Hi,

I have recently updated my Motherboard/CPU/RAM. It was running fine until two days ago and now it started to crash and stopped running after bios beep sound (but does not get to bios screen with F2 or Delete)

After doing little bit of testing around, I noticed that running with 2 RAM will boot the machine. So I thought its bad RAM, so tried to run the machine with each RAM at a time and it seemed to work fine. (Although even with 2 RAM, opening any kind of application (including chrome)) would terminate Windows.

I thought may be its a bad MB, so I tried to place a working RAM on each slot one by one and seem to run fine.

OK if 4 RAM does not work, and 2 RAM works, it must be Power supply, so I went ahead and bought new power supply and it did not improve the situation. (Although 4 RAM does not run, I can run chrome and do majority of the task except couple application including CrystalDiskInfo)

Ever since I had this issue, even with somewhat working 2 RAM, the CPU fan is blasting loud at the maximum setting even though CPU temp is around 30C and initial boot does not throws CPU Fan Speed Error. (I do not over clock)

I am starting to run out of option. Is this Motherboard issue all together?

Here are the specs of my machine. Let me know if I am missing.

Thanks in advance.

memtest86 definitely takes really long time... 6 hours and still not done.
As I had to sleep and my machine was right next to me, I had to turn it off but is this normal?
