OK, guys and gals, riddle me this.
I repeatedly get the same three errors -- although in no particular sequences, and I get some more regular than others.
Problem 1: BSoD with error code. The code is 0x00000070 (The other parameters are all zeros.) I searched 0x00000070, and I could only find it associated with a Windows 2000 error tied to "SESSION4_INITIALIZATION_FAILURE." (I am running Windows XP Pro, not Windows 2000.)
Problem 2: This one happens most consistently, except for when I have problem 1. When I boot, I first encounter a BSoD without an error code. The screen simply says something to the effect that my computer has stopped because of a hardware problem and that I should contact my vendor. (Yeah, right.) When I reboot following that screen, I usually get the apolgoy for having crashed and urging to choose one of a half dozen ways to book. I choose the one to book using the settings from the last normal boot. The real last normal book was probably last year sometime, but still it works. Except for the times it doesn't. After this, when I boot again, I'll get the same error codeless blue screen and the endless tale starts again.
Problem 3: About once a day, my computer doesn't make it through the complete boot. (At least that's my guess as to what happening) During the boot sequence, I'm left with wallpaper and a pointer. The only way I can do any work is to hit Ctrl+Alt+Del to bring up Task Manager, and then use "New Task" to run PowerDesk 6, which has a launch bar I use to run my programs. As best as I can tell no applications or utilites run unless I launch them manually.
FYI: I have a Dell 8400 P4 with 2 megs RAM, four hard drives -- two as a RAID 0 and 2 as RAID 1 I know I could reformat and reinstall, but I'm or a deadline and don't want to do that.
