Was exporting a video in premiere and then my hp envy 750 desktop computer flashed a quick blue screen and now won't start at all. The green light is on and solid in the back by psu, but power switch won't do anything... I tried a hard reset and all other ways to start it that I found online to no avail...
Is it worth replacing the PSU if the green light is on?
I can't find your product using Envy 750se. I guess you are out of warranty.
It could be the power supply, or the switch, or some other component.
Examine the motherboard and PCIE add in boards for damage (thermal or bulging/leaky capacitors.
Try a minimum config: disconnect all SATA devices, USB devices (including front panel stuff), remove the RAM, remove any PCIe add in devices if applicable. Reseat motherboard power supply connections.You could try starting the PC using a screwdriver to short the power switch header pins on the motherboard to check the power switch.
See if you can get an on screen POST error message about the RAM or no boot device found. Then add each component back if you get a successful POST error message. You have found the bad component when the problem recurs.
The problem here is you may need to try different known good components such as the power supply. This can be costly
You work your way down to the motherboard to find the failing component.
