A couple of days ago 1 of SSD crashed while I was playin hard reset. I reinstalled OS n all just to check any software mishaps, but it crashed again
 
two thing will do that one a pc a dead short. the power supply and mb can tell there a dead short and will shut off to save your system from frying. the power supply has failed. it giving you an output but not handling the load and shutting off. or somthing in the ps like a cap has failed. if the ps under warranty i would rma it first. or see if a friend has a spare.

Reset your BIOS by removing all power sources (power cable, monitor, and powered speakers, then pushing the power button to discharge any residual power, and then remove the motherboard battery. Wait 1 minute and reverse these directions.

When you restart the system, the BIOS will be in its default config (no OC for memory or the CPU).

Hi,

in my opinion the PSU (500W) is actually quite small for the specs you've given. I'd try a bigger one, at least 650W or even more. Borrow one if possible before you buy and confirm if it solves the problem.
Why? Even *if* the PSU was coping with the load for some time, it was probably on the edge. Components might have suffered from excessive loads over a lng tie and therefore slowly burned out. Especially if something changed in your environment, like having higher ambient temperatures than before that might have triggered the final failure. Also consider testing with onboard graphics/another graphics card. You might have a problem there.
I had a similar problem in the field, with a similar hardware setup. Here the motherboard had developed a short for an (unfortunately) unknown reason, but the system was showing similar symptoms. I say similar because it came on, ran for one or two seconds and then shut itself off. That happened some short time after a high performance graphics card had been plugged in...

Just coming to my mind, I had another one, ASUS MoBo, that actually did exactly the same yours does. After several days of trying different BIOS settings and diagnostic procedures and starting to work a couple of times it finally never stopped looping/power cycling. In the end even in this case (it was a P68 chipset with an i7 2700K CPU) the MoBo turned out to be faulty. We replaced with a Gigabyte MoBo (no advert, just to let you know the changes...)with not exactly the same chipset (it was Z68 instead), but worked immediately without any further changes.

This does sound like an underpowered PSU. That being said, you need to replace it. Also, you should do no overclocking until you replace your current PSU. Overclocking draws more power from the PSU and puts more stress on your entire system (consumes more power and generates more heat).
