Since purchasing my Lenovo X61 7675-CTO in December, I have had a similar problem with system freezes. My frustration with this problem cannot be understated, as this has cost me countless hours of work and this forum has not provided any solutions nor have I found any documentation of this issue on the lenovo.com/support. I live in Mozambique and sending the machine in for a replacement - what I would have done months ago - is out of the question.
I have recently located a solution on another forum. Here I will document a description of the problem, the solutions I attempted, and the solution that eventually (and imperfectly) resolves the issue.
Problem Description: The system frequently freezes (not BSODs), up to five times per day, requiring a hard reboot. The mouse remains responsive but no programs respond, and a CTRL-ALT-DEL produces no result. I hard reboot is the only option. This is a problem which has cost me countless hours of lost work and one entire day for a system restore, when the windows registry was corrupted beyond repair.
Solutions Attempted: I have read of similar problems with this machine on this and other forums.
1. I have read that many users have ordered a Windows XP disk for $50 from Lenovo and downgraded their systems. Unfortunately, I am living in Mozambique and obtaining these disks through the mail is out of the question. Besides, I did not purchase this computer to run a five-year-old OS.
2. First, I followed the recommendations for a similar problem (with BSODs) from a sticky topic on this forum, and upgraded the drivers for the Intel Turbo Memory Controller and the BIOS. I upgrade the former to v188.8.131.523, and the BIOS to v2.07. As of the date of this post, these are the most current drivers available on lenovo.com/support. This did not resolve the issue.
3. Following a post on Tech Support Forum, I disabled "Windows Hybrid Hard Disk Power Savings Mode" in the "Balanced" profile, and all other power profiles, for both "plugged in" and "battery." This did not resolve the issue.
Solution found: Following a recommendation on a post on TablePCReview, I disabled "ReadyBoost" and "ReadyDrive" in the "Intel Turbo Memory Console." This successfully resolved the system freeze problem.
Conclusion: The most current drivers for Intel Turbo Memory provided by Lenovo simply do not function for my laptop. I have to disable a valuable feature in order to use my machine, which I find frustrating. I hope that Intel and Lenovo techs will resolve this issue soon, and that a knowledgebase document will be published to facilitate other users (and there are, clearly, many) with this problem.

Check out these links for Vista performance on Thinkpads.
I wrote them so they are valid.

since you appear knowledgeable regarding this, are you aware of any problems having Windows Defender and macaffee security center enabled at the same time on my Lenovo T900 running Windows Vista?
