Solve : Computer shuts down upon Startup? |
|
Answer» I just fixed a previous problem with my new system, by RMAing the Motherboard. It now will bootup, but 10-20 seconds later the PC will randomly just shut down Specs: Intel Pent 4 3.2 256mb 7600gt 1 gig of Corsair P5N-E SLI Motherboard Rosewill 550ww PSU Thanks, MikeNote' that before I fixed the FIRST problem, nothing would display on the monitor, but the computer would continue to RUN without problems. Now that it actually displays something on the screen when it boots up, it shuts down within 10-20 seconds.One more thing, lol, sorry. I've had suspicions, I've been using an old HDD from one of my older PCs.. and honestly, I dont know if it has an OS on it or not... could that be the problem? Though; even if I don't initiate startup, it will still shut down. Sorry for all the posts, Im just really STRESSED Quote from: Eredell on May 05, 2007, 09:01:46 AM One more thing, lol, sorry. Lack of an OS won't cause a sudden shutdown. When I read through this thread, the first thing that catches my eye is the cheap power supply. That could very well be the source of your problems. When a power supply goes down, it often TAKES other components with it. To minimize that risk, use a power supply from a top-tier mfr. such as Seasonic, Enermax, Antec etc. I would try a "known good" power supply and I would also, lacking a bonafide OS, use a Linux *liveCD as a test OS. *liveCD Runs the OS from your optical drive. Burn your own or check with your local computer shop, they will probably give you one.About the power supply I've read reviews of customers running the thing on twice as much as I am, and everything works great. So is it I just got a faulty one perhaps? You cannot rule out the power supply. A faulty PS will exhibit symptoms such as you have. To eliminate that variable, you would have to try a good power supply in place of the Rosewill. Also, the problem could be a faulty component. Here, you could try a minimal component startup. Disconnect everything but keyboard, mouse, monitor, 1 stick of memory. So, all your drives will be DC'ed as well as any PCI cards, USB conns. etc. If the machine starts without the spontaneous shutdown, you know that one of the DC'ed components is at fault. Start adding them back in to isolate it. Of course, shutdown, unplug, observe ESD precautions as you go! If there is no change and you still get the random shutdown, try going even more minimal from th basic group.. Such as try a start without any memory. This will force a beep code from a healthy system telling you that no memory has been detected. You could also try minus video card, mouse, keyboard one at a time, of course. Do not hotplug! Shutdown between trials. If auxiliary power is required for either the mobo or video card is required, make sure that it is properly plugged in.
