This has been a real headache for me since the number of freezes has increase from twice a week to about 1 or twice a day. The system just halts and nothing can be done but hitting the restart button. At the beginning I thought it was related to Flash since I was getting random freezes when playing full screen flash videos online. I also thought it could be the wireless pci card. But the system has freezed using browsing around GNOME.

The truth is, the freezes are really random and strange. I checked this thread Ubuntu keeps randomly freezing and try to ssh my computer using another one, but I could not ssh since it was really totally frozen. NumLock or CapsLock wasn't responding or blinking.

Since I could not ssh I, also ignored this article https://wiki.ubuntu.com/X/Troubleshooting/Freeze

According to my wife, the system has also halted under Win7 Pro 64bit but with less frequency.

Here is my system configuration

• Intel Core i7 2600k
• ASRock Z68 Extreme3 gen3 Motherboard
• Crucial M4 128GB CT128M4SSD2 SSD
• WD Caviar Green WD10EADS 1TB SATA II
• G.SKILL Ripjaws X Series 8GB (2 x 4GB) DDR2
• OCZ ModXStream 600W Power Supply
• Rosewill RNX-N300X PCI Wireless Adapter
• No external Graphics Card

I remove the Wireless card and used Ethernet to see if the problem was the that, but I got a freeze after doing that.

I also ran memtest86 and everything was ok.

The only other thing I might suspect of is the SSD. I will try to clone the SSD to a HDD to see if that solve the problem.

At this point I am stuck with the freezes.

Do anyone have a clue of why this is happening and how can i solve this?
