Sluggish performance and login errors

#1
I’m a member of the IT department in a relatively small company. Yesterday morning one of my users reported a strange error to me. I had never encountered this before. The problem he described is detailed further below. We have several of this model laptop; this is the first one to give us any problems.

System Information:
Lenovo ThinkPad T420s
Model #: 4170CTO
OS: Windows 7 Professional 6.1.7601 Service Pack 1 Build 7601 (64-bit)
Processor: Intel Core i5-2540M (CPU @ 2.60GHz, 2 Cores)
RAM: 8GB
Spec Sheet: https://docs.google.com/open?id=0B3zxmb_mQIFhV1V2dm5hZFNNazA

Problem:

  • The laptop locks up during normal usage, typically when running a Microsoft program such as Word or Excel. When this happens, it generally forces the program closed without saving any work done since the last save.
  • On 6/28/12 the computer forced a shut-down without warning. After rebooting, the machine gave an error message saying something along the lines of “Not enough resources” to load the user profile. The message requests logging on with a user account which has been used previously on the laptop, even though the account(s) being tried have all logged on before. In order to log in again the machine had to be rebooted several times.

The computer has yet to provide a blue screen error. I do have access to the Event Log, if it would be of any help. However, I could not find any errors associated with the log-on message we received. Here is one of the “Application Hang” errors, which I believe is what the user was referring to when he mentioned the trouble with programs.

To my knowledge, the computer has not given the login error since yesterday morning, but continues to run sluggishly and forcibly close some programs without warning. Earlier today I forced the pc to run an AntiVirus scan (we use ESET Smart Security), but it did not find any problems.
