Help! PC shuts down abruptly!

[Tejstar]

Ok thanks guys - that puts my mind at ease!

[Tejstar]

Quick update - installed the new PSU and all seems to be well again! Thanks for all your help!

[Tejstar]

Oh dear - the PC was running fine this morning and now it is dead again!

Surely it can't be the PSU again, I've only just replaced it!

Any ideas?

Check the fan on the CPU is working and that it's not all clogged up with dirt.

Also check for bad capacitors on the motherboard. These are the little cylindrical things that stick up from the board. The tops should be flat & silver in colour.

If the tops of the capacitors are bulging or have any yellow / orange goo oozing out, then they are knackered.

Thanks mate - will try this later.

Last night I opened the case and fiddled around with a few parts, put it all together (didn't remove anything) and now it works again!

I checked the caps yesterday too and they all seem fine. I think I'll give the fan a clean and see how it goes. Although, I'm thinking of just buying a new one to save the headache...

Try to get some software that will monitor the CPU temps. Speedfan might do the trick, but it might not...

Edit: Just re-read the thread - you could use ASUS's own Probe software too...

I had this problem before and it turned out it was a faulty kettle lead.

Any chance you can change the kettle lead ?

Thats worth a shot, cabling inside could of broke loose or something.

Thanks - I installed Speedfan yesterday and the CPU temp seemed to be between 50-60C, which I assume is okay?

If it plays up again I'll try a new one - thanks!

50-60c is not okay really. ideally it wants to be around 30 - 40C. so it looks like a new cooler is in order. this should keep it nice and chilly

If that's under normal usage, then it's absolutely fine, no worries.

Limit is 85C for that CPU - speedfan can log temperatures so keep it running and if you get a shut down look at the last temperature before it crashed.

[Tejstar]

Cheers guys - how do I enable speedfan to log my temps?

[kalniel]

I think it does it anyway, but if not just have a look at the tabs, I think it was fairly easy. Then just find your speedfan install directory and the log's in there somewhere - I'll be more specific when I get home and can actually check, sorry!

[Tejstar]

Ok thanks mate - I'll have a look when I get home. Can't be that difficult...

I've been having a similar problem. After it's switched off, it doesn't always turn back on but when it does, there is no Windows message about a problem at shut down and checking files etc. Is that relevant in deducing the problem?

I opened up the case up and managed to turn it on and both fans have been running. Any thoughts?

[Tejstar]

Mine doesn't give any message about sudden shut down either…
