Bootloop, PSU seem to be good.

[sdrako]

Hi, I reently posted a few problems with my pc, I though it was the psu but a friend give me a tester and show that it is good. I try with one new stick of ram and the problem persist.

The problem is when I turn it on don`t post. If I have enable the dual bios it restart until can boot. In single bios have to hard reset until boot. This happen a few months ago, with another mobo. I change it and with the new one it's the same. Yesterday bougth a single stick of new ram (Kingstone 4 GB 1333) to discard if any of my sticks were bad, but the same.

I don`t know what it can be. New mobo, ram, tested the psu and pass. Need help

I leave you photos of the tester and a video of the problem.

Did it ever boot up? 

 

Does it ever boot up?

 

You may have a dead CPU or it needs to be re-seated.

 

But before you do that make sure you troubleshoot by removing all un-needed Peripherals, (i.e. Sound-card, wireless, GPU(Only if the motherboard has on-board graphics) ) 

 

Re-seat RAM one stick at a time and the Graphics card.

 

Ensure all system cables are completely inserted correctly.

 

Usually in a situation like this it is not the PSU (and since you used a tester i think we can rule that out entirely)

 

What are the machine specs?

This build worked solid about one year. About two months ago appear this problem. I trougth it was only the mobo, but with the new mobo the problem persist.

I tested only the mobo + cpu + ram.

Tested the two sticks and the 4 sockets for ram. Buy a new stick of ram, same results.

Reseat ram, cpu, cooler. Change the cables of cpu, gpu, sata etc.

 

When it can boot I can enter te bios/uefi. The temps of the cpu are good (34º C) and I leave it long time (about 2 hours) and everthing works fine. The same with the ram, recognize it.

Cant boot the windows installation, it`s freeze at the logo, the same with any live linux distro. I tried others usb ports (2.0 and 3.0) and other usb sticks and diferents isos.

 

The only thing that make sense is a bad psu, but the tester say its good.

Do you have the ability to try a different CPU? Otherwise I am afraid I am out of ideas. Good luck.

[sdrako]

No, but I have a friend who works at a pc workshop, he will help to diagnose the pc.

Thanks

Just curious, did you happen to overclock the system? This usually happens when you have a bad overclock.

Not at this mobo, with the old one yes it was OC to 4.5 Ghz and work good one year. And my friend test the mobo with a i3 and works, tried my i5 with another mobo and freeze when it load the graphical driver. He is doing more test to see what is happening. But it seem that I have to buy a new CPU.

Sorry to revive this thread, but it was the cpu. It's dead, don't know how or when but it's damaged. My friend (who work at a pc workshop and have more exprience at hardware) fix the firts mobo too. So all I need is a new i5 4690k.

 

Thanks for the help guys.
