only today ive noticed my PC has been restarting randomly without any bluescreen and i dont know why. I've seen people say its a PSU problem but its never really happened before while i've had this PSU so i dont think it is. I also thought it was because of playing Battlefield 4 as it only happened at first while i was playing that but about 10 mins ago it did it while i wasnt on a game so im not sure what it couldv'e been?
PC random restart without BSOD?

Greetings,
What brand/model PSU do You have? What VGA do You have? When You encounter the restart, are the VGA fans spinning?

Erm, by any chance, can You run FurMark/MSi Combustor, and "heat up" Your VGA to maximum, for 5-10 minutes?
Also, what was Your ex-PSU that You changed?

I asked for PSU, because it may have damaged motherboard, e.g. part that takes care of PCi-e ports [which should be CPU, but there are still residuals of chipset even nowadays on motherboard].
The test is gonna tell You whether it's something with VGA. If it's VGA don't panic, just try different 12V PCi-e ril, 7xx PSU should have at least 3.
If it's gonna get repeated in the test on each rail, You'll have to RMA Your graphics card [VGA].

OKay, first things first. What model of GTX 770 do You have? Most of them eat 2 x 6pin, or 1 x 6 pin & 1 x 8 ping, which is "not good for business".
And 12V PCi-e rails are those, which are connected to Your VGA [graphics card].

OKay, in that case You can probably only change one rail. Please make sure the rails are connected firmly and they "click" to Your VGA. And if You have 3 12V PCi-e rails on Your PSU, please change at least one, than try the other one. After each exchange, run FurMark.
weirdly this PSu only has 2 6 pin connectors hence i was using a 2 6 pin to 8 pin adapter and fot the other 6 pin it was using a 2 molex to 1 6 pin adapter also. anyhow ive changed some of the connectors around all all seems good actually. Furmark is running as we speak and no crashes have happened as of yet (touch wood). Also when i pushed the connectors back into the sockets there was a louder click from the GPU as if it was clicking into the PCIe slot so i think maybe that couldv'e contributed too if indeed that was what it was

Run it for a few more mins, and You should be good to go. Incorrectly inserted rails into VGA or into PSU [when it's modular] can result in crashes, since it doesn't give sufficent power to Your component.

It should, actually "good burn test" lasts 24-48 hours, but if You won't experience any other crashes, You're good. I'd do 10-15 mins just to be sure.
ok will do. ill let it run for a bit then. thinking about it now i did remove my CPU fan recently to 'de dust' it and i could've knocked one of the power connectors or something cos i did have a move around with some of the wires. Anyway thanks for your help your a life saver lol

Glad I could help 
PCi-e slot is extremely sensitive to be "clicked" right, even different angle of vga in PCi-e screw-wise can cause such a trouble. And also badly connected power supply unit cables.
I'm just glad it's not the vga [gpu or vram, or something], that's wrong.

yeah at least it was only a power connector issue and not something worse and more complicated lol. tbh i would eventually like to upgrade to a Corsair Modular PSU when i can afford it. hate having all these cables lol xD

Yup, modular are great. I personally love RM, but people here hate it, so if Corsair, go HX, or AX, it's a sure strike. Or some other brand. I personally have absolutely no trouble whatsoever with RM, but I guess global experience is different.
