Hello guys,

I'm here again asking for your help guys. My computer freezes in win7 and bios. Before this happened I was experiencing slow downs in my computer, pro longed loading times slow boot ups till this freezing happened. Here are my specs :

CPU - Core i7 2600k (not OC'ed)
RAM - Corsair Dominator 2x4GB
MOBO - Asus Sabertooth P67
GPU - Asus GTX 660ti
PSU - Seasonic 650w Gold
HDD - 2x Crucial 120gb | 2x 1tb WD blue
CPU COOLER - Corsair h80i
OS - Win7 Ultimate -

The computer is about 4yrs old. Whenever I leave it off and plugged overnight it freezes on cold boot in windows and bios. Yet if I unplug it and leave it overnight, I don't encounter problems on cold boot. Until this happened that it dont boot anymore. Sometimes the MOBO LED is stuck in CPU, sometimes in RAM and GPU. I don't hear any beeps. I noticed that after I leave it for some time it will start booting up again but still freezes.

I've tried replacing the PSU but to no avail. Made a reset in CMOS, reseated the CPU, GPU and RAM and still not working. I tried removing everything except the bare essentials, CPU, GPU, 1 SSD, 1 RAM and at that point it started to boot again. I slowly assembled it again and kept trying to power it on each part I put back in to find the culprit. It all went okay till I fully assembled it back again. Everything went smooth but after 2 days it occurred again! Boom! Freezes on cold boot! I'm starting to doubt that the motherboard is the culprit.

I hope some of you here can help me.

As much as I wanted to but I can't. I'm only using a laptop right now. I don't have any
spare computers I can test on. In my series of attempts I tried all 4 sticks one at a time
that it booted. All were seem fine. That's the least I can base on. Yet I noticed,
when there's only 1 stick of ram it boots fast. If I place one or more the boot delays about 1-2sec
after the CPU LED.
