|Hello Everyone From Computing.net:|
I am having a bit of a crisis... I have been working on this particular computer for nearly 3 days now without any positive results. This particular machine I am working on seems to have been custom built due to the lack of manufacturer paraphernalia over the chassis and I have been unable to power on the machine long enough to actually look into depth the machine's components...
I can tell it consists of a single-core Intel based processor, 1 GB of RAM and Windows XP Media Center Edition Installed on the hunk of junk.
Basically my problem consists of the constant powering off that tends to occur mere seconds after I power the machine back on. If I let the machine sit for a good hour or so, it will stay on long enough to allow the Windows XP loading screen to show up then power off, but if I try to power it on again in succession, the machine just barely gets past the initial screen. America Megatrends is what it says at the top... I'm assuming that's the maker of the motherboard???
Nevertheless, allow me to explain what I have attempted to remedy the problem:
1) I have blown out the machine of any dust and debris carried within the chassis, on the fans and the heat sync, and all over the motherboard. I completely disassembled the case and took an air compressor to it
2) I suggested to the client that it could be a power supply issue, so she went out and purchased a new power supply. Went from a 350W to a 400W. The fact of the matter is that it is a new power supply and so it's age is irrelevant.
3) Checked the integrity of the fans in the case. Processor fan and static fan are both cleaned and functional... it's circulating air just fine... left the case open for a bit and tried to get it to run to see if an overheating issue... but same results...
I've checked over the net and it seems every "powering off issue" is unique in it's own way and I came across this site multiple times in my search so I thought I would sign up and ask the question. Do you think you could help me in my case? I hope I have been thorough enough with the information I have provided... there is very little more I can gather at this point I think. Thank you in advance!
