So I just fired up my "new" build since I finally had time to assemble the parts. I test the powersupply when I had gotten it the first time. But when I connect the PSU to the motherboard, graphics card, optical, fans(3x yates, single 200mm fan), and hard drives.
It won't turn on for some reason, don't know why. Parts listed below, give me a clue on why it won't boot.

Antec 900
Tagan BZ700 modular
Q9550 C1
Biostar I45 Tpower
Patriot 2x2gb (1 stick inside currently)
Powercolor AX4870 1gb
Liteon multi drive
Seagate 320gb 7200.10
WD640gb ALS

All help is appreciated.

Thanks,
Mark
 
Did you test the psu with a meter?

Also you need to give alot more information when seeking help. Does it beep for ram. Does it beep at all. Did you try unpluggin your fan's and harddrive etc.. give us some more information. There are a ton of people waiting to help;)

Did you do any of what was in the the sticky

If your system doesn't POST...

This is basic troubleshooting if your system has never POSTed (as in, you just put it together); Though, it may be helpful to others whose system no longer POSTs...

If you have both the 20/24 pin main ATX connector plugged in, AND the 4-Pin (or 8-pin) ATX12V P4 CPU connector plugged in, then the board should boot fine (unless it requires more power connectors from the PSU). First, try clearing the CMOS w/ the proper jumper or button.

The next thing you could do is test the PSU. Jump start it (on the main atx connector, short the green wire with any black wire, using a paperclip), and see if it stays on. If not, then its probably a faulty PSU. If it works then you can proceed with the suggestions below. ***NOTE: The paperclip trick is a simple test for those that do not have PSU testers, multimeters, nor a spare PSU to test with. It is not a 100% conclusive test of the PSU.

How to test with a multimeter @ BFG

Setup everything outside of the case, with the mobo on top of its cardboard box. Plug in only the essentials: (this is also known as a barebone bench test)
- PSU (namely: main 20/24-pin ATX connector and 4-pin ATX12V P4 CPU Connector; The 4-pin should work in the 8-pin EPS12v plugs, too)
- CPU w/ HSF
- Single stick of ram
- Videocard if there is no onboard video (along with its molex or PCI-E power connector, if it has one)
- System speaker/buzzer (your board may have an on-board buzzer/speaker)
- Monitor & Keyboard

Reset/Clear the CMOS by following the instructions in your mobo manual.

* Use a screwdriver if your board doesn't have an onboard power switch. Jump the two power switch leads to turn the power on (connect both pins for 1-2 seconds with something conductive).

If it won't POST, try different RAM slots. If it still won't post, pull out the ram (so no ram in the system) and listen for error beeps. If none, pull the vidcard and listen for error beeps. If none, re-seat the CPU and HSF, then try again. Report back with results if you're still having issues.

also you should always test your system outside fo the case a table is a good place to start something wooden.
 
With the exception of the CPU/fan, strip the motherboard down. No USB's, no CD/DVD, etc; just the CPU/fan. Discharge the motherboard via power button while touching chasis. Now remove the CMOS battary and clear the CMOS by pin. After clearing the CMOS and replacing the battary put one VGA in the primary slot and one stick of ram in the B1 slot, now see if you can post. Make sure you set your ram voltage to manufactures specs. After you have taken these step the motherboard should post.

everything is connected correctly. the pc just doesn't turn on.

If you read the post, it asked you to report your results. As Sathsayin said, we need more info...

  1. Did you benchtest this system outside of the case on a non-conductive surface? (this eliminates common problems with something shorting out the system from within the case)
  2. Were there any fluctuations when you tested with a multi-meter?
  3. If you didn't use a meter, how did you test it?
  4. Do you have a system speaker plugged in?
  5. ...Did you get any error beeps without the vidcard?
  6. ...Did you get any error beeps without the RAM?
  7. ...Did you get any error beeps after you re-seated the CPU?
  8. Do any fans spinup?
  9. Does the PSU fan spinup?
  10. Do any HDDs spinup?
  11. Did you clear the CMOS?
 
1. no
2. don't have one
3. Paper clip trick
4. I didn't have speakers plugged in.
5. no
6. no
7. no

These were connected when I turned turned on PSU with no go.
8. no
9. no
10. no
11. don't know how to do that on biostar I45, I will check out when I get back from church.
