I have a system that has an Epox EP-MVP3C motherboard with Via AGP chipset, AMD K6-2 (100MHz) 500 processor, 8.4Gb Seagate Hard Drive - Windows 98 operating system. I have also tried Windows 2000 to see if it corrects the problem. No luck. My problem is that the system keeps locking up. Sometimes on boot-up - sometimes when trying to save a document or spreadsheet. I found some discussions that it may be a problem with the video card - changed that - no help. Some say - keyboard issue - changed that - still no help. Any suggestions.
