A wile back my computer popped and stopped turning on and the motherboard light would not light up. I replaced the power supply and after matching all the plugs the motherboard light would turn on but the computer will not. If i don't plug in the small 2x2 power cord to the motherboard the computer turns on but there is no display.

btw my power supply is an apevia iceberg power 680w
my motherboard is a nvidia socket am2 mATX motherboard
my video card is a nvidia geforce gtx 280

Is it possible that other components were damaged and need to be replaced?
If so, what tests do i need to preform in order to be sure before I invest more into replacing them?

At this point the only component you know is good is the powersupply. It is a worry that the system will not respond when the 2x2 connection is in place yet it does respond when that is disconnected. That connection is supplementary power for the CPU. It may mean your CPU is toast or the motherboard. Your graphics card may also have been fried when the system shorted out. Unfortunately when powersupplies blow they can cascade through the whole system. Unless you have spare components you can swap in/out your best option at this stage might be to take it to a technician to have the components tested.

"A wile back my computer popped .."

That was probably a defective capacitor inside the power supply that exploded.
El-cheapo power supplies are a lot more likely to have defective capacitors that were not properly made in the first place - they work fine for years, then the fluid inside breaks down - they eventually get a bulged top, may leak fluid, and they can explode when they deteriorate to that point.

What was the original PS brand ?

Some brands are well known to be more a lot more likely to damage the mboard or other components when they fail.

nvidia geforce gtx 280

NVidia info :
Minimum Recommended System Power (W) 550 W
Supplementary Power Connectors 6-pin & 8-pin

On another web site:
550W PSU with 40A on the 12V rail.
the GeForce GTX 280 uses one 8-pin and one 6-pin PCI Express power connector.

You MUST connect both the 6 pin and 8 pin connector from the PS to the video card's sockets.

If the PS does not have an 8 pin connector, you probably need to get and use a wiring adapter that does have the 8 pin connector.

The power supply MUST put out at least 40A at +12v, total . ( If it has more than one +12v output rating, add them).

If you're a gamer...
In most if not all cases, the max capacity rating of the PS is an intermittent rating. It's recommended that you do not load your PS to any more that 80% of that rating if you are going to be using something that puts a constant load on it, such as playing a recent game for hours on end. In that case, you multiply the min capacity stated for the system with the particular video chipset on the card by 1.25 to find the min. capacity of the PS you should get.

550 x 1.25 = 687.5

You're alright regarding that.

You may have un-intentionally loosed a connection or jostled the ram. Make sure all wiring connections on all the way, and that the ram and all cards in slots are all the way down in their slots.

You could remove the wiring connectors one by one, and remove the cards in slots and the ram, and check for signs of damage on both sides of the connection.

If it's any consolation, if something was fried, usually only the mboard is fried.

Your 64 x 2 3000+ cpu
correction - 6000+
can be used in any AM2 + or higher mboard that can handle the wattage of it - you may have the original 125 watt model, or the one that uses less power. That's a great cpu for it's time, by the way.

Your ram can be used in any mboard that DDR2 ram can be installed in, or the cpu can be used with faster ram at 800mhz.

I checked all the connections and then tried with the 2x2 plugged/unplugged with the same results. I noticed that the large 2x10 power connection to my motherboard is actually a 2x12. Do i need to plug the 2x2 and the 2x10 that my power supply has into the 2x12 and then convert a spare 1x4 into a 2x2 for the other slot?

My old power supply (which was successfully replaced once for failing) is a epower xtrem ep-400xp 400 watt

Your .1X ... and ..X2 or 2X... terminology is not normally used. Connectors from the PS for the mboard or video card sockets and matching sockets are mostly if not all double row. Connectors for the drives are single row.

The shapes of the plastic around the pins or contacts on the plugs from the PS and the holes in the mboard (or video card) socket or drive socket etc. are shaped such that the (male) connectors from the PS cannot be installed in the wrong place.

You DO NOT convert a spare 1x4 into a 2x2 for the one end of the 24 Pin" socket. It does not have all the proper wires / voltages.

If your main power socket on the mboard has 24 "pins" - a double row, 12 each side - you must plug in the suitable power supply connector(s) into all the positions in it - usually the main power supply connectors from the PS (male) are a 20 pin plug and a 4 pin plug in the same wiring bundle, rather than being a one piece 24 pin plug, although the 4 pin plug may be clipped onto the 20 pin one when you get the PS - the 4 pin one and the 20 pin one for the main connector socket will fit in only one place, one way, in the 24 "pin" socket . No other connectors from the PS will fit in that socket. The same goes for the other sockets. You can't plug in any connector from the PS into a socket it wasn't designed to fit in.
If your PS is an oddball that has only a 20 pin connector and does not have the 4 pin one in the same wiring bundle beside it, you must get and use a standard 20 "pin" (female) to 24 pin (male) wiring adapter , plug the 20 pin connector from the PS into it on the 20 "pin" end, and plug the (male) 24 pin connector end of the wiring adapter into the (female) mboard socket. There must be at least one wire in each of 23 or 24 positions in the 24 pin (male) end of the wiring adapter. There may or may not be a white wire in one hole - it's not needed if the mboard has no ISA slots, and it does no harm if it's there and is not needed.

"(idk what wattage unfortunately)"

If you still have it, the capacity is stated on it's label as max total watts (output) or similar . The original specs of the system, including the PS capacity, may be on the web somewhere. Brand name system often use the same capacity PS for many possible video cards, if more than one was available. .

It's quite likely, if you originally had the 8500 GT video card, or another meagre video card, that it did NOT have enough capacity to handle your GTX 280 chipset on this video card. The former requires merely a PS with a minimum 300 or 350 watt capacity.

I bet your right about me not having the capacity for the upgraded video card with the old PS. I discovered that what i thought was a 8 pronged cord was actually 2 4 prongs connected. Once i plugged that into the motherboard it booted up and had display.

Btw thx for all the detailed information on what components are compatible with my system. I will probably be upgrading order to keep it competitive.

Hooray ! That's good to hear !

Pictures (that would have saved me a lot of typing in the above last post).....

The typical pair of 20 pin and 4 pin connectors from the power supply for the main socket on the mboard
The plastic shapes around the pins on the 4 pin connector beside the 20 pin main connector is different from all other 4 pin connectors from the PS.
Shows the typical standard wiring colors, and the voltage or signal for each one

When you get the PS, the 4 pin connector of the pair can be
- already clipped onto one end of the 20 pin one, or otherwise fastened; the 4 pin one is removable.
- separate but near the 20 pin one - the 4 pin one may have no way of fastening it to the 20 pin one, but it and the 20 pin one may have a marking to show you which side and end go next to each other (they only go into the socket one way in one place, in any case)
- separate and tied back - the wiring of the 4 pin one may be looped away from the 20 pin one and secured to the bundle of wires that is common to both connectors , e.g. with a zip tie or twist tie - so that it isn't in the way when only the 20 pin connector is used.

If you truly do not have that 4 pin connector, you need a wiring adapter like this....

updates -

If the second mboard power socket is 8 "pin", then you can use either this 8 pin connector or these two 4 pin connectors in it
EXTX12v (8 pin) wiring connector picture

Note the shapes of the plastic around the pins of the left connector of the 4 + 4 12v cable - if your second mboard socket is only 4 "pin", which is common for older mboards (and newer non-Intel cpu mboards) then the needed 4 pin ATX 12v connector is exactly the same as the left connector (and it can be plugged into one end of the 8 pin socket).

Better view of the plastic around the 8 pin connector pins here:
(It's a wiring adapter that can be plugged into what you called a 1 x 4 connector - the proper name of what you called a 1 x 4 is is a molex connector, a power connector e.g. for hard drives - MFM, RLL, IDE, and early SATA - or desktop IDE optical drives.
The one on the right is the not common, except for on one end of the 20 (female) to 24 pin (male) wiring adapter, one piece 24 pin (male) connector for the 24 "pin" main power socket on the mboard.

As I said, your cpu is a GREAT cpu for it's time.

I have installed two 6000+ and it's sibling a 6400+ on other people's computers, all were the 125 watt model, the lower power 6000+ wasn't available yet, and I was and still am impressed with the performance of both.

You are probably not going to need to upgrade that, unless, possibly, if you MUST play the very latest high end video games. There were very few cpus like the 6000+ and 6400+ that operate at 3.0ghz and 3.2ghz respectively that perform as well as they did / do. ( 6000 and 6400 are AMD's approximate rating of the cpu's perfomance in mhz in comparison to Intel's original P4 cpu. )

The person who I built one of the 6000+ computers for died, and I acquired her computer from her Dad in June of this year for free, because she owed me a lot of money at the time. The mboard it is installed on was upgraded twice, the first time because I couldn't get the NVidia drivers for the main chipset on the first mboard (Asus) to work properly with an ATI AIW card I got a great deal on (the card was worth more than the mboard), the second time because a local power failure event damaged the PCI-E X16 slot circuits (Epox, the last full size ATX AM2+ model they made before folding) and that same ATI AIW video card. The 6000+ is presently on an Asus M3A78 Pro mboard, with 3gb of 800mhz ram, a Visiontek HD AIW video card, and it's running Vista Home Premium and XP MCE 2005 (both are 32 bit), via a third party boot manager program (BootIt! NG) . The M3A78 Pro mboard is compatible with MANY newer cpus including the 6 core Phenoms, but, so far, the 6000+ performs so well, I see no reason to upgrade to a newer cpu. On the other hand, I don't play recent high end games.

(She could move only two fingers and needed to be able to use a touchpad mouse to watch TV, so that's why her desktop computers had AIW cards - she LOVED Media Center's TV card support. )

The 4gb virtual memory address limit for 32 bit operating systems.
An example of 3gb working better than 4gb in a 32 bit operating system. That was done on the computer I installed the 6400+ on, 3gb of ram, XP Home, Sapphire HD 4850 video card.
See Response 6:

By the way, multiple core cpus are hype.
Most people have few if any programs that can use more than one cpu core.
Server operating systems, high end very expensive scientific or graphics or animation programs, etc. can use more than one, but most people don't have such.
A common exception to that is some recent and fairly recent high end games, but as far as I know, the multiple core support can only be used in Vista and Windows 7 for them, and I haven't heard of any that use can use more than two cores.
So - dual core cpus are fine for most people, at the present time, if you're running Vista or Windows 7, and you want to use something, such as high end games, that can use more than one core.
