2 weeks ago I assembled and build my second gaming pc and everything was running smoothly.(didn't do any overclocking). Here's what happened: I installed Assassins Creed Unity on the pc and everything was going fine the first 3 times I ran that game. But the fourth time I started seeing that my fps(using fraps) lowered to 20 fps which meant that there was something going wrong...
I started messing with the graphics settings inside the game and all the sudden the screen went black for a second and then i saw red,yellow and blue boxes(I thought the gpu had failed or something) and all the sudden BAM... pc crashed. Tried to turn it back on but even that didn't happen even after waiting some time. The only thing I could hear when trying to power on my pc is a little movement in the fans and a small beep but that's it: no any signs of life. So I thought I was well damned and I started removing stuff to determine what seemed to made the problem.
Here is what I did: removed the gpu, removed all the sata, case controllers till I remained with only 1 RAM memory dimm, the cpu with its liquid cooler(seidon 120v), some case fans and thats it. What happened? No luck. Then I decided to clear the cmos by removing the battery. After doing that my PC finally booted up and I got into the bios. Restarted my PC to doublecheck and then got chassis intrude detection thing. That problem I got fast solved by again clearing the cmos while the jumper of the chasis intrusion was on the right setting.
, finally connected back my sata devices and the all the rest EXCEPT THE GPU. And everything ran as itshould. Next thing I read on a forum is that your gpu should always have 2 different power 8- pin cables and not the same. I had one cable which ended into 2 x 8-pin gpu power cables. So what i did is take a seperate capble so that i would be sure. Well guess what happend after i plugged those 2 cables? I saw a green light on the mobo, and 2 green lights on the gpu... so I thought to myself maybe its going to solve itself. BAM... there it was... my pc not starting up and showing no sign of life just like after the pc crash.
I was wondering if anyone could help me or suggest what can be the fault here?
My specs are:
CPU: Intel i7- 4790K Stock Freq.
CPU cooler Seidon 120V with stock CM fan on radiator
M.emory: 2 x 4 GB Corsair Vengeance Black
HDD: 1 TB WD Blue
DVD: Cheap budget asus dvd player
Mobo: Asus Z97-K
PSU: Corsair Modular RM 750
GPU: Asus Gtx 780 Ti 3GB(the name of the gpu on the box is slighlty longer)
Case: Corsair 300R Carbide Windowed
Any suggestions are helpful!
