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.

It's warm at the moment (assuming UK) but it shouldn't be enough to bother a stock CPU at idle. My 3750K at 4.3GHz with a Noctua NH-D14 has barely twitched, and the fans are still down at 800 rpm.

I'd try to completely rule out a cooling problem before blaming anything else. Have you got a different cooler you could stick on for testing, even Intel's OEM cooler would do?

Yep in UK. At stock the temp is at 40/41c. I've tried a different case (Silverstone TJ10) with the H50 in push/pull config yet same prob.

what ports are you using for your hdd?

if you have the marvell ports on that port they are well known to be poor,stick to the intel sata ports

Hi, I'm running intel ports.

what memory and how much are you using? id look at that next and look at how much dram/vtt is being used in the bios

I'm running corsair xms3 classic 6gb (3x2gb). QPI/Dram is at 1.38v (auto)
