Back in the summer I could power off my computer and come back hours or
days later and turn it on with everything being fine. A month ago,
maybe when the weather started getting cooler, the system beeped at me
when I turned it on. I found that the fan speed monitor was set for a
fan speed higher than what was running and that the changing the fan
speed lower limit to allow it to spin slower would keep the warning
beeps quiet. If figure that this is OK since the hottest thing in my
system, even during the summer, is only 44C. After saving my change in
my BIOS all was well, that is until weeks later when I shut down for a
couple days again. The beeps were back and my BIOS seemed to need to be
rewritten, and all was OK again, or so I thought. I shut the computer
off while out of town for the weekend. Now it won't power up again.
This time it won't even activate the monitor, so I can't get to the
BIOS.
Help? What can I do?
My system motherboard is an ABIT AV8-3rd Eye running an Athlon 64-X2.
My previous system had a similar problem, but it was more intermittent.
Initially, on a reboot or cold boot, the monitor would indicate no
graphics signal. However, if I'd remove and replaced the graphics card,
most of the time the system would boot normally. Ah! Bad graphics card
or oxidized contacts or shorted contact. I replaced the first, cleaned
and checked for the other, but the problem continued. Fortunately, the
MSI motherboard had 4 POST diagnostic LEDs on it, and by seeing which
ones were lit and which were not, one was able to narrow down POSTing
issues. (Something, I had forgotten about after 5 years of using the
system and never having anything go wrong.) They indicated a CPU
problem. At first, I thought it might be overheating, since the system
would turn off abruptly as if there had been a power failure. I removed
the CPU and cleaned the heat sink. Cleaned everything, in fact, but the
problem persisted. I thought, maybe, bad power supply, but all the
voltages were within specifications. I replaced it, anyway. Still the
problem. Ultimately, I replaced the CPU and the problem went away. It
was a slowly failing CPU.
I suggest with your system to check the power supply first, the cheapest
thing to replace. You could have a bad RAM chip, bad graphics card,
etc. Hopefully, it's not a bad CPU.
