Video card not enabling unless power cables reset

[Dunkinator]

Hi there,

I have a Geforce GTX570 connected to a Coolmaster 750W power supply. The machine has run flawlessly since I built it. However a few days ago, the display failed to re-initialize after trying to wake the machine from sleep. Upon shutting down the computer and restarting, I still had no display.

After an exhaustive series of tests, I found that if I removed the two power cables connected to the GPU and then re-connected them, the display worked when I next booted the machine. Now switching the machine off and on again is a bit hit and miss - sometimes the display starts, sometimes it doesn't. Each time reconnecting the GPU power solves the problem. Once running I've experienced no problems and ran 3D Mark multiple times to try see if there were any issues - there were none.

Anyone experienced something similar? Could it be video card failing? Power unit failing? I've resetted the BIOS as I thought it might have been some strange standby issue.

Any help would me most appreciated!

Could be the PCB's electrical joints on the 6 Pin power connector drying up, lose connection.

If your feeling brave with a soldering iron it should be fairly simple to heat up the joints and reseat them.

Its a 570, its probably out of warranty? but yeah point taken. if its still in warranty send it back.

Snap I missed that

If not in warranty then it's worth trying to re solder the power pins
