Earlier today, i asked a question about my computer turning off automatically. well someone suggested getting a new psu and it worked....until my computer went into an infinite boot loop. Now i have no idea what the problem is.
Specs
CPU: intel core i5-3570k
Graphics Card: Geforce GtX 650 1024mb
Ram: x2 Corsair Vengeance LP 8gb
x2 Kingston 8gb
Motherboard: MSI z77a-g45 military class 3
PSU: Thermaltake TR2 700watt
What usually causes infinite boot loops like these?
 
Solution
Look around the edges of the motherboard and make sure nothing is shorting the motherboard to the case (no loose screws ect.). Re-seat the RAM (clean the contacts and blow out the RAM slots). Then try booting the system. If it is still doing the reboot loop, pop out the battery to clear the CMOS. Leave the battery out for 10 minutes or so. then reinstall the battery , and try booting the system again.

If nothing has helped, I would consider bread boarding the motherboard.
For a system using a single GeForce GTX 650 graphics card NVIDIA specifies a minimum of a 400 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 20 Amps or greater and that has at least one 6-pin PCI Express supplementary power connector.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) is the most critical factor.

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

Why do you keep buying poor quality PSUs?

Defective memory modules or defective graphics card or dead CMOS battery can cause infinite boot loops.

Try removing the graphic card and just use the integrated graphics until you determine if the problem is the memory or CMOS battery or motherboard.

Try connecting a POST beep speaker to the JFP2 Speaker pins to determine if there are any beep codes being produced that may give you a clue as to what is causing the problem.

What's happening is the computer turns on for 5-6 seconds then turns off, and the. back on over and over again until i manually stop it. i've tried resetting cmos and i'm currently running it with just the cpu, motherboad, and psu connected. its not the psu, and i fear it may be the cpu or the connecters.

these psu's are the most i can afford at the moment. and i tried running it without the graphics card and it still did the same thing. i tried replacing the cmos battery with two different ones and the same thing happens, i tried using each memory stick seperately, same thing. it shouldnt be the motherboard or the memory. im at a loss right now and i realy want to find a solution soon.
