a PCI FX5200 for such occasions. The PCI adapter likely has its own memory on the video card, so won't be wasting any system RAM. I think my FX5200 has Win98 drivers, so the driver support goes back a bit. The TXP4 doesn't have integrated graphics that I can see in the manual. Sometimes, a video card fails, because the cooling fan stopped turning. Then the GPU overheats. Check the fan of the video card, as a first step. Paul

Used 4 to 12 hrs a day depending on the day Sometimes it had issues win 98SE but nothing of serious. The graphis adapter is PCI Ram equipped , no fan on it. The CPU fan has been replaced this winter and the dust removed. The question: May other computer parts (C-MOS, RAM, chipset, ...) induce such a problem considering that the computer is able to boot ? The answer might change my way to proceed with the repair. Bye

Hi, No fan at that time, the board has been bought in 1996 ! I also forget to mention that the computer case was always open and the airflow around it wasn't disturbed. The board probably died because of its age (~20000 hrs). Before asking around for a board replacement, I'd like to focus on all the possible causes. Thanks |
