So I've been working on my cousins computer for a while and I can't figure out what the issue is. I'll run through everything that was happening, and everything I've done so far.
He said his computer one day just went into sleep mode and wouldn't wake up. It eventually got to the point where it wouldnt even power on. He bought a new PSU and that's where I got the system.
With the old PSU, pressing the power button did absolutely nothing. After I put in the new PSU, the machine was getting power; LEDs and fans turned on fine. But after about 15 seconds, the PSU fan would slow down and stop, still powering the system, and would not boot or display to anything. I tried each ram stick individually with no results. I bought an onboard speaker and hooked it up, but was not getting any beeps when there was no RAM. I deduced from that that it was likely the Mobo.
He got a slight mobo upgrade, and i went to breadboard the system. With only the cpu in and the board powered, I now got beeps for no ram. When i plug the RAM in, I get no beeps, but the system still does the same stuff: Powers LEDs and fans, then after about 15 seconds, the PSU fan slows to a halt. I left it on for a minute to see if it would boot to no avail. However, I did notice after this run time that the CPU was getting warmer, so it is getting power.
I've tried connecting the displays to two different GPUs and the onboard GPU. I've tried resetting the CMOS (and even replacing the CMOS in the old MoBo). Ive also went down the checklist on the "No POST" thread.
Specs:
MoBo- Asus TUF z390-plus gaming (wifi)
CPU - Intel i5-8400
PSU- Corsair RM 750x
GPU- Geforce GTX 1060 3G
RAM- 4x OLOy 8G 3000mhz (MD4U083016BJDA)
Any help or suggestions would be much appreciated. Also, do you guys think it was sound advice to get the new MoBo considering what I told you about the old one?
