OK but it's just not happening. I can't work out if it's a power supply problem or a motherboard one. When I press the power button on the front panel of the case, the power supply and fans all power up for a fraction of a second, then die. This happens...

power supply to test. Any ideas? Thank you much. The most common problem in all builds is incorrect memory settings. Go into your BIOS and make sure the frequency, timings, and voltage of your RAM are correct. It sounds like a power supply problem,...

happens, either the motherboard isn't functioning at all or the power supply is shot. If your processor or RAM was no good, the motherboard should at least turn on and give you a beep code. If you have another modern power supply, you could try booting the...

the power supply to the motherboard. Video card and ram are placed correctly. However, this is a problem I've never seen before. With a plugged in power supply, I turn the power supply on (on the back of the psu), and then about 2 seconds later the CPU heat...

spin up, etc. After that the case switch works to warm start and I'm fine till the next unplug or power outage. Is this a MB problem or a power supply problem? I'm considering keeping my Antec Smart Power 500W supply for the upgraded system but not if...

website to double check power supply requirements. My 400W power supply does not have the same Amperage "maximum continuous" outputs as what they list for an optimal workstation. My question, before I go out and buy an expensive power supply to test this...

Yobigd thanks very much for your response. I dont know how to change the rails?? I only bought the power supply 2 days ago and don't think it is faulty, i had the same problem with the last power supply when i had only one card runn...

away, I have to wait for the timer to count down from 30... not that either does any good because the system hangs on a black screen right after that. Given this unusual issue, I thought perhaps this was an power supply problem. In theory this is a smaller...

the graphics card in place. My card was refurbished and may be the problem. I will see what happens when i plug the card in after the OS install. It seems obvious that the DiabloTek PHD650 650-Watt Power Supply was not the problem afterall. Perhaps you...
