This is a new story.
The problem reported : No display
C0nfiguration : Celeron 1 GHz, on an intel 810e based Abit motherboard, 128 MB SD RAM, 20GB Seagate HDD, 52x Samsung CDROM Drive running Windows 98.
No visible faults were found on the motherboard. The power supply fan and the CPU fan were both working. No beep form the system to indicate the successful completion of POST and there is no disply. The HDD access indicator is on.
Naturally, the first suspect was the system memory. Just to rule out he possibility of any peripheral making a short on the system, removed all the connections except the motherboard power and the monitor and restarted the system.
No difference observed. Then removed the memory and restarted and looked for any error beeps from the speaker. There were no beeps. Not even the usual click sound.
Checked the memory and CPU on another similar system. Both are working fine. CHecked the monitor also for any possible problem. that is also working.
Now the two remaining suspects are the onboard display and the motherboard itself. As there is no error beeps for indication, it was not possible to find out the real problem. The only option left was to ask the customer to replace the motherboard.
Before telling him the same, I got an urge to just remove the battery powering CMOS as a last resort. Just took the battery out, cleaned, put it back and restarted the system.
Viola! It started working. After making the required changes in the set up, the system booted and worked fine without any problems?
I am not sure exatly why it happened. Can anybody explain?
