Have a client's computer that is completely dead after a local thunderstorm. Swapped PSUs and system will still not start. There are no burn marks or signs of damage inside the computer. Took the motherboard battery out for a couple minutes, no luck. Hard drive reads fine in external enclosure. Gonna try some different RAM, any other ideas?
 
The only thing left for you to do is a processor swap (assuming that you have a spare handy).
 
the motherboard should do something (beep, LED flash etc) whether or not stuff is plugged in (cpu. ram, gpu etc). if there is no sign of life either it a BIOS beep code, LED/LCD flash or error code, the MB is probably buggered.
 
motherboard light comes on when PSU is turned on, but computer will still not start
even tried jumpering the pins to start it incase the front switch was bad

tried new RAM, nothing
took the CPU out and it looks fine, no burn marks
 
is the psu confirmed to work?
i had similar issue with my mb. the mb LED lights came on and the fans started spinning but that was it. swapped out psu and system booted.

also have you tried a confirmed working display adaptor.

swapped the stock dell one with a brand new Corsair CX430
what do you mean by display adapter? the monitor definitely works, but the system is completely dead other than the motherboard light being on, not even the PSU fan spins up

even tho it's new (this scenario is highly un-likely), doesn't necessarily mean the psu is in working order.

i was referring to the graphics card.
have come across mb's before that won't POST or provide an error code if the video card is 'faulty' or missing the pcie power connectors.
 
no power = mobo or PSU, all other items being faulty still cause the mobo/PSU to power on first.

yeah I'll check the PSUs with a PSU tester
videocard is integrated into the motherboard

looks like new computer time
