Hello and thank you for helping me. Over the weekend I cleaned my computer by taking out the video card and the cpu and cleaning everything with dustoff. When I put it back together the computer would not turn on. There is no response from any drives or fans. On the back of the power supply unit, near where the power cord plugs in, there is green light. While plugged in this green light is usually solid. Now, when the motherboard is connected to the PSU, the light will blink rapidly. When I disconnect the motherboard from the PSU the light on the back of the PSU will once again become solid. I have tried disconnecting everything possible to eliminate any other faulty parts with no response from the computer. I have looked in the PSU and around the motherboard for burns or other indications of something faulty but haven't seen anything. Do you have any recommendations for how to tell which part, if either, is in need of repair or replacement? Thank you very much! Some info: I have a Sony Viao VGC-RB52 with an Intel Deskboard D945PPR My power supply is stock with a max voltage of 300w (which has been fine, I haven't changed any parts lately)
What tool did you use to clean the inside of your PC? Using a dust brush like this might create static and damage parts. What i would check is your PSU's manual and see if there are any indications as to what a solid green light and a blinking green light, mean.
