Windows 7 64bit freeze problem on DZ77RE-75K + 520SSD

[Wenhao_Z_Intel]

I am using a new desktop with DZ77RE-75K board. OS is Windows 7 64bit Enterprise. I am annoyed by endless freeze problem.

The detailed device list:

CPU: 3770K

DZ77RE-75K

240G Intel 520 series SSD + 2x Seagate Barracuda 2T

2x 8G 1600 memory

The freeze happens without any sign, when i browse the web or start an app. The mouse and keyboard lose response suddenly and i have to turn off the power manually and get an unexpected system power down. It seems that the problem happens more when i start uploading something to the web, but not every time. I also noticed everything on this new desktop works a bit slowly than other normal machines.

I have tried the following solutions as I know,

1. Rebuild the OS (many times)

2. Update all the drivers to the latest ones and the Bios is also updated

3. Check the connective bus of all the had disks

but it still freezes...

I use the default Bios setting. Should i change something in Bios?

This made me so crazy... Can somebody help me? Thanks in advance.

I'm sure that there is a problem with ram setting, have you already loaded xmp profile? Please le me know the brand and model of your ram kit.

Thanks！

My memory is Corsair Vengeance DDR3 1600 8GB (CMZ8GX3M1A1600C10) and i have two same mem inserted in slot 1# and 3# . The detailed info is shown in the figures:

I didn't load xmp profile in the bios. Actually, I do not changing any settings in the bios. All are default.

Should i enable the xmp profile?

Thank you again!

ok, try to install your kit in slot 2 and 4 and then go to bios and load xmp profile, it should work.

[Wenhao_Z_Intel]

OK！I will try it. Hope it works.

It just froze twice in one hour...

Thank you anyway. Any other suggestions?

Hello QMark,

In order to find out which device is causing the problem we would need to troubleshoot the system with minimum configuration and out of the chassis to discard any grounding issue.

But first, let me know the following information:

• Which hard drive are you using to install the OS?
• Which SATA mode did you chose, IDE/AHCI/RAID?

Regards.

[Wenhao_Z_Intel]

Thank you for reply, Sylvia.

I have 3 hard drives, one intel 520 SSD and two HDDs. All of them are new. The OS is installed on the SSD and the sata mode in Bios is AHCI.

I have checked the following things:

1. different memory slot. no help

2. different SATA port, power cable and data cable for the SSD. no help

next i will try

1. use another set of memory model

2. keep the SSD only and remove two HDDs to see if the hybrid hard drive has problem

Do you think what should also be checked?

Please try another set of memory model, on my dz77ga-70k I have installed 2x4G 1600C9 corsair dominator platinum and they work perfectly also the vegeance 1600 low voltage work fine for sure.

[Wenhao_Z_Intel]

OK. I will try.

Actually, I also have another desktop with DZ77GA-70K + 520 Intel SSD + 4x4G Kingston 1600, which works well. It seems I need do some cross-checks during the weekend.

The freeze issue was figured out. It was caused by an outdated PCI wireless card. I unplugged it and everything looks ok now.

Kindness help from Tadashi and Sylvia is greatly appreciated! Thank you!
