Need help, old build won't display on monitor anymore

Potliv · Dec 31, 2014

Cpu: i7 4770 k
GPU: GTX 770
Motherboard: MSI Z97
PSU:CX600M

My build has been running fine for at least five months, but a week ago it stopped displaying on my monitor. Neither the onboard graphics or the GPU displays an image. The CPU and GPU fans run on high when I turn it on, and the case fans stopped working completely. I've checked the CPU and GPU and they both run fine and i also went ahead and replaced the motherboard with no luck. I've checked all connections and ran through the checklist but I still can't find the problem. Any ideas?

It could be a corrupted graphics driver. Try updating the graphics driver and see i that helps.

Also have you tried another monitor. It could be at that end as well.

The fan situation seems to be more of a BIOS issue. Try resetting the CMOS.

I've tried the monitor with another computer and it works well, tried resetting the CMOS but no luck. How would I know if I need a stronger PSU? The onboard lights on the motherboard flicker a little as if they're trying hard to stay on, it makes me think it might be a power issue

The GTX 770 system requirements are:

600 watt or greater power supply with a minimum of 42 amps on the +12 volt rail.

PCI Express, PCI Express 2.0 or PCI Express 3.0 compliant motherboard with one graphics slot.

One 8-pin PCI Express power connector or two available 6-pin PCI Express power connectors and one 6-pin PCI Express power connector or two available hard disk power connectors.

Your power supply (PSU:CX600M ) is at the level noted. But that series of Corsair power supplies are notorious for having problems (cheap components). I is possible that it is no longer putting out the necessary watts. You can try monitoring the voltage with an application like this one.

You can switch out the PSU with a known working power supply (650-750 watt).
Another way is to take it to a computer repair shop and have them test the PSU.
