So my dear friend was supposed to change my CPU while I'm away. Apparently, he wanted to test the PC without putting back the heat sink. The terrible thing is, he did it with both CPUs :_(
He says the computer very quickly shut itself, so he's "sure" that the CPUs are fine. However, I tried booting the PC with both CPUs (with heat sink fixed and thermal paste applied); I get a black screen in both cases.
Unfortunately, I don't have any extra parts to test or extra PCs to test these parts. Is there any way for me to determine which parts are working and which are not? Unfortunately, I don't have spare parts to do A/B testing or an extra PC to test my current parts.
When the PC is turned off but plugged into the Power Source, the LEDs of my MOBO and the GPUs are working. When the PC is turned on, both my main cooler fan and the fans of the GPUs start working. Also, I suppose the heat sink is working as the thermal paste was spread evenly across the CPU surface. Hence, I assume the MOBO is fine as well. Am I correct in my assumptions?
In case it helps, here's my setup:
- ASUS Z170 Pro Gaming MOBO
- Intel i7-7700K and i5 6400
- 2 * GTX 970 ASUS Turbo(aka SLI)
- 32GB (4*8GB) DDR4-2800 ADATA XPG
- 700W Standard 80 PLUS Bronze
