my delid i7 4790k stopped working after 1 year . do i need to re-do the thermal paste on my delidid i7 4790k ? please help

post #1 of 3
Thread Starter 
last month when I booted up my computer and nothing posted on screen . I thought it was my motherboard, i changed my motherboard and it fixed the problem, then 1 week later the computer would not boot up again, i then brought my computer to a pc repair shop and had them change the motherboard and they discovered when my cpu heatsink water block is screwed on the computer does not boot up and when i my cpu heatsink is not connected it boots up. the pc repair guy said that when there is pressure on the cpu from the heatsink the computer will not boot up. the way i delidid my i7 4790k was with the razor method and i used cool laboratory liquid pro i then glued the lid back on the chip. will redoing the thermal paste on my i7 4790k fix the problem ?

I delidded my 4770k over two years ago using the two block method, used CLU, overclocked it to 4.5GHz and it is still going strong.

Seems obvious that something is going on between the heatsink and the CPU itself.

That would be the first thing I'd do is to remove the heatsink and inspect what the thermal paste - CLU is doing (leaching/dissipated). Clean up the area and reapply carefully.

What glue did you use? Did you coat the resistors with clear nail polish? Did you use a lot of CLU?

CLU highly conductive so if any got on the resistors, it may have shorted something.
