I noticed it was 2 red lights inside the amplifier, what does it mean?

The amp has 7 LED's in total 4 whiteLED's provide back lighting
the bi-colour LED white/ amber is the power/standby indicator (amber when amp is in standby mode)
The two red LED's are on the Phono Board and form part of the phono amplification circuit.( D1 & D2)They are NOT fault indicators and should be lit during normal operation.

I have 9 wire from my front of my case &2line USB in the names are SHIELD/GROUND1/GROUND2/-D1/-D2/+D1/+D2/ +5V1/+5V2 & Ihave 9 socket on my mainboard IWILL P4S from plug in the wires there are...

Refer to the drawing below and I will explain the connections. You have the nine wires as you described. First, you will not be connecting the SHIELD to anything, so set it aside. Now, the remaining 8 wires are split into 2 groups of four. You have +5V1, -D1, +D1, +GROUND1 on the first group. These wires will attach to the ODD pins 1,3,5,7 respectively (see the chart next to the drawing). Use the missing pin location to orient yourself to the EVEN and ODD pins. The remaining wires +5V2, -D2, +D2, and GROUND2 will go on the EVEN pins 2,4,6,8 respectively.

Hope this helps!

My daughters Toshiba satellite l505d will not boot up correctly. It starts but then nothing happens. What do I need to do. Have already taken battery out and restarted. Any help would be helpful.

Try the following.
1. Remove battery and plug in the AC Adapter and check if it works
If yes - Battery is defective
If no - Motherboard Problem/AC adapter

2. Check the AC adapter LED indicator if its lighted or not(double check by a multitester)
If lighted - it works properly
if not - replace
3. Try to reinstall WINDOWS operating system by the use of the installer CD
4. Reformat your computer and install necessary drivers and applications

Thanks. Cheers!

1 TB Esata/FireWire400/USB 2.0 disk problem, one flashing light

have you checked the output on the power adapter when you plugged in? if not, there is no hard reset for the drive. you just have to isolate the board on you external hdd.

Just installed motherboard and processor powers up led is on top 4 and botom 2 what does thst mean?

not sure what your asking but if the wrong lights are staying or or not coming on it is because you placed the LEDs on incorrectly. check your manual for the configuration and verify that when you place the connector to the board you have the polarity correct. LEDs are polarized and the electricity can only go one way to make them operate correctly

You should have told me you are missing a manual. If you dont follow thing from it correctly, you can really burn your motherboard. from the usb connectors on the motherboard
you see pins like this 1 is set 1 and 2 is set 2. you see those are wrapped in sets from you cable near the end. dont mix them

ooooo 12345
oooo 6789

lets put it this way

vcc1 = 1
-d1 = 2
+d1 = 3
GND1 = 4
nothing on 5
vcc2 = 6
-d2 = 7
+d2 = 8
GND2 = 9
