The first thing to do is get another psu and try it. If that doesn't do it then perhaps you had a power surge and toasted the mobo. Do you plug into a quality surge supressor?

530w is plenty of juice...some do go bad. Can you get ahold of another psu to try to at least eliminate it as a possible issue?

is there any other way i can tell if it was the mobo or psu

there is a few reviews on new egg that says the psu dies after working for a while ( http://www.newegg.com/Product/Product.aspx?Item=17-152-... )

I am hoping its not the mobo the onlything that might of done it is i turned the surge protector off and on to restart my router but the computer had been off for well over two hours at that time.

If you are using a multi plug in cord to plug your system into check to see if it needs reset. Simple i know but hey worth a shot lol

Either your PSU or your motherboard is dead. My money's on the PSU, since they're much more prone to failure. Don't even need a surge to kill them, they just kind of die sometimes. My rig is very similar to yours, and I've blown multiple PSUs. I don't buy any PSU cheaper than $60 anymore, they just don't last.

Lucky for you, there's a very easy way to test to see if your PSU is totally dead or not.

*Disclaimer*

I am not responsible if you do something stupid and electrocute yourself. If you follow my instructions, you will be fine. Don't go jabbing paperclips into any of the other pins, though.

*/Disclaimer*

First, go find a paperclip and straighten it out. Needs to have bare metal exposed. If it's coated in rubber, use some sandpaper or a knife to expose both ends.

Next, unplug the 20/24 pin connector from your motherboard. You probably want to unplug everything from the PSU to be safe.

Here comes the fun part. Look at that 20/24 pin connector. You'll see exactly one green wire, with a black wire on either side of it. Take your paperclip and insert one end into the pin for the green wire, and the other end into one of the black wires (doesn't matter which).

If your PSU works, it will turn on. If it's dead, it will just sit there like a brick.

You can buy a cheap PSU tester which can tell you if the PSU is good or not.

One of my rigs also had a power issue where if it wouldn't boot, i had to physically remove and re-set the ram modules before it would power up. I never figured out why, but i suspect it was a mobo firmware bug that set some sort of self protect feature.

Anyhow, you can try that to see if it helps at all too, But if i recall the LED's would at least come on, just the Bios / Post would never run.

Take the box with everything in it to a local pc repair shop and ask them to test the psu.

My computer did randomly reboot itself a couple of times the day before it stoped powering up does that mean anything?

Doesn't really help. Could be any of the items failing. Power drop, ram hitting a bad spot, a video card going out...may be time to get some local help.
