DIAMELO Posted October 23, 2013 Share Posted October 23, 2013 Alright so lately I haven't been on because I've been having some really bad computer problens. It all started about a week or 2 ago when my gigabyte 970a d3 motherboard toasted. I was playing bf4 beta and while in a match my PC turned off, I let it sit for a couple minutes thinking it was just a bit overheated. When I came back to turn it on all the fans and LEDs turned on just fine but the fan on my GPU was spinning faster than normal and there was no video. So I left it for another while and then I came back and tried again , this time nothing happened, no power. So I order a new motherboard, a gigabyte 990fx ud3 board, it arrives and I hook it all up inside the case, connect the power and press the power button. This time the system would only stay on for a second, all fans and LEDs come on but only for a second and then power down. So a dead mobo right? Next go to Fry's and pick up an Asus crosshair v formula z board. Brand new board, hook it all up again connect power and press power button ...fans and LEDs come on, no video but GPU fan is spinning fast, no beeps no error codes. Now before you say its the GPU I did try 2 other GPUs and all 3 act the exact same way but when I install them into another system they work fine, fan spins at normal speed and there is video. System specs: Motherboard: Asus crosshair v formula z CPU: fx8120 GPU: amd radeon HD 7970 PSU: corsiar cx750 RAM: corsair vengeance 8gb So now I'm here to ask if anyone on the forums would happen to know what's going on. I did try powering on the system without the CPU and ram in but the cards still acted the same. I really need to get this firgured out so any help/feedback is appreciated, thanks. If you need anymore info just ask. Quote Link to comment Share on other sites More sharing options...
KarmaOfPain Posted October 23, 2013 Share Posted October 23, 2013 Have you tried using a different psu to rule out if its your psu causing the problem? Quote Link to comment Share on other sites More sharing options...
Short Posted October 23, 2013 Share Posted October 23, 2013 Have you tried using a different psu to rule out if its your psu causing the problem? He just picked up that psu to make sure it was not. Quote Link to comment Share on other sites More sharing options...
DIAMELO Posted October 23, 2013 Author Share Posted October 23, 2013 Have you tried using a different psu to rule out if its your psu causing the problem? Yeah I forgot to mention I had a cx600 from corsair in there and I just got a new cx750 to try and its still acting the same. Quote Link to comment Share on other sites More sharing options...
enigma# Posted October 23, 2013 Share Posted October 23, 2013 So I assume you're using the same case? It is suspicious that failure would occur on multiple replacements as it appears that it may be case. Have you tried powering it on outside the case.

BranHorse Posted October 23, 2013 Share Posted October 23, 2013 The mobo should have a power button on it, turn it on from there. I know the 990fx ud3 does. The asus probably does too. I think you might be simply missing a power connector somewhere. Build it outside the case, post pics of the wiring. Quote Link to comment Share on other sites More sharing options...
DIAMELO Posted October 23, 2013 Author Share Posted October 23, 2013 Yeah I tried it outside of the case and it still did the exact same thing, powers on no video but GPU is still going fast no beeps or errors. I tried the same thing when I got the gigabyte ud3 thinking there was some sort of short inside the case and it still did the same. Quote Link to comment Share on other sites More sharing options...
