Computer Freezes after installing Vista SP1

Hello:

I have an HP computer that was running Vista nicely and smoothly. However, it appears after downloading and installing Vista SP 1, the computer has a tendency of "freezing" and the only remedy is to press the power button. I did notice that when the computer freezes, my second bay DVD drive flashes, and the activity light on the console, which indicates HD activity, constantly flashes.

It is a new HP Computer running Vista Premium Home. Any input would be great. This has caused me a lot of frustration and I am not sure of the remedy.

I have not yet received any feebacks on this problem, you may contact the free technical support from Microsoft there: https://support.microsoft.com/oas/default.aspx?ln=en-us&x=8&y=7&prid=11274&gprid=500921

Thank you for your response....I will try that out!

I had a similar problem, it turned out my memory had gone bad. I would advise running a memory check - there is one on the vista dvd.

Another possibility is a driver problem perhaps in the southbridge

I made a choice to reformat the HD, and revert to the original form of Vista. I am guessing I will have to wait to install SP1 until a later date. I appreciate that input though, and will be doing that memory check.

Thanks!
