Hi all. I got an ACER T180-GB7Z P.C with a Foxconn MCP61SM-AM, REV:1.0A motherboard. The computer will boot into Bios and you can use it as normal for a varied amount of time before the video goes off and the CPU fan stops spinning. The power supply however is still running and the heatsink overheats. This is also the case when booting windows.
I have tested the ram, 2 x 512MB DDR2 667 and it is fine. I have also tried one stick at a time in different slots.
I have tested the PSU, fine.
I cant test the CPU as I do not have another, it is an AMD Athlon 64 x 2 (AM2 I think) - ADA4200IAA5CU NDB4F 0638XPMW T071172I60256.
I have cleaned the heat sink and CPU and re-applied thermal paste. Done it many times and positive thats ok.
The battery is OK.
The motherboard only has 1 stick of ram when testing, the PSU, USB mouse, PS2 keyboard connected. It is also out of its case.
If I reset the cmos, sometime it will boot again in the same way, sometimes not.
If I try to turn it off at the power pins the CPU fan often goes full throttle.
One odd thing though, when the video goes off and the CPU fan stops, if you move the fan back a bit it moves forward a bit like theres still power there then stops. I tried changing the fan, same bleep!
Any help as always greatly welcomed, including intellegent guesses.

Phill.

Try a different board (temporarily) with same hardware...that's the only way I know to pin it down.

Louis, thanks, that would be the ideal thing but I don't have one or another CPU. All I really wanted from this post was what was more likely to be at fault as I don't want to buy something that I don't need. Oh well better get the credit card out!

Well...I would not act solely on my opinions and I make them .

For me, considering that a MB is bad is tantamount to considering a new system...something I seldom do. Act slowly.

The only way to rule out the PS as the problem is to use a voltmeter and check all the voltage rails to make sure they're correct
