Ok I have all brand new parts, EVGA p55v motherboard, Intel core i5 750, bfg geforce 9800 gt, 500 GB segtate sata HD, Lite on dvd drive, and a Hyper N520 after market cpu cooler. I have built a few computers even more complex than this one in recent years this is for a friend but for some reason when i turn the computer on all the fans including the psu cpu and extra led fans i bought all turn on for 2 secs and then shut right off. If i leave it alone it will turn back on after about 5 seconds and then shut back off after 2 seconds and repeat the process over and over. I have the ram in the right ports according to the manuel installed the cpu and fan correctly took off all adhesive stickers and have all the front panel switches correctly in place. I am hoping that its just not enough juice but I am using a cooler master extreme power plus 500w psu. Any suggestions? Thanks
When I take the graphics card out and unplug all the drives the same thing happens. There is also a delay from when i hit the power button to when the fans start spinning like 2 seconds any other suggestions?
I read that first before I posted and I believe I followed eveything on that check list. I am just wondering if 500w is enough to power that type of cpu and graphics card and if so what else might be the problem cause I can always take the psu back and upgrade for a few bucks more. The graphics card is one of those that doesnt require a power attachment and I havent used those in the past. Has anyone heard anything about that bfg geforce 9800 gt?
The PSU is strong enough in theory to power the system, so a bad PSU could be an issue. The Cooler Master isn't the best of PSU's. If you have an option to exchange and upgrade to a Corsair, Antec or SeaSonic PSU, it may be worth starting with a new PSU. This is granted you completed the checklist and could not determine the issue.
I've been in tech support, for 25 yrs and I have never once seen a bad MB !
I decided to take your advice and i stripped everything down and with a new 750w psu I am able to get the computer to start up and stay on but only with the graphics card and heatsink plugged in when i plug in the hard drive or cd drives i get the same old result shutting off after a few seconds and restarting any suggestions from here.
