It is the problem with your motherboard and not with the Power supply. I know It sounds silly but this is true. Please get the motherboard repaired

My start/resume light keeps blinking


Count the blinks. If 7 blinks, this usually indicates a problem in the heater circuit. You have to be able to check your heater, heater thermostat and possibly your control board.

sometimes you can shut power off to dishwasher for 10 seconds and this may reset your control and allow your dishwasher to run until the fault reoccurs.

I have a DFI LanParty NFII Ultra motherboard. I had to move the power supply to a different machine and have purchased a new one to drive the DFI system (Win Power) rated at 650w. The power standby...


It's the craziest thing, I'm looking dead at the Motherboard Manual for the DFI LanParty NFII Ultra B motherboard, and the diagnostic LED lights are Not referred to.

Looking at the view of the System Board, the LED lights are shown down by the CMOS Battery.
LED 1, 2, 3, and 4.

The manual indicates only two types of BIOS Beeps are listed;

1) One Long beep followed by Three Short beeps.
Video error has occurred and BIOS cannot initialize the video screen to display any additional information

2) Single Long beep
A DRAM error has occurred. {Problem with the Ram Memory modules}

The BIOS program is a Phoenix - Award BIOS, but doesn't indicate what version or date.

[ The motherboard manual is downloaded for free from here,

http://productsmanuals.com/computer-manuals/dfi-lanparty-nfii-ultra-b-system-board-user-manual

Go to > To view the Products Manual - or to Download it - just click HERE.
{Click on HERE}

Allow up to 30 seconds for the file to download.

Offhand I would say it is Ram Memory that is the problem. Remove the ram memory module/s, and clean the gold plated contact pins with a pencil eraser, then use air to remove the eraser dust.

However, in looking up for information on the diagnostic LED lights, (The info IS out there. Maybe on DFI's support website, but I couldn't find it), I see that if you are using a graphics card that requires an additional power cable, you'd better have that baby plugged in.

The motherboard won't work if the additional power cable isn't plugged into the graphics card.

Power light on the amp goes on after 5 sec off ultra linear 1200


If you run the remote from the battery you will need a on/off switch. Sounds like the amp is overheating. Also, I don't understand bridge the remote and power. They should be seperate going into the amp.
