Last night my computer woke me up! I had left it turned off and it started turning itself on and off randomly at intervals of about 5 seconds. When I tried to start it this morning it would cut out after around 2 secs then pause for a moment and start booting again. Eventually it made it to windows and is now running ok... My system: 300W Zalman PSU (connected to surge protector) A7N8X Deluxe mobo Athlon XP 3200+ 1 GB Crucial 120 gb SATA What is the likely cause for this? 1. Dodgey power supply 2. Loose cables to power button 3. Paranormal activity 4. Others? Thanks for your help! James
Are you located in uni halls and connected to there network by anychance, or any other large network for that matter? My freind had this happen to him with his pc, turned out that in the bios he had wake on lan events enabled, and someone in the uni halls was sending out wake on events, which caused his pc to power up, several times in a single evening, eventually he just switched it off at the wall, untill he learned that he needed to switch off the wake up events in the bios.
Now the system wont boot at all. It cuts out within a couple of seconds of starting. This must be a bad PSU right? I was thinking of the Corsair VX450W: http://www.ebuyer.com/customer/prod...hvd19wcm9kdWN0X292ZXJ2aWV3&product_uid=131052 Let me know what you think.
it could be a bad psu, but i don't think that would explain the random turning on. It may be a bad mobo though, its hard to say. Is there any way you can just put another psu in there to give it a try? PSU would probably be the cheapest thing though just to replace and hope its whats wrong.
probably the PSU, do you have a multimeter handy? if so make sure the voltages are within their proper ranges. I think it's the +5v (green wire? not sure) that's the power-on line. You should have +-5 +-12 3.3 (and a 1.8 I think)
