Ok, so its not the PSU... STILL Dead!

Ok, lets try this again. I need to save my baby.

Here is my build:

AMD Phenom II X4 955 Black Edition Deneb 3.2GHz Socket AM3 125W Quad-Core Processor

ASUS M4A88T-V EVO/USB3 AM3 AMD 880G USB 3.0 HDMI ATX AMD Motherboard

SAPPHIRE Vapor-X 100284VXL Radeon HD 5750 1GB 128-bit GDDR5 PCI Express 2.1 x16 Graphics Card

APEVIA ICEBERG ATX-IB680W-BL 680W ATX12V / EPS12V SLI Ready Power Supply

Kingston HyperX 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 Desktop Memory Model KHX1333C7D3K2/4GX

It started a week ago when the screen blanked and I could not restart my PC. I thought it was the PSU because of how it was acting. I tried to restart but when I did only the fan lights, system lights, and my cathodes blinked and the fans kicked for a split-second and barely moved and then nothing.Pressing the power button after the initial try did nothing at all. If I pull the power cable and powered off/on the PSU, it did the same split-second power up before no response again.

Now, I took out the video card and it allowed me to start the system to much rejoicing... for about five seconds...

Fans and lights come on but it still won't boot or give me a display using the onboard DVI port. The HDD is spinning but not doing anything else and the reset button does nothing. I have unplugged both the HDD and the ODD, Taken the system down to nothing more than the MoBo, CPU & Fan, RAM, and two case fans then started it up. Still nothing. My dilemma is that I do not know if which component it is and I hate to spend money I don't really have on parts I don't need or by that token, spend money on lets say the motherboard and blowing up the new one because I didn't fix the issue. Right now I am just throwing it out there to see what you guys think. I have reset the bios and tried pretty much everything I can think of.

Sad to say mate, I think there's a high likelihood of it being your PSU.

That brand is one of the most terrible PSU brands you can get your hands on.

Thus even IF you got it to work, you ought to still change your PSU.

Check tier 5 and you'll find yours.

What makes you feel that your power supply is not the problem? Your power supply is at the bottom of the list ( Tier 5-NOT recommended ) in relative quality:

Have you borrowed someone elses or purchased a PS tester. There are cheap testers on NewEgg. Have you tried each stick of RAM separately?
Here is the standard list of items to check. You may need to go over this carefully even if you have done it before. Not fun!

i'm not saying you are wrong... just that it seemed to work when I pulled out the video card. At that point it allowed me to turn on the machine which is more than it would let me do before. Do you know why this could be? It would help if I understood why the video card had to come out to even turn it on...

everything plugged in = the fan lights, system lights, and my cathodes blinked and the fans kicked for a split-second and barely moved and then nothing

remove video card = it fired up and stayed on.. kind of. Still no video or signs of life from MOBO.

thanks to everyone for helping me!

Your PS is not dead, there are many rails, 12v, 5v, 3v, -12v, etc and PS may have a leaky capacitor or any problem that allows to still work, but not put out full power. Your video card draws at least 75 watts even to fire it up, much more when gaming and your PS is likely barely putting out enough power to run you CPU at idle. A new PS is inevitable. Even a cheap Corsair CX500 watt would work fine. This one is $40 after rebate!

you should try to borrow a decent power supply. from another one in the house, from a friend, from a neighbor. But it has to have enough power to run the system. The one you listed gets bad reviews.

the motherboard got terrible reviews.

while it's down you should pull the heat sink and fan, clean it up, reapply new thermal paste and reassemble.

can you hot swap the HD to another machine and check it for errors?

also for the sake of argument, try plugging into a different wall outlet.

PS or MB...........???

Have you coNtacted the power supply vendor to see if they do advance replacements. Where they ship you a new power supply first....you then can use it for testing.if it fixes your issue you return the doa power supply. If not at most it going cost you a shipping charge if the old power supply is still under warranty.

So what you are saying is that since the supply is going bad, when I try to boot with the video card it auto shuts down due to the power problem? I never knew how much power I needed... based on my specs would 500 work?

Not under warranty.... : ( but then I think I have a friend with an extra supply. Even if its not a popular brand it works and it will test out. thanks for the comment!

Heat sink and fan - already did that because to your point it just makes good sense. I redo the paste every 6 months because its cheap and smart.

When I bought the board it didn't have such bad reviews... which I chalk up to live and learn :p  I hope to not have to replace the MOBO or CPU but if I do I will know better next time!

When you try the power supply if it does not work still try different RAM slots try each one with different memory sticks :)

I believe the DRAM voltage needs to be 1.65v and the memory clock and timings should also be set manually.

500 Watts would be fine, however, I am of the camp that larger power supplies even though technically unnecessary in actual wattage needed, are far more efficient, with less heat and lower ripple. Clearly a higher quality larger power supply costs more. I did a lot of studying before I made my last PS purchase, a Corsair AX750, replacing a perfectly good, but old Thermaltake 500 watt PS. The Corsair runs significantly cooler and the specs are exemplary. I justified it because a PS is a very long term purchase that will last through many builds and likely 7 or more years, so the cost can be leveraged over time compared to all the GPU's, CPU's, MB's and RAM that will be replaced over the same period of time! My system is a 8350 @4.7 / 6950 / Asus M5A99x / Crucial 1866 8GB. The 500 watt supply was fine, but moved to a HT build. Interesting fact: A 1000 watt Gold PS will use notably less power (and run cooler) from the wall putting out 500 watts than a 550 watt 80+ PS putting out the same 500 watts! It's all relative, but I am saying you should consider spending proportionately more on a high quality PS than most other parts considering it's long term investment!!!

Thank you so much for replying. If I have to buy a new supply I will make sure to research my options. I can build computers and fix them but I never considered all of this when it came to power supplies. I just bought one that I knew would have enough power but I had no idea how to really dig into the details about it. I have my brother in law bringing a 500w PS that we know works over to my house in the next few days to test my system. Check back to see if it worked!
