Today I tried to install an Z77 mobo and an i5 3570k in my very old cheap pc case using the old 550w psu which still works with an old AMD X2 64 dual core system (which I'm currently booted into but is currently placed on the outside of my pc case as the new one is still installed).
After I made sure I connected all things I powered up the system BUT it would not post anything on the screen (with intel gfx or gtx 570 card). The cpu led lit a solid red, my Zalman cnps10x optima heatsink fan did spin up and the green sb power was lit solid but everything would then power down, red led turn off and AUTOMATICALLY power itself back on then turn off again and it repeated this until I switched of the main power on the psu. I have since not been able to even turn on and replicate this as everytime I try and power on the system now the fans and red led do not power on at all but the green sb power led is always lit. Now, I have big mobo power connected properly but I only have a 6-pin power connector along with a small 4-pin power connector coming from the psu so I have tried to just use the 6-pin first then the 4-pin in the 8-pin power socket (for the cpu itself iirc) on the mobo. However in the past I had a sandybridge cpu installed in an asus z68 board in the same pc case and managed to use the 6-pin with it ok for a few months so I'm thinking maybe it's not that I need an 8-pin with my new Z77 board. I also connected one of the black 6-pin connectors (molex to 6-pin) for the gfx to the cpu 8-pin socket in the mobo but still no luck (I do know that the gfx 6-pin has one hole missing as usual so perhaps it wouldn't work anyway but I wanted to try).
Just to let you know as I cannot get my new system to work I have had to put my old asus/AMD mobo on the side of my pc case and plug everything from the psu back into that so that I can continue using the computer and as you can see it powers on ok as I'm writing this!
My previous Z68/i7 was bought as a combo on ebay with the cpu already installed so today was the first time installing a cpu (the i5 3570k) for me but I made sure I did it correctly as they are not cheap! I attached the backplate, applied thermal paste to the cpu and attached the heatsink ok but after putting in the cpu and pulling the lever down to secure it I found it incredibly tight so much I thought it might be damaging the sides when it touches the cpu but it eventually got locked down but I didn't expect it to be that tight, is this normal?
I will probably get a new case soon as well as a good psu from xfx or antec so that should make a difference if I can't get it to work as it currently is.
Sorry long post, but it needs explaining as much as possible. No mention of troubleshooting in the mobo manual but it appears the cpu led lights up when there is a problem with the cpu so I would love some advice please.
