A week ago I started getting triple "beeps" like a component/board failure or (?), and a black screen.
After a few tries it would start and seemed to run okay. This went on for several days.
Two days ago, I hit the start button and got a bezel light very briefly, then nothing. Dead silence. Pressing 'start' .. nothing .. unless I unplug the power for a few seconds. Then I get the same symptom = fans just start to turn (not even 1 rev), then dies again.
I tried unseating and replugging VGA and RAM. No good. I started to try a spare power supply but the main board has one of those 24 pin power sockets .. where the 20 pin plug and 4 pin plug nest together.
Someone suggested that it might be the main board battery.
Monitor is okay .. (backup machine.)
It's a long way to the nearest "good" 'puter shop? But if I know for sure what the problem is, I can get a friend to buy the part(s) in BKK and EMS them to me. (Computer is too large to EMS.)
What does this sound like to you?
It really sounds like a failed power supply to me, but it's hard to say with any certainty. If you have any components from a good machine that you could swap out that would be the best initial troubleshooting you could do in your situation.
I don't think the system board battery would be the cause in this case. That's normally just for keeping the computer's time and BIOS settings.
I broke down and drove it in to the nearest local shop today.
It isn't the:
I'm thinking it may be a sensor on the main board / cpu that shuts down the system when the CPU overheats and it's giving an "overheat" signal on startup.
I went through the mainboard manual and could not find any beep codes .. so it's back to BKK via a relay meeting in Hua Hin .. *sigh*
Did something similar to open the DVDRW and recovered a CD that was stuck inside.
It's about 90%(?) that it's a failed main board. I happened to get one .. ASUS P5PL2/C .. that is said to be "not so good" .. around the forums.
