Hey everyone. My computer has been acting funny lately. Whenever I am playing a graphically intense (or non optimized for pc) game or doing something else fairly laborious for the computer my screen will crash to black and display 'no signal'. I initially thought it was just my graphics card, so I uninstalled the drivers and reinstalled a fresh download to ensure they were the newest. This seemed to help a bit, but the problem persists. Whats strange is that the problem is not limited to games. If, for example, I preform a disk check on my second hard drive, the same thing happens, black screen "no signal". I am afraid it may be my graphics card shorting out, but my motherboard is still stock as well as the CPU. I really am not sure where to start here. Im sure I need to replace something but just trying to triage what. Lastly, could heat and airflow limitations cause a similar problem?
