PC, won't boot, restarts once, no display or beep or even power button led.

It all started yesterday. I was cleaning dust of cpu fan. I took the heatsink too, after that I putted all
in place and turned on.

The power button led was not working but all fans work and no display. It keeps going for a few seconds and then stops after that it runs again and no display nor the power button led and it keeps working like that.

I tried putting another PSU, same thing happend. Also tried BIOS reset, CMOS battery removing, tried with no ram or just one - no beeps.
Somehow this looks strange:http://i.imgur.com/i1JyKPQ.jpg

My current build:
Mobo: Pegatron IPIEL-LA3
CPU: Intel Pentium Dual Core 2.80 Ghz
RAM: DDRD3 Samsung 2x2GB 1333 Mhz
GPU: ASUS Geforce GTX 750TI OC
PSU: MODECOM 450W

Would anyone happen to have a solution to this issue? I attempted to search for an answer on the forum, but couldn't seem to locate anything enough to this issue. I think it is Mobo but I'm not sure.

  1. Did you put new thermal paste on the cpu before re-installing the cpu heatsink?

    Did you reconnect the cpu heatsink fan?

    Is the CPU fan spinning, if its not the make sure that its plugged into the correct fan header on the motherboard. Also make sure that you applied thermal paste on aswell

    I did put thermal paste on cpu after I cleaned the old one. I reconnected the heatsink as it shout be. I did not seperate heatsink and fan.

    It is spining I added thermal paste on CPU after cleaned the old one.

    Yes
  7. Remove and refit the heatsink again.

    Remove the heatsink and clean the old thermal paste off it and the cpu with isopropyl alcohol.

    Then put a pea size drop of Arctic Silver 5 on the cpu and remount the heatsink base.

    Plug your cpu cooler fan back into the motherboard cpu fan header. Test,

    What else I can use to take off the old thermal paste?

    Try ArtiClean with a lint free cloth. You could also use rubbing Alcohol.
  10. You don't have access to Isopropyl rubbing alcohol? It's pretty common. You can buy that in any convenience store or pharmacy. I recommend at least 90% Isopropyl alcohol. Also make sure you use lint-free cloth like coffee filters if you don't have something better.

    When cleaning, make sure you hold the CPU on its side. Don't touch the bottom pins or you can damage them. If you damage them, there's no fixing it. Wet the cloth with isopropyl alcohol, but do not drench the cloth. Apply a little bit of pressure when cleaning the CPU. Make sure it's all clean. Do the same for the heatsink. You don't have to be as careful with the heatsink as you were with the CPU. Let them sit for a few minutes to dry out. Put the CPU back onto the motherboard. Then re-apply a small amount of thermal paste on the CPU (a pea-size amount in the middle will be fine) and re-install the heatsink over it. Do not apply too much thermal paste as that will also be a problem.

    If you really do not have access to isopropyl alcohol, you can buy a cleaning kit. It's more expensive.
  11. From the picture you linked "Somehow this looks strange:http://i.imgur.com/i1JyKPQ.jpg", it looks like you bent alot of pins which results in the CPU not fitting right.

    I do not have these things, maybe there is a simple way?

    How can you tell? That's the motherboard CPU slot. There are no pins.

    It was working fine till I changed the thermal paste. (It was yesterday)
  15. Did you remove the cpu to fit the heatsink?

    I do not know if it is the main problem, if it is I probably will need a new Mobo.

    What do you mean?
  18. Did you ever remove the cpu?

    Yes. http://i.imgur.com/huM4xsC.png
  20. Near the time that you put on the new heatsink?
  21. i7Baby said:

    On heatsink nothing. As you asked me if I putted thermal paste in start of this thread I just only added to cpu.
  22. This is getting confusing.

    @TheJitsu - I suggest you give it one more try from scratch again. Just follow my post here to re-clean and re-install the CPU and heatsink.

    I will try :)
  24. I suspect he has removed the cpu then bent pins refitting it.
  25. i7Baby said:

    Easier way would have been to ask for a picture of the bottom of the CPU chip. Then you can verify it yourself. The round-about way of asking is a tad confusing at what the point was.

    If the pins were bent, the CPU wouldn't fit.

    That means Mobo is critical damaged?

    The CPU fits perfectly in it's slot.
  28. TheJitsu said:

    No; the CPU. There are no pins on the motherboard (in relation to this problem). Just to clear the confusion, can you take a picture of the pins on the bottom of the CPU?
  29. Also make sure you don't get thermal paste on the motherboard cpu slot.

    You mean this: http://i.imgur.com/Zv9UJTm.jpg ?
  31. Looks good to me. I didn't think the pins were bent anyway because you wouldn't be able to fit it into the motherboard. But @i7Baby was really concerned about it. :P

    Again, just follow my post on re-applying the thermal paste and try again.
