We run a peer-to-peer network of 8 PC's, most using Windows 98SE. One PC has recently developed the quirk of sporadically becoming extremely slow--a mouse click can take several minutes. The hard drive light flickers during this time period. This PC also acts as a server for an Access database and it serves this function fine while waiting for a mouse click to complete.
I have done a DiskScan and Defrag to no avail. I have done a virus scan, not finding anything. I have used MSCONFIG and PC StartUp Cop to see if anything unusual is running--everything seems normal. I have done a port scan to detect open ports--none are open.
Any suggestions of how I should proceed now?
