Random system hang/freezing

I'm getting random system hangs and I am hoping someone can hep me identify the cause. The system completely locks, and is not the result of any one action (can happen at idle)

I have attached the SF Diag results.

System specs

Gigabyte UD5H Z77 Motherbaord
i5 3570K
CORSAIR Vengeance LP 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model CML16GX3M2A1600C10
SAMSUNG 830 Series MZ-7PC064B/WW 2.5" 64GB SSD
Geforce GTX 660TI

Welcome to SevenForums.

Are you getting any blue screens? Because there are no dumps in the attachment.

We need the small memory dumps. > Dump Files - Configure Windows to Create on BSOD

You mention a SSD,

Update to that latest firmware for it.

Daemon Tools,

Please uninstall DAEMON Tools. It uses a driver called sptd.sys which is known to cause BSODs in Windows 7. Uninstall the software using Add/Remove Programs. Reboot the system. Once the program is uninstalled, run sptd.sys uninstaller to remove the driver from your system.

As an alternative, many people recommend the use of Total Mounter or Magic ISO

1. Is this a new computer?
2. How does it act in Safe Mode?

16GB of ram, are they having the same clock/speeds etc?

Can you explain the lock ups in detail?:)

I see. You may want to re-seat the RAM, SATA & Power cables and graphic card.
Clean up dust (If there is any) :)

Seems weird.

Anyway, do the following:

Run these tools and delete anything they may find:

• Anti-rootkit utility TDSSKiller

ESET online scanner:

• Free Online Virus Scanner | ESET

Update the firmware of all the SSD's you have.

Run the System File Checker that scans the of all protected Windows 7 system files and replaces incorrect corrupted, changed/modified, or damaged versions with the correct versions if possible:

• Click on the
• Type CMD on Search
• Left click and Run as Administrator
• Type SFC /scannow

Full tutorial here:

• SFC /SCANNOW Command - System File Checker

Run Disk Check on your hard disk for file system errors and bad sectors on it:

• Disk Check

Upload of all your hard drive(s) using crystal disk info and "Summary" Tab of speccy:

• Speccy - System Information - Free Download

Look for an update the audio drivers:

Code:

Driver	c:\windows\system32\drivers\tcnearaudio.sys (3.5.3.8786, 37.97 KB (38,880 bytes), 8/30/2010 1:44 PM)

Update networking drivers as well. (Search for in google.)

Make a full scan with Malware bytes and Microsoft security essentials.

Hope this helps for now.
