Basically, seemingly out of the blue my computer has begun to hang during boot up at the verifying DMI pool data step. First, let me explain the last time I was able to use my computer. My computer had been running for quite a long time because I usually don't shut it down. One day this week when I got home, I logged in and noticed that the computer audio wasn't working. I made sure my speakers were fine (they were) and also looked at volume controls to make sure everything was good there also. When these two things didn't fix the problem, I thought that this could be due to a stopped driver so I went into device manager and disabled the driver and then enabled it again. At this point, I restarted my machine and since that time I cannot get my computer to boot up without stopping at verifying DMI pool data.
I am trying to solve this issue methodically and I have done a few things already. I ran memory tests and memory should be fine, I reset the CMOS and also took out the CMOS battery to see if it was still good. The voltage meter I used indicated that the battery still has 2.94 volts so that should be fine as well since the battery is 3 volts nominally.
I am trying to figure out what to do next. I would like to do everything I can at the software level first before I go ahead and start replacing hardware. I find the audio problem to be peculiar since it happened at the time it did, but I'm not sure that this is the cause. Also my sound card is integrated into my motherboard.
Please respond with your suggestions of what to do next. Also I'm trying to understand what role verifying DMI pool data has during boot up.
ps Operating System is Windows XP 64 bit
