I would have a hard look at the power supply. If you are familiar with using a voltmeter, measure each of the supplies. I put together a new system with a dual Celeron PPGA system with an Abit BP6 mobo, 128M memory, two Seagate Barracuda SCSI disks, SCSI CD-R, and SCSI CDROM. It worked fine at first, then started getting flakey. When I monitored the voltages, they were all low. I replaced the power supply and that fixed the problem. -- Russ Poffenberger Engineering Specialist Schlumberger Technologies ATE DOMAIN: [log in to unmask] 1601 Technology Drive San Jose, Ca. 95110 Voice: (408)437-5254 FAX: (408)437-5246 PCBUILD maintains hundreds of useful files for download visit our download web page at: http://nospin.com/pc/files.html
