| 1316334 | 2012-12-05 00:00:00 | Why wouldn't you do that? The risk of being zapped by 230 volts of residual electricity, even when unplugged... |

| 1316335 | 2012-12-05 00:08:00 | Why wouldn't you do that? Because 99.99% of people dont have the skills to warrant opening up PSU's , just for a poke around/stab in the dark. If you dont have spare PSU to try instead, It would be a good guess that you dont have the skills to try & fix a PSU |

| 1316336 | 2012-12-05 00:27:00 | My original comment was a bit of a dig aimed mostly at pcuser42's reaction after reading Frank's comment, but reading his other posts especially this one pressf1.pcworld.co.nz(or-others)-abuse-it-does-not-wash I suspect he knows what he's doing. For anyone else... the charge in the primary filter capacitor(s) will likely have gone by the time you open the PSU anyway due to the bleeder resistors across them. If the resistors have gone open circuit or are not present then you may have a problem, but only if you're silly enough to go poking your fingers on the primary side components without checking the voltage first. If there is still a charge present, simply drain it with a 10kOhm or so 5-10 watt resistor and verify with your voltmeter. Don't just use a screwdriver etc to short the terminals or you can damage the capacitor, or weld your screwdriver to the leads. Following such simple precautions and it's not dangerous. Yes most people wouldn't have a clue how to repair one but even so, if they do feel the need to have a look (and some people will!) they should know how to do it safely, in my opinion. |

| 1316337 | 2012-12-05 03:29:00 | I'd check the CPU cooling fan to make sure it is clear of dust. I had this happen to me, and when I cleaned it, no more problems. |

| 1316338 | 2012-12-05 04:42:00 | One common symptom of overheating is when it shuts down, and it wont start right away. There are built in safety devices that wont allow the PC to restart again until the overheated CPU has cooled enough. If you have to leave it for a few minutes, then its overheating ( usually) If it starts right away, could be a faulty PSU, or some other fault. |

| 1316339 | 2012-12-08 06:15:00 | Many thanks to all for their input on this issue . Yes, it's been a 'pain' of an problem to deal with - especially when it shuts down when I'm in a hurry to get something done before I rush out the door to work!?! Of course some days it runs all day without any shutdown issue . . . . I have Speccy loaded so will run it later & post the results here . When it shuts down, I can restart it almost immediately & it often will run for 10 - 12 hrs no problem . Again, many thanks to all . |
