Random problems with booting up and/or loading windows. No issues whatsoever once the system loads.

Hello guys,

That is the first time I am writing to ask you for advice but I honestly don't know what may be causing my problems and how to solve them.

Recently I built a new PC, specs are as follows:
Core i7 4790K,
ASRock Z97 Extreme 4 motherboard,
2x 4GB of G.Skill Ripjaws,
a 650W BeQuiet DarkPower Pro PSU,
GeForce GTX770,
a 120 GB OCZ Vertex 4 SSD
and a 250GB WD HDD

and instantly my problems started. At first the system had problems with posting and the mobo error display indicated that they were caused by my SATA drives. The system would get stuck at the manufacturer logo and would not post at all. After rebooting it would boot up with no problems. I found some suggestions that it may be solved by restricting the Legacy USB support to windows only. It worked. For a while.

A while later (like two weeks) my system started taking a lot of time to switch off and after another day or two the windows was not able to start at all. Reinstalling or as I discovered later on, restoring the system from the last restore point was able to solve the issue. Now it turns out that usuallly unplugging SATA cables from my hard drives and optical drive and plugging them again is enough to get the system running. And it used to happen every couple days or so.

Today, after the system was not starting properly yet again I shut it down, did the usual reconnecting of SATA cables and tried to start it again but it would not start at all. Pressing power button didn't do anything. I kind of blamed mobo, so I thought that the damn thing finally broke down entirely. Still after like 10 minutes I tried again and the PC is running as if nothing happened. And once it starts running I can game on it for hours straight with no issues whatsoever.

While trying to figure out what is going on I shuffled with couple HDDs and it seems my drives are ok. For the rest of the parts I don't have replacements and I am not able to test them in another system. Temperature wise everything seems to be ok according to my mobo diagnostic app. The CPU could be a bit cooler but I am using the reference cooling for now so its 65-70 celcius while gaming is acceptable or so I heard.

Summing up, does anyone have any idea as to what may be causing it? What should I RMA?

I would be grateful for any hints, thanks

J

Thank you for your suggestion Kapitalistas.

I did as suggested and confirmed that the mobo is properly attached to the case and reconnected all the cables. As a result the PC started properly and it was working with no issues for two days. On the third day it hanged while I was trying to switch it off. Funny thing after I manually forced it off and turned it on again Windows loaded as if nothing happened. No message indicating it hasn't been switched off properly previous time.

Any other suggestions? What do you guys think is responsible? I am thinking of RMAing the mobo but am not sure if that is the real problem here.

Thanks a lot in advance for any hints and suggestions.

Sorry for the delay. I simply don't have that much time to tinker with my PC.

Well, anyhow, I tried what you suggested and booted couple times into a safe mode. PC booted and loaded system without a problem. Once it took like 3-4 seconds longer, but on average it was 24 seconds.
Still, the first time I tried to load windows normally after using the safe mode system froze on windows splash screen and I needed to restart. Following 4 or 5 times it worked ok averaging 34 seconds. I also tried booting up with the fast boot option, but it gave me only like 1-2 seconds faster boot time and during 4 attempts the system crushed once.
