My computer freezes for about 30 seconds, this happens occasionally. When it happens I can still move the mouse, sometimes even alternate between tabs in google chrome. If I try to open windows explorer nothing happens. Also chrome rapports "waiting for cache". It also happens in starcraft II, during which the sounds loops.

I have made a Trace as this topic describes: How do I troubleshoot a Windows 7 freeze or slowness?

Trace: https://docs.google.com/open?id=0B_VkKdh535p6NklhSDdBLURUMnc

I have looked at it, but I couldn't figure it out.

My system specs are:

• AMD Athlon X4 651
• Asus Ati HD6670
• ADATA SSD sp900
• Asus f1a55 mainboard
• 4 GB crucial 1333 ram
• 500 watt atx ps

I'm running Windows 7, fully updated.

Any help is much appreciated.

Update:

I tried something before your reply that may have helped the problem. I don't know for sure if it has, it's too soon to tell.

A bit of history first. I had problems installing win7 on my ssd from the start. In IDE mode it worked, but I had the same problems as above. AHCI was a total fail, with it on before install as well as turning it on after install (including tweaking register). I didn't bother installing the AMD chipset/AHCI as it was reported to have no TRIM function and thus make problems worse.

Eventually I did install the AMD SMbus driver as the stability issues were driving me crazy. It worked, no more issues, until I installed some extra drivers and software. Audio/LAN/ASUS suite, I don’t see the relation, but somehow it screwed up my system again. As a last effort I posted here on this site. After which the thought occurred to me turn on AHCI again as by now I had all necessary drivers installed anyway. (plus all windows updates downloaded/installed in the meantime)

I did and stability didn’t seem great the first few reboots, but eventually everything seemed to work great. I tried to play starcraft II – an almost guaranteed freeze before – and I had no problems. I’m basically crossing my fingers and hope the problem is gone for good.

I still think it has something to do with my SSD. In my research into the problem I noticed a lot of these issues with sandforce 2281 firmware, the exact same firmware I have. People reported the same problem that I had, freezes. Additionally they reported that during a freeze the hdd light stayed on, I noticed after I read this that this happened with my computer as well. None of this is conclusive evidence that my SSD is really to fault, but it is suspicious.

And why turning on AHCI would fix it I don’t know.

Thank you Tom for taking a look, if the problem returns I will certainly do what you advised.
