Sep 15, 2019
Hello..i just build i new PC and when i turn it on without the grafics card the pc works fine but when i pluged it in and press the power button it doesnt starts and then when i remive the grafics card it doesnt get any power. It did start one time only with the grafics card that i installed the windows. I think the problem is in the cable because where the power suply is it doesnt have so much space but i dont know. If you anyone can help me it would be grate.

Provide FULL PC specs.

-1. "Complete" system specs should ALWAYS be accompanied with any driver, hardware, or performance question. Do not post DXDiag reports as they contain a TON of useless information. Posting a DxDiag in place of a System Spec List tends to ward off potential members from helping you.

Please supply the following system details/information:

(Complete System Specs)
-CPU make and model# (clock speed/voltage, type of cooler, and "Core" temperature @ idle and load)
-Motherboard make & model# (include Bios version if graphics card is not recognized or you are having stability issues)
-RAM (amount, clock speed, model#/link of kit, configuration)
-Graphics card(s) make and model# (clock speed, voltage if modified, Driver version and GPU temp both @ idle and load)
-Power supply make,model#, "AND" age (note if using 110V or 220V A/C input)
-HDD/SSD configuration (ie: Raid setup/ back up/ OS drive/etc..)
-Case/Chasis make,model# (fan make, model#, and configuration if having thermal issues)
-Operating System (If using Windows note Framework and service pack version)
-Monitor make, model#, and resolution (If model# is unknown list resolution and refresh rate)
