HP Recommended
Product: Hp elitedesk 800 G1
Operating System: Microsoft Windows 10 (32-bit)

Hi there, I have an HP Elitedesk 800 G1 desktop computer which was working perfectly as of last night. After shutting down I switched it off at the mains. This morning it won't power on. The white light on the front is on constantly and the green light on the motherboard is also on but no joy on actually switching it on.

 

- I have tried a hard reset by unplugging, holding down power on for 15 seconds then plugging back in

- reset cmos button

- taken out power supply to inspect but there are no buttons to push on this so can't see how to reset psu

 

When I take off the kettle lead then plug back in the power briefly comes on, power button goes green for a few seconds and the fan starts then all goes dead except for the white light next to the power button which is on constantly.

 

Any ideas what the problem might be?
