One of my kids machines has started fainting rather suddenly. It can be in the middle of something, then foof-dead, as if someone pulled the power lead out. wait a few minutes and it will turn on again. I suspect it may be a (temperature related) problem with the psu, but the curious thing is when it faints, the power LED commences flashing at a leisurely once per second, which is something I've never heard of. If I pull the power lead it still carries on flashing for up to 20 seconds, probably as a smoothing capacitor discharges.
Anyone ever seen this before, or got any ideas before I condemn the psu?
after work. I have 2 lying around. But I know one of them doesnt work. Problem is I cant remember which one :( That'll teach me to throw things out that I know are stuffed, instead of tucking them away somewhere for reasons that I cant even explain to myself!
Knowing my luck though, it will probably be the mobo thats on its way out. Still puzzled by the flashing power led though...
Thanks, but none of the above. I've left it on all night and its been fine. If I give it something to do then it falls over within a few minutes. ( I dont have a screen saver set, everything is permanantly on like hard drives and screen etc and hibernate is off as a matter of course because I dont trust a sucessfull wake up. But just to be sure they were the first things I went to check when the problem arose. Plus, it would not 'wake up', hence my comment about comatose mode.
but it seems like the psu fan isnt spinning as fast as it really should. I'm not going off noise, but rather the actual airflow when I put my hand over the vent. I think that before I condemn it I will see if I can open it up and somehow service the fan / bearings.
Might even be able to replace the fan. We'll see...
In the meantime I have unplugged all the other hdd's in an effort to reduce the load on the psu untill I can find time to look at it, probably at weekend at this rate. so far so good.
