I have recently replaced power supply and overhauled my computer. Now I find it will not boot. Have tried the usual removing of RAM etc but still no effect. Drives are recognised, CPU fan is operative but there is no action from the monitor (The monitor is sound - works as extention for laptop!)
Anyone got any ideas what to try next?
I fear the mainboard may have gone aswell as the power supply, but seems too coincidental they both go at the same time!
OH yes one other thing, switch doesn't work to isolate power to computer on the front panel!!!
In anticipation, thanks, Gary

he can get into the BIOS, particularly as he has no display on his monitor?

Disconnect all of the drives.

All you need to start is the motherboard with a CPU+fan, memory (install one piece of memory only) and a video card if the motherboard does not have onboard video.

If the motherboard has onboard video try different slots as the onboard video usually only shares memory with the first slot. Disconnect the power before you change memory slots.

Plug in the power supply and see if it boots.
