Hi, brand new system, lots of stop errors. I had installed XP several times, always got random restarts which were actually stop errors once I unchecked auto-restart on failure. Even had some sort of errors (not usually stop error) sometimes while installing XP. Anyway, these seemed to happen fairly randomly, I couldn't trigger it if I wanted to. I usually got 50 and 8e I believe. Also I had a lot of "this program has caused an error, send error report/do not send", not sure if that is related. Anyways I clean installed XP and found out I never installed motherboard drivers after my previous install. I did this as well as installed the USB driver, which I also never did. I thought this would fix the problem. But I was typing in Word and received a 0x0000004E error. Restarted, and received the same error even before my anti-virus showed up in the taskbar. Restarted, now typing this post. System details are: antec case mid power plus 660 amg MB ASUS P4T533-C 850E/ICH2 INTEL RT ATI|RADEON 9700 PRO 128MB TV/DVI 8X CPU P4/2.4BGHz 533M 478PIN/512K % RAMBUS RIMM 256M|1066MHZ -KINGSTON% HD 80GB|WD 7200RPM WD800BB % *CDRW 40X12X48|LITE ON LTR40125S% DVD|TOSHIBA 16X SD-M1612 OEM % CPU FAN INTEL| BB P4 VOLCANO 478 RT -- ANY help would be GREATLY appreciated with this matter. Thanks a lot.

Remove the RAM and try another stick of RAM if you have it.

i'm having this problem now...i have gone through half a dozen ram chips, that aint it. I"m sure it has something to do with ACPI now i read a random report about how to turn off ACPI when it ask's you on the install to hit f8 if you have any scsi disk adapters. hit f7 to silently turn it off. I havnt tried it yet but i might. it's annoying.

It could be the RAM, but also maybe not? I tried running this program Memtest at http://hcidesign.com/memtest/ and it said I did have errors. If you have faulty RAM, does the computer work? Is all the RAM detected? Also, i've gotten now lots of different types of stop errors, and sometimes even after a reboot I'll come back and see one. Bakka, yeah I've read stuff about ACPI but I've heard you should change it to Standard PC and then I've also heard that's a horrible idea. So I have no clue on that one. One thing that I want to try is disabling shadowing or caching of my BIOS. But I don't know how to do this. Then the other day I read something about DMA. Also I have a Western Digital caching hard drive, maybe that's something. I also have the new Radeon, could that be a cause. I'm pretty frustrated with all this, I wish someone could just tell me what's wrong. Bakka, what exactly are you supposed to do for F7? Thanks.

I have that tech doc at home on my fav's i think, but heres what i did, i did a search in google for ACPI errors. on one of the tech pages i read it mentioned about how to turn off the Acpi. I just got a XP pro cd *finaly* so i will be testing this f7 theory more in the coming weekend or sooner. i'll post it under a new acpi heading, watch for it. what i do gnow is that, i work as a tech in houston, i install xp alot...and it happens on win2k too, but the acpi seems to be a vary big, and quite problem. Currently it's my number one pet peve and source of most of my XP related problems. Microsoft mearly acknogis the problem *(sorry for my spelling)* but gives no fix pushing the problem off on YOUR bios vender. more research to come bakka king of the wicker people

Yeah please let me know about how your F7 thing goes. I mean I've read things pro and con ACPI. You can change it under device manager but I tried that and things got real crazy. Interesting. I called my support today and here's what they had to say-- ACPI is WinXP, it shouldn't be related to stop errors who knows what that means. i do know that my friends with dells have their device manager say ACPI right now. DMA is DVD? They just glossed over this. They said to run a hard disk diagnostic since it is related to virtual memory. I'm doing that, I did the quick test already and it said it was fine, I'll run the full test later. So I think it's my memory. I don't know if a computer runs fine with faulty memory and then messes up all of a sudden, but maybe? Weird

Another quick test would be to stick your hard drive in another pc and see what happens. If you are still getting stop messages, then you may have some bad sectors on your hard drive. Try to think simple before getting complex.
