PC Randomly Shuts Down
EHM-1703 Philip:
Iain, Get yourself a small tube of Silver based Thermal compound. (The best you can afford!) Get some cotton buds and a small bottle of IPA (Isopropyl Alcohol) from a chemist. Very Carefully remove all of the old Heat Sink Compound and replace it with high quality new compound. Don't over paste it either! If you are having overheating problems and you fitted it yourself, this will probably cure it. I will be surprised if it is this though. Every AMD processor I have had that overheated caused very strange problems to occur before shutting down altogether. (BTW, I have managed to overheat every CPU I have ever had, just by trying to find it's OC limits :) )
EHM-1617 Iain:
What do I do with the IPA?
EHM-1703 Philip:
Well I would advise you don't try drinking it firstly, it can cause instant sight loss! :P
Wipe off as much compund that you can with a dry lint free cloth. (Don't use tissues or kitchen towel as they leave residue) Dip a cotton bud in the IPA, press it to the neck of the bottle to effectively wring it out, then gently remove the excess paste from the top of your CPU with the cotton bud. Make sure when you press on the cpu, that the fluid does not run out of the cotton bud, it should just be damp. Leave it for about an hour after cleaning (Otherwise you will flambe your cpu when you power up again) and reapply the new compound and fit the fan. IPA is very strong alcohol based cleaner and evaporates quickly without residue, but it is conductive so don't use too much it or get it on your cpu contacts.
EHM-1617 Iain:
OK, cheers. Will report on progress.
EHM-1752 Luciano:
Hi Iain,
I had the same problem of sudden shut down about 2 months ago.
I eventually changed the power supply with a brand new. It was ok for a while, but after 10 days or so the problem occurred again. My repair shop decided to change the power supply again (under guarantee) and my PC seems to work all right now.
Hope it helps.
Bye.
Luciano
