PC no power Hi guys, kindly help me on this one please. One of the PC on my computer shop just suddenly stops working.
It is a core2duo in a p5sd2 motherboard.
i dont know what happened but the PC just stops working and wont power up. when i switch the power on the fan will just respond in few seconds then will stop, an indication that the PC did'nt boot up.
I tried to pull out the power supply from other PC and test it on the problematic PC but still its not working. i also replaced the AVR from other PC but to no avail.suggestions would be greatly appreaciated.

Are you assembling/reassembling this machine? The reason I ask is it sounds like too much heat sink paste between the cpu and heat sink, or the fan is not completely secured to the motherboard. But, could be faulty memory or a defective dimm slot too. If all else fails, you could always remove the motherboard and test it one component at a time. Make sure you power down between component installations and use an insulated surface for the mobo.
You didn't supply any info about either power supply so it's difficult to comment about whether the swap should have worked or not. "i also replaced the AVR from other PC but to no avail"
What's an AVR? Voltage Regulator?
I have somehow an idea of building a PC but i just cant figure out this one. I don't think that its the power supply that has a problem because i've benchtest other power supply from one of my working PC but it doesn't solve my problem. also the AVR (automatic voltage regulator) is working as i've benchtest any other AVR to my other PC's. To give you a better picture. when i switch on the power of the PC the fan will just respond for couple of second then it dies afterward. Power supply fan, CPU fan and the case fan will stop. (an indication the there in no power)

i an not assembling/reassembling my machine. it is working before as it is one of the workstations here in our computer shop. and then one day it just won't power up.
