First of all, I'm new to this forum, so apologies for anything I might post incorrectly, and much gratitude for the help! After an endless series of BSOD's, mostly 0X0000008E, but then a slew of others. I have done the following: Replaced my main hard drive Reinstalled Windows XP SP# and run ALL the updates Ran BOTH Memtest and Windiag several iterations, which showed no memory errors. Reinstalled my antivirus (Kaspersky) and ran ALL the updates, including the upgrade to 2013. Everything was going OK after the last re-install (I've done this three times now!), and then I noticed that I had no sound. A ran the Soundblaster diagnostic on the soundcard and got a consistent "FAIL". At that point I created a "last good" restore point because everything was working, booting, shutting down, rebooting fine. I took the sound card out and reinstalled it to make sure everything was in place (having shut down the machine of course), and immediately started getting BSOD's (0X0000008E, 0XC0000005,0X00040001,0XA9BCB728,0X00000000) Tried to go back to the last good restore point, having removed the sound card. No go. Went back to the restore point before that. No go. I ran Everest and saved a report. Ran chkdsk, even on the new drive and it was OK So I'm going to try to upload some zipped minidumps and the Everest txt file. I really appreciate any help you can give me here. Thanks and again my apologies if I missed something. All the system details are in the Everest report, so I won't waste space re-posting.
