I recently fixed crashes I was getting in gta 5 by underclocking my evga gtx 750ti by -300 for the core clock and -300 for the memory clock. I tested it for around 1.5 hours and no crashing occured. My power supply is a stock 300w fsp power supply that came with the psu. A possibility is that my power supply can't handle my gpu at full power and causes the display to crash which gives me a black screen or a ctd. Can someone help me by telling me if this is my graphics card or my power supply. My system is an i5-4460, a gtx 750ti, 8gb of ram and a 1tb hdd.
