Random pc problems help

[blakmumba]

Hi all, I've got an i7 920 running at stock speed on an asus rampage II motherboard. Now I don't know wether my motherboard is failing or my processor. My hard drives randomly disconnect forcing a reboot, my cpu temp is gradually rising each and everyday just sitting on idle despite all fans (Level 10 GT LCS) on full or the whole computer freezes and once rebooting I have to re-install windows because the files have been corrupted. I have just started to get BSOD e1 error. At times the pc runs flawlessly and at times runs like a snail.

I have changed sata cables, re-applied thermal paste, re-installed windows etc etc but to no avail. So now the only thing I could think of its either the motherboard itself or the cpu.

Please could someone help or advice as this would be much appreciated.

With the widespread problems your having I'd say the motherboard is junk. Can you RMA it that would be the first thing I would do. Do you get a POST beep when it starts? Have you tried updating the bios?
