Windows 7: Windows 7 Monitor receives no signal after a while of functioning

Windows 7 Monitor receives no signal after a while of functioning

Hi all.

I encountered a new issue with my PC and I sincerely don't know what to do. In fact, after a while, the monitor is showing no signal. I changed the video card with a brand new one and still my PC will do the same. Is there a worm or software issue or the motherboard miss-fires?

Thanks a lot!

first, check if the monitor works with other PCs.

sorry, i should have pointed the following actions:
- i changed the cooler paste from the processor
- i added a new fan
- i cleaned and dusted everything
- i tested the monitor on another computer
- i changed the video card (upgrade it)

So i really don't know what to do next. I just want to know if this can be a software issue as well as a hardware one. I suppose that I'll change the power supply and/or the motherboard, but after being sure that it isn't a software /worm/malware issue.

if the monitor doesn't display nothing after doing what you did, 90% is an hardware problem.

If you have it, try using your integrated graphics card without any other graphics device in PCI/AGP/PCIe slot.
