Could this be a CPU issue?
LockedHi…troubleshooting a system and have come up against a wall. Hope you can help.
Celeron 533 (PPGA)w/cooling fan, Tyan S1854 mobo, 128MB PC133 SDRAM, 300W PS in mini-ATX case, Stealth III S540 32MB AGP video, 8GB Quantum Bigfoot HD, Win98SE, PS/2 mouse & keybd, 48X CDROM.
Trouble began when system would not complete boot. Powered on but no display and no HD or FDD access. Discovered that system would boot normally as long as keybd was disconnected. Cleared CMOS, no help. Contacted Tyan who offered to repair mobo, presuming it was a short somewhere. Board was returned, same issue. Contacted Tyan AGAIN, technician explained it was the chipset located very near the AGP & PCI slots which had pins touching whenever card was installed. I requested that the board be completely replaced with a new one to alleviate problem. Tyan tech agreed, board was returned AGAIN. When board was shipped back, same problem, and it was the old board (not a new one as requested) so I opted to try buyinga new mobo and to deal w/Tyan customer service later.
Purchased Iwill VD133Pro mobo. Set up system, now system won’t boot normally even with keyboard disconnected. Same problem, semi-boot but no disk access. Replaced power supply with a known good one – no help. Removed all PCI cards from system & replaced AGP video with a known good one – no help. Replaced AGP card with PCI video – no help.
Since I’m not getting any disk access, my question now is whether the CPU or RAM could be malfunctioning, and if these symptoms are indicative of this. I’m planning on grabbing a CPU from a local shop to try and replace to see if that works, but I wanted to throw this out there to see if anyone has a different approach to suggest.
