Hi guys, I will try to describe my problem as good as i can.
Sorry this gonna be long post and i hope it will not frighten you :)

My PC was functioning fine for about 4-5 months and one day when i wanted to turn PC on it failed to do it correctly: at first it restarted shortly after i started using PC, after that it never booted windows, PC starts to boot(maybe it will even show something on desktop but after few seconds it goes restarting again) so i had to shut it down manually (pressing Shut down button for 10 seconds). I removed PC from power conector and after some time tried to boot it again and it did the same. I tried to solve the problem: last time i was using PC i have instadll some softwares and i thought that may has changed something in windows and therefore installed new copy of windows. But the problem stayed and it seemd to go worse(did not boot t all and restarted itself as few second later form turning on PC). I send PC back to the shop, where i have bought it, they powered it and it did not showed any problems(!) : powered on correctly and behaved as it should, But still i asked them to check it more detauly. after few days they sad that they have checked every detail and they where functioning fine. They install a clean versen of windows(not genuine).

Everything seemed okey, after some time i installed softwares i needed. Next day it started the same problem. Well i thought that it was software who caused the problem(Zbrush 4R5 by the way). I managed to install clean version of windows myself (and formated both drivers so no data was stored on them).

Life seemed beautiful until this Saturday: my mysterious problem has returned and it can't be software i hadn't made any new installations for a long time(nore updates). From last intallment of windows i used two HDDs(i had installed WIN on both of them).

Now: 1)if i uninstall any of HDD's the problem stays, i even removed both of them it stayed!
2) removed the GPU not any good news

Last time before restarting blue screen appiered it said something about USBPORT.SYS

I see many people had same problem as me here, i have red some of the forum articles but none seems helpful for me.

I dont know what to do as Shop says the hardware parts are ok. I can still return PC to them to check but for now i dont see a point, but if i'm unable to solve it here i will probably do so

PC specs:

CPU i5-2500K
MB ZH77A-G43
RAM G.Skill 4GB Ripjaws 1600Mhz (x2)
PSU OSZ 750 W fatal1ty champ1on
HDD Seagate Barracuda 1TB 7200.14 6 GB/s (main)
HDD 2: Barracuda 7200.10 3GB/s
GPU MSI GeForce GTX 560 Ti

Note: when i bought PC the shop has got wrong RAM's for me uncompatible to MB(therefor i have little thrust to them. Heat is not a case here its okey. Blue screen has rarely appeared And i'm not using any anti virus, just made scan after reinstalling WIN, was using registry mechanics.

PS. I hope i'm in the right directory and sorry for my English)

remove everything from the case and "breadboard" the motherboard - start from scratch basically, motherboard on a flat surface (not carpet) and connect the monitor with on-board video, no cards in the motherboard, only one stick of RAM and no drives - see if you can enter BIOS

one more thing: my MSI MB shows basic specs of my PC, temperature- it is ok, CPU model and RAMs installed, thing is that it shows current DRAM frequency 1333Mhz, but RAM support 1600Mhz, is this some kind of problem/can it cause any problem or should i just change that later on to 1600?

so the cause of these issues is because you set an overclock that the system didn't like... is that correct? you didn't mention anything in your long original post about overclocking...

I would reset everything to stock, however the mb sees it - it's possible the shop had no issues because they remove the overclock of the ram and then put it back telling you everything was ok... devious, but you never know... i don't see how they can build the system with incompatible ram in the first place :\

Some News: after my last comment i have decided to connect HDD and see if it would work correctly and it did fine. i decided to go further and connected the second RAM and system started to rebooting after i turnd it on. So i think RAMs are causing the system not to work correctly. any explenetions why? "Note: when i bought PC the shop has got wrong RAM's for me uncompatible to MB(therefor i have little thrust to them.")- and they changed it, but seems they dont know how to choose correct RAMs

I Bought this PC because its strong now and in the future if i needed some more "power" i could have OCed it. but for now i have not OCed it because basic settings are fine for me and i have no experience in OC.

To understand my situation: i live in Georgia(country) the shop basically sells desktop computers and separate PC parts as well, so i choose the specs CPU, PSU,GPU, MB and also i said i wanted 8 GB with 1600 Mhz of ram and they sad "THIS" would do fine to my system. They where wrong, firs they said they got wrong letter at the end of RAMs name. Now i have this G.Skill 4GB... 12800CL9D previously i had the same but letter D at the and was different. So i'm going to have my RAMs replaced but sadly i cant know if the new ones would be compatible to other parts....

And Thanks for your Help!
