i know this is probably kind of basic but i couldnt find any info with search. i posted in technical support about some serious rebooting probs that have killed my system. a few people have recommended running Memtest86 to rule out my 512 Corsair stick as the culprit. i dl'd Memtest to a floppy at work and will try it tonight but im not sure how to run it. i looked on the Memtest site and the dont really give any instructions on how to load it/use it, its mostly what the errors may mean. can someone give me a real basic explanation of how to start it in Win XP.

much appreciated.

if i remember correctly, you need to use a program called 'rawrite' to write the program to a floppy disk and then boot from that disk.

Download it. Extract it from the .zip file. Run install.bat. It will create a bootable floppy for you. Boot off that floppy. Voila.

README.txt was too obvious?
3) Installation
===============
Memtest86 is a stand alone program that cannot be executed under windows and must
be loaded from a floppy disk.

To install Memtest86:
- Extract the files from the zip archive
- Open the directory where the files were extracted and click on "install.bat".
- The install program will prompt you for the floppy drive and also prompt you to
insert a blank floppy.
- To run Memtest86 leave the floppy in the drive and reboot.

NOTE: After the boot floppy has been created you will not be able to read the floppy
from windows. This is normal.

lol thorin. i dl'd it to a floppy but havent opened/looked at it yet. i assumed it was simply the program on it and that i needed to be in DOS to use it.

guess ill take a look at it :)

hmm, must be doing something wrong. i opened it, read the READ ME this time :) but when i click on the install icon i get a small black box (DOS prompt?) that flashes very quickly on screen. i never get prompted to put a new floppy in... any ideas?

yep, just type "cmd" from start --> run and navigate to the directory you uninstalled memtest86. Then type install.bat. Or you could use winimage to create a bootable floppy and then embed the memtest86 files.

thanks so much, got it. now if only i could figure out why my system reboots and reboots and reboots. if anyone is bored at work and hasnt been to the troubleshooting forum, here's a cut & paste of my prob... do you think its worth running Memtest?

starting Sunday night, my PC has flipped out and keeps rebooting and rebooting. here are the specs, its a self built:

P4 2.53 w/Alpha HS
Asus P4PE MB
512 Corsair XMS 3000 RAM
WD 80 GIG HD
WD 40 GIG HD
Hercules Radeon 9700
Turtle Beach Santa Cruz Sound Card
Antec True Power 480 W PS
5 panaflo/sunon case fans (so good cooling)

Running Win XP
and for whats its with a USB Hub and wireless Logitech Mouse and Keyboard


i did not receive an error, no bluescreen, just reboot. sometimes it would reboot during the reboot. sometimes it actually lets me log on and then will reboot within a few minutes while messing around on the net. it seems like it would only reboot when i would click on things - whether it was a new page in some forums trying to find a fix or a different option in ASUS probe or My Computer. i checked my temps in the bios, they seem fine. also checked them in ASUS probe before i crashed and seemed fine. i swapped out my PS and threw in a crappy EVER 300 W i had sitting around, immediately had the same rebooting prob before i couldn't even load windows.

i just tried hooking up my PC to a different PC area in the house that had a different outlet, surge protector and peripherals. no luck, same rebooting prob.

the only bit of info i received so far was an error message within windows that said the processor has detected a fatal error do you want to send report. i was finally able to go into system viewer and get these error messages as well: "Error Code 00000009C, parameter 1 00000000, parameter 2 8053f0f0, parameter 3 ccooooff, parameter 4 20040189." i also had a few "The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on volume C" as well as "A hardware failure reported by your CPU. This behavior occurs because your computer processor detected an unrecoverable hardware error and reported it to windows."

for some final info, i was overclocking slightly, very little to keep it rock stable, and the comp is only a few months old. of course i reset everything in the bios after the first few crashes/reboots and am running (err trying to run) at stock speed, same probs.

on monday night, i removed the HS and re-sat the p4 chip. applied some more arctic silver, put the heatsink back on. no luck same probs.

i also tried swapping in a 256 crucial RAM module i had in my other PC at home. no luck. reboot.

i ran a chkdsk on C this morning as this was recommended by windows in response to one of the above error messages, no luck immediately crashed to reboot. however, i was able to run the full chkdsk, reboot happened after i got into windows.

im at wits end here. all i can think of is that its my MB or my P4 processor.

cpu was 32-34. case around 42 i believe.

edit: checked them in bios and in ASUS probe.

edit take two: the reboots also happen right away. pc can be off for hours (overnight) and reboot happens within minutes. PC doesnt even have time to heat up really.

First thing I would do is disable the auto-reboot on error feature in Windows. If you right click on My Computer, go to advanced, it should be under one of the tabs, performance I believe. This way, you'll actually see the BSOD instead of XP just rebooting endlessly. This should help you narrow your search.

I would start by disabling unused devices in the BIOS; anything and everything other than onboard LAN and USB since you are using a wireless KB/mouse. You can even disable USB if you want to and attach the ps/2 adapters.

Then I would start yanking stuff; particularly sound cards. Also, remove and disconnect all drives that are non-essential to booting since it sounds like you are getting disc errors.

Since the problems seemed to have only appeared recently, it could very well be a corrupted HDD; I'm not totally up to speed on P4 platforms, but if you were OC'ing w/out changing your PCI dividers/locks, you could easily run into data corruption/HDD issues.

Somebody actually asked me to load this on a thumb drive for them! Sounds like a great idea! (to test systems which support USB boot--and I have one that I may get some time to try)

Try something simple. Disconnect the Power Switch lead from your motherboard. Start the system by momentarily shorting across those two pins on the board. I find a phillips screwdriver works well.

I had a system doing similar things and it was a bad switch on the case. The error messages in Windows may be bogus 'cause it's going ape-sh*t trying to boot up.
