Quick lag with freeze afterwards and BSOD sometimes

[Gedaz18]

I am having a real problem lately. At first it started when my computer screen turned off after the specified time and when I moved the mouse or pressed any buttons it did not respond. Then I turned off the feature of monitor turning off, but now I just watch some movie or do anything else or not even doing anything just stuff turned on and huge lag comes and it freezes completely, sometimes the screen goes black or BSOD occurs. I am running Windows 7 64bit. I have done hard drive checks for errors, de-fragmentation with commercial software, also ran memtest64 to check RAM.

It could be a bunch of things, start by stress testing the system to be sure the hard ware is not the problem. Use Memtest86+ to test the ram, Use Prime95 and Intel Burn Test to test the CPU, OCCT with error detect set to ON to test the GPU ONLY (other than GPU testing this program is very unreliable), Use HDDscan 3.3 to check the smart system of the HDD for errors. IF all pass then it will either be a PSU or software issue causing this.
