Hey guys!!! I recently bought a new pc and im facing a somewhat peculiar problem... When i turn on the pc, after booting, when the windows 8 logo appears, the Windows loading process is done very quickly (in about 1-2 secs when the normal loading time is about 5-6 secs) and then, just before the "enter password" screen my monitor displays "no signal detected" and my pc restarts. When it does, loading Windows works like a charm... It always happens the first time i turn on the pc.... And again sometimes instead of just restarting my pc freezes on the enter password screen and i cant even hard reset!!! I press the power button for an extended period of time and nothing happens!!! (normally it takes about 2 secs of pressing the power button to shut down) I have to completely shut down the power on my system by turning off the power switch on the psu and that can possibly damage my psu or my entire system. In this occasion also after turning on again my pc everything works fine... My pc is almost brand new (i bought it 3 weeks ago)

Specs:

CPU: AMD FX-6300
GPU: Saphire HD 7870
MoBo: MSI 760GMA-P34 (FX)
RAM: 8 GB Corsair
PSU: 550W power supply
HDD: Toshiba 500GB HDD
OS: Win 8.1

Hi there, im from Greece, and the PSU is from a local PC company called "Turbo-X". I know that this couldn't ring any bells to a non-greek but here it is quite well known. The PSU is this one: http://www.plaisio.gr/ypologistes-anavathmisi/anavathmi... (everything is in greek so you may want to google-translate to figure out what it says). However how can it be the PSU? I mean if you exclude that turning-on restarting and the occasional complete freeze everything works like a charm after a proper windows loading is done. I mean, i've been playing some really demanding games like Crysis 3 on ultra settings or working with "heavy" programms like Autocad for extended periods of time, and never had any issues. All these **** happens when windows logo appears and that loading "thing" starts rotating. So i was thinking of a Windows error of some kind.....

I understand that my PSU isnt top quality, still its value for money as far as im concerned. And i really havent heard of any issues about this brand's PSUs. But even if are right and my PSU is faulty, how can it handle almost a 10 hour straight "stress-test" ( => hardcore gaming ) per day? Remeber that this problem appears only at startup and only once. I have no pc freezes or restarts after i log in my windows profile whatsoever. You exclude the possibility that this is a Windows 8.1 error of some sort?

Also are you saying that my RAM could be faulty??? I really dont think so, since i already told you that i run very RAM demanding games and applications all day long... Never had any RAM shortage issues and the effects that this kind of shortage could cause (abruptly closing applications, pc freezing, shutdowns etc, etc)

I understand tha you' re trying to help but this "some people have errors, some dont" isnt very helpful... It would be very helpful if someone could help me locate the problem in my pc or/and if someone who had the same problem could write here, his approach to the matter. Also, just in case, my drivers are all up-to date...
