Thanks for the reply! Yeah, I had the exact same thought - and even wishlisted a few PSU's on Amazon the last time this problem happened.but I'm not too knowledgeable, so I didn't want to just upgrade without getting a more educated opinion. If this surge of current causes the voltage to drop too low.your PC can crash. Surges of current generally cause PSU voltages to drop. When your PC wakes from sleep it draws a surge of current from the PSU. I'm leaning on that it's the PSU and here's why I lean this way. I don't have much knowledge.would this problem be a power issue? Is my PSU going bad? Is the motherboard going bad? Is there any way I can diagnose the problem without just actually replacing parts? I'm guessing the problem is hardware related. It had been several weeks without a problem until it suddenly crashed on me tonight again, and the symptoms are always exactly the same. It might goes for many days without any problems.and then suddenly it starts up again. It doesn't happen all the time, I've wondered if it wasn't getting enough juice and I opened it up to make sure all the cables were connected properly and usually that "fixes" it (I say that, but I have no idea if it actually fixes it or if it's just coincidence.and I'm slightly suspicious that it is has no effect really). When I try to wake it up from sleep (either by mouse or keyboard), the computer tries to wake but then instantly goes completely silent (shuts down).then it tries to start up again by itself after a brief pause, then almost immediately goes dead again.then repeats, and then finally on the third try it is able to reboot and it starts up the computer as if it had been restarted. Hi, I've recently started encountering this problem on my desktop.
