I acquired a ready-made setup from a builder and saw it in action. I connected it to a 650-watt power supply and added a GTX 970. After booting, the display isn’t showing anything from the GPU. The hard drive indicator stays lit briefly, then toggles on and off roughly every five seconds, and the keyboard light turns off at the same time. I’ve checked RAM placement and even tried reseating the CPU, but I’m unsure what to do next. Component specs: Intel Core I7 3770, 8GB DDR3, Gigabyte GTX 970 Windforce, Gigabyte P650G 650W.
Hi buddy, Continuous power cycling would say its a dead motherboard. I had an old 4770k system that did that and after managing to find another mobo that supported the CPU, dead mobo was the culprit. A few things to try before giving up as follows: 1. If you've changed the PSU, have you made sure that both the 24pin ATX AND the 4 or 8 pin supplementary CPU power cable have been correctly plugged in. It wouldn't be the first time I've forgotten about the 4 / 8 pin CPU power connector. 2. Have you tried removing the GTX 970 and seeing if you can boot with the onboard graphics. The 3770 has an iGPU so as long as your motherboard has an HDMI / DP port then you can rule out a GPU problem. 3. If you've tried to boot the system with nothing more than CPU, RAM, Mobo and PSU and you're still out of luck then try an 'bench-build'. Basically, this is where you strip the whole thing down and build it out of the case on you livingroom floor. This is a long shot but there's always a chance that a pesky screw is stuck somewhere and creating a short. Its always handy to have access to another system so you can swap components out back and forth to help diagnose. I think the problem you will have with that is its such an old system then unless you've something compatible up in the loft then you're $hit outa luck. Good luck
Hey there, did you attempt to boot without the GPU and rely on the Intel built-in graphics? Also, have you tested connecting a different power supply unit on another machine? Is that second PC also using older hardware—specifically DDR3 and 4th generation Intel? The goal is to pinpoint the issue faster, and swapping components can really simplify things.
