Your next step is reseat the components inside the case. memory and video card especially. If you have a known good power supply, try that next. Check your power button, both switch and cable.

Green light behind motherboard blinking when power is connected


That is an indication that there is power to the motherboard. It normal but does not mean all is well with the PC. If your PC works fine, then there is nothing to worry.

Compaq Presario SR2150NX doesn't turn on. Front panel green light turns on but nothing else happens (no fans, no boot, no noise, nothing) Please advice


On the back of the Power Supply there should be a Green LED, When you power it on if it is flashing, this means that the Power Supply is dead and you need to replace it.

My HP a420n won't start after replacing cd-rw drive


Please try to remove all the connections from your computer and also connections inside the motherboard, the power cord for your hard drives and also the power cord from the power supply to your motherboard.After that, remove the memory and clean the pin by using an eraser of the pencil. And then insert again the memory stick and connect all the connections from the power supply to motherboard and everything. Lastly reset your bios and put it back to normal again. Hope this would help. Thanks..

I have a blinking green light on the back of the PC by the fan. What does that mean


That all depends.
Some computers have a small cluster of 4 leds that are used for diagnostics or if you have your computer on a network (cat 5 ethernet cable) plugged in then all it means is that there is activity on the network.
