Question about DFI Computers & Internet
I bought a DFI Infinity NF4 SLI on eBay (seller has 96.3% positive feedback). I moved it into a case that had been running a DFI Infinity NF4 Ultra until it got stuck, perhaps heat related. The SLI turns on for less than a second before turning power right back off.
DFI tech support suggested I clear the CMOS setup RAM which I did (over night). It still behaves the same way. All the fans spin up for a moment then stop. Most drive lights come on for a moment then go dark. I even went so far as to unplug everything: video, RAM, storage, front panel lights, ... Only the CPU, PSU, and power switch were still connected. It lights up for a moment then goes dark and silent.
The standby power light near PCI slot 3 is on. The RAM power light comes on momentarily with the fans and other lights.
What do I do to make this come up?
Hi steve, PC repair is trial & error. I suggest you replace the power supply or test the power supply in another PC that also uses 4 SATA drives & two PCI-E slots for starters. Two boards with the same problem is odd. You must have the CPU & fan connected, memory installed, ATA 24_pin main power plugg connected (Page 17 in manual). 4-pin_12v power connected which is located (Just to the left of DDR1 memory slot). Looking at you're board the power supply should be no less than 500w.
CPU must have thermal grease between CPU & heat sink.
Even though you have fans running & LED's on & flashing, the power supply seems to be the first item to check. Make sure the bottom of the motherboard is not touching the PC case.
Try the above & post you're finding here.
