I have the same problem, only it doesn't occur each time I boot. It happens maybe half the time. The system stalls on the Win 98 clouds screen, but it isn't locked up, because the little shades of blue at the bottom of the screen continue to move. I've tried skipping driver loads and ini files, but, since the problem doesn't happen every time, I'm never sure if it actually eliminated the problem so I can narrow my search.<br><br>I have tried choosing the "Create boot log" option, but when I do and the system stalls, after rebooting into DOS mode, I can't find the <FONT FACE=monospace>bootlog.txt</font> file. Screwy, huh?<br><br>Additionally, every so often I get the "This program has performed an illegal operation and will be terminated" error for <i>explorer</i>. I also get the occasional blue screen of death for various <FONT FACE=monospace>vxd</font> files.<br><br>I believe I have some kind of fundamental corruption or configuration issue here, but I cannot reliably duplicate the symptoms in order to effectively diagnose the problem.<br><br>My system is homemade, with a 450 MHz AMD K6-2, 128 MB of PC100 SDRAM, 3dfx Voodoo3 3000 graphics accelerator, Tyan Trinity 100AT (S1590S) motherboard, pickles, onion on a sesame seed bun.<br><br>The BIOS is one generation behind the latest available, but, according to Tyan's web site, the last change was only to accommodate huge hard drives, which doesn't affect me. I also believe I have the CPU voltage set correctly.<br><br>Is there a utility that can exercise (or ex<i>or</i>cise, for that matter) my system to help me find the culprit(s)?
