Upgrading to a power supply with more wattage does not solve the problemīoth the working workarounds above are suboptimal to me - I prefer Windows over Linux and using analog connection leads to fuzzy image with my 1680x1050 resolution.The presence or absence of other monitors does not solve the problem.Tried changing refresh rate to 59, changing color depth to 16 bit instead of 32, lowering resolution.Playing with the monitor settings does not solve the problem.Also tried not installing any driver and letting Windows Update do its thing, didn't help.Using different NVidia driver versions - does not solve the problem.Using Linux instead of Windows - solves the problem.Tried clean installations of Windows 7, Windows 8 and Windows Server 2012.Using a different version of Windows - does not solve the problem.Connecting the monitor via HDMI instead of DVI - does not solve the problem.Connecting the monitor via VGA instead of DVI - solves the problem.Using a different monitor - does not solve the problem.This suggests a software issue, read more below. In addition, the computer sometimes gets a BSOD, blaming a driver issue for the crash. In these cases even quitting the application doesn't help, but physically disconnecting and reconnecting the monitor fixes the problem. Sometimes after the black screen, it won't return to normal, instead turning completely corrupt. This suggests a hardware issue, but read below. The frequency have slowly increased over the last few months - at the beginning it was every few minutes and only under load (watching videos / playing video games), now it's closer to every second. The frequency in which it occurs depends on whether there's anything moving on the monitor or if it's a static screen - flashing is less frequent when the screen is static, but still occurs. It looks very much how it looks when changing screen resolution. The computer itself continues running as usual. The entire monitor turns black, lasting for about a second, then resumes display as normal. Since then the monitor have been occasionally flashing black for a second or so, and I've been looking for - and failing to find - a solution. A few months ago I bought myself a new computer.
