I have a DIY computer that was built about 3 months ago, and worked fine until this week where it shut down suddenly while using Word. The only other application running at the time was Google Chrome. Since shutting down it will not reboot. The lights on the motherboard are lit, but when I hit the power button it gives a quick flash of the fan lights, then nothing. No beeps from the motherboard.
Here's what I have: Motherboard = ASUS P8Z77-V CPU = i5-3570K Ivy Bridge 2 x G. Skill Ares Series 4 GB SDRAM Rosewill HIVE-750 W PSU Seagate Barracuda ST1000DM003 1 TB ASUS DVD
Here's what I've tried: - unplug everything, wait and try again - no change - new PSU - no change - Jumper the power contacts on motherboard to see if it's the power button - no change - paperclip test on each PSU to confirm working - both PSU's work - paperclip test plugging in one component at a time - DVD plugged in works - GPU plugged in works - HDD plugged in works - four fans, DVD, GPU and HDD plugged in - works - motherboard plugged in - doesn't work
I've tried it with the motherboard plugged in with only one SDRAM installed, trying each of the two in each of the two slots - no change
I've tried it with the GPU removed - no change I've even tried it with the CPU removed - no change
At this point I'm thinking it's the motherboard. Does anyone have any thoughts about how I determine for sure before buying another unnecessary part to go with my new spare PSU?
