Hello JaidynM

Sorry for my late reply. I finally got a new graphics card, a 6870, and I thought my problems were gone. But now, it's happening again. My monitor enters idle mode, and nothing is on the display. Later, when I turned the computer on again, i opened a few windows and everything froze. Is there anything I can do to fix all this?

Do some more hardware checking.
  • If you are overclocking any hardware, please stop.

  • Monitor temperatures during the following tests.
    Use the following programs to monitor the temperatures.
  • Run the boot version of Memtest86+ paying close attention to Parts 2 and 3 of the tutorial. Also, in case Memtest86+ misses anything and comes up with no errors, run the extended version of the Windows Memory Diagnostics Tool for at least five passes. These you may want to run overnight since they take a long time to complete (run them an hour before bed each of the next two nights and check before going to sleep that they are still running).

    If you swap any memory components, follow these steps for ESD safety:
    1. Shut down and turn off your computer.
    2. Unplug all power supplies to the computer (AC Power then battery for laptops, AC power for desktops)
    3. Hold down the power button for 30 seconds to close the circuit and ensure all power drains from components.
    4. Make sure you are grounded by using proper grounding techniques, i.e. work on an anti-static workbench, anti-static desk, or an anti-static pad. Hold something metallic while touching it to the anti-static surface, or use an anti-static wristband to attach to the anti-static material while working.
    Once these steps have been followed, it is safe to remove and replace components within your computer.

Sorry for not replying, I must have missed your last post somehow.

Follow writhzidens excellent advice and see if you can diagnose any specific components.

Thank you! I shall follow these steps to the best of my ability, and report back!

I've been monitoring temperatures with speccy (which is AWESOME by the way) and everything but the graphics card is usually under 30 C. Something crazy just happened though: I was on mozilla firefox when the screen turned white and was covered with vertical black lines, with maybe half a cm in between them. Not sure what happened there, because all of last week, I was able to play my games just fine. Is that a graphics card issue or something else?

Those sound like artifacts that can occur due to a badly seated graphics card, a graphics card with dust on it, a bad graphics card driver, or a bad graphics card. Start by checking for dust and that the card is seated properly. To remove dust, use a can of compressed air and never use a vacuum on the inside of the case as vacuums cause electrostatic discharges to ruin electronic components. For re-seating the graphics card, follow these steps for ESD safety:
  1. Shut down and turn off your computer.
  2. Unplug all power supplies to the computer (AC Power then battery for laptops, AC power for desktops)
  3. Hold down the power button for 30 seconds to close the circuit and ensure all power drains from components.
  4. Make sure you are grounded by using proper grounding techniques, i.e. work on an anti-static workbench, anti-static desk, or an anti-static pad. Hold something metallic while touching it to the anti-static surface, or use an anti-static wristband to attach to the anti-static material while working.
Once these steps have been followed, it is safe to remove and replace components within your computer.

Follow the above steps to the best of your ability. You should also follow the ESD safety steps when blowing the dust out to be on the cautious side. For blowing the dust out, all power needs to be removed from the system at the very least.

Hi again,

So I've run the recommended tests and I haven't seen any errors. Temperatures seem fine. But I still get that occasional blank screen after I open a program. This usually happens near start up (within the first 5 min or so). I'm at my wit's end. I'm pretty sure it's more than just the screen turning off because when it turns blank, I try to press the start key, and then the right arrow, and enter because that usually highlights the shut down option. But the computer won't shut down. I've also tried pressing my power button once to see if that will shut it down (if the display is working fine, this usually does the trick) but that doesn't work either. Do either of you have any suggestions?

How did the memory tests go? Did Memtest86+ come up with any errors?

See if it possibly an application or service conflict. Troubleshoot Application Conflicts by Performing a Clean Startup

memtest86+ came off without a hitch. It's weird because I can't really pinpoint when it will happen, or what causes it. It's totally random ><

Alright, see how the clean startup goes and whether the problem occurs. Run it with the clean startup for twice as long as it normally takes for the problem to occur (use your best judgment as to the average time it takes since it is random).
