I built a desktop computer with following components -
Intel i7-860 "Lynnfield" LGA 1156 processor with Thermaltake SpinQ heatsink fan, Asus P7P55D motherboard (vanilla), OCZ 8GB memory modules (2GB x 4), HIS HD Radeon 5850 graphics card, Antec 80plus 650W power supply, Mid-ATX case, Hitachi deskstar 1TB hard disk.
At first, I saw the POST but had to fiddle around with memory timings before I could get to installing Windows otherwise the system would reboot as soon as Windows DVD booted up. The whole thing stabilized and I installed Windows 7 x64 fresh copy. I installed all the latest drivers, ran memtest (no errors for as long as I ran it - 10 minutes?). I then went ahead and installed Metro 2033 game on it. The system was performing very well and giving me excellent results for about 7 days. It was also running quite cool (I continually was monitoring temperatures for everything inside).
One morning, I powered the machine on, and no POST, no display. I opened the case to see that CPU LED on the motherboard is lit solid (or very slightly blinking if carefully observed?). I reseated CPU, put thermal paste, used stock heatsink, removed RAM modules, tested MEMOK!, tested one module at a time, removed graphics card, removed hard disk, etc. but in vain. The CPU LED would glow solid red no matter what. No other LEDs lit on the motherboard except the green power LED.
I tested the system without putting any memory chips - still CPU LED would glow solid red. I did see some other people on the internet facing the same issue, but no one really found / posted the solution.
Later on, the behavior slightly changed and the system would boot up for a second, shut itself off, and repeat this cycle continually with CPU red LED on. That's when I stopped playing with it and rang up RMA support.
I have already sent the CPU and Motherboard for RMA (I hope they come back RMA'd because I feel that I saw one pin on the CPU socket very slightly out of order when I removed the CPU. Obviously the original problem occurred even before I removed CPU etc. so has nothing to do with the pin issue).
Any ideas? I am not ready to believe that Antec Power supply of 650W is faulty yet. It is a very trustworthy brand, but who knows. I also think that OCZ3G1600LV4GK RAM is compatible because it worked for almost 7 days without any issues at all.
