Computer not turn on

So its either one of two things here.

1- somehow a step was skipped and/or something is just not seated right. My guess would be that its the processor itself (due to the lack of error beeps). You see if the processor was seated correctly and the computer turned on then the PC's BIOS would give you error beeps telling you that somethings amiss.

2- something is damaged and needs replacing. I have assembled hundreds of pc's and i can say with confidence that 99% of the time when the newly created pc does not want to cooperate its because i missed a step or didn't seat/connect something properly.
However there is that 1% that does not turn on due to bad hardware.

I would remove the RAM, the heat sink and any cards that are in the pc and make sure to take my time putting them back in.

If that does not work i would start replacing parts starting with the RAM (#1 thing to fail in my experience they are so fragile sometimes) leaving out the PCI/PCI express cards, and ending with the Processor. try to get a bare bones PC working then work your way up.


I hope this helps and im here for ya

have you try to remove the heatsink fan? if not remove the heat sinkfan and reseat the cpu, also make sure that the power supply you bought is equal or greater of Watts as the old one. Also make sure that you connected all the wires from the power supply to the motherboard and remove your memory ram and put it back in. Let me know how it goes.

Since you replaced the PSU, I would take all the adapter boards out IE:Video,NIC card, Modem etc.
Then I would take out and reseat the memory. If you have more then one stick of memory, re-install one stick and then power the unit up. If it powers up add the other stick of memory, again see if it powers up. depending on whether it power up , you will know whether the memory is the problem.
If it powers up with the memory installed, then install one card/adapter at a time to see if one of them is causing the problem.
If after following these steps, it still does not power up, then you probably have a bad motherboard or Processor.
Let me know what results.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

open your pc then turnit on and tell me if the master fan is workin,
trying changin RAM too bcoz when the ram is demaged pc cant start
if you have a volt tester u cant test if ur motherboard is getting power or not, if yes It can be possible to repair
if not that mean one of the lil components has burned out
