Hello, I have a computer that I can not get to stop rebooting. I originally took the system and reformatted and reloaded the OS. This did not fix the problem. I then decided that it was a bad motherboard, I replaced that and it still did the same thing. I then formatted and reinstalled again from another cd and it still does it. I rule out an overheating issue as this machine will do this on power up after being off overnight. I thought well maybe the power supply is bad, but guess what I can boot into safe mode and no problems. I am very aware of windows drivers and the fact that it would seem to be a corrupt install but as stated I have totally fdisked and formatted each time. I have even used an old low level formatter that has always worked before still the same results. Thanks for your help.

Remove all the cards from computer except video card then reboot. if this work, then it must one of cards you just removed. if it does, try a different video card.

by kevinj

This MOBO is all integrated, It did have a modem card but I have removed it, still same thing. Thanks for your reply.

Besides removing all cards,check to make sure that you donot have a virus on the system
Then to check the power management setup,disable in control panel and see if the system will boot properly

by kevinj

Thanks for your reply, your suggeestion does not make sense to me, If I have changed MOBO and wiped the drive can a virus still exist? If so how to run a virus scan on a blank drive?

What type of computer do you have? We have had this problem with Dell laptops and it did not seem to matter what OS we were using. The problem was rectified by updating the BIOS.

by kevinj

It is a Micron PC RS2105 with a GRC DR742E MOBO. I have obtained all bios updates and still no good. I have started from th original and finished at the latest and still no luck. Granted I only tried this on the original MOBO. I have not tried it with the new MOBO as of yet.

hello....boot in safe mode and change your display adapter to a vga standard...remove the other cards to avoid posible conflicts.
boot in normal mode and tell me what happens
...good luck

First, at no point did you indicate what operating system you are using. This could be vital data since various operating systems distribute different problems. Now taking a guess.. if you are running Windows 2000, then you need to disable the automatic reboot option. You do this by right clicking on My Computer on your desktop. Click on the Advanced tab. Click on Startup and Recovery. Unclick the Automatic Reboot checkbox. Hopefully this solves your problem. If not, then please let us know exactly what OS and the make of your computer you are using.

by kevinj

It is Win98se, and I have done this to at least a couple hundred various computers and have never had this happen to the point that I could not get it by reloading the OS from two different cd's. I will try to load 95 or win nt to see if same results. Thanks

If you can boot into safe mode and it doesn't reboot, then it sounds like something that's loading automatically is causing the reboot. Go into safe mode and check all startup files and programs. Autoexec.bat, Config.sys, and go into msconfig for W98 to see anything else that loads. If it's a different OS, go into the registry and search for RunOnce. See if anything is loading there that doesn't need to be. Make sure that there are no command lines listed that would prompt a shut down in any program desktop shortcuts by looking at their properties from the context menus, making sure they all point to the proper program. Good luck.

by kevinj

Very good, I am aware of the startup files and their role, and I have fixed and troubleshooted many pc with similar problems but this one is more than I have seen. It just doesnt make sense, If I format and reload the OS it should be fine. Or it hasin the past, maybe I have been kucky up until now I dont know for sure but its not a regular problem, it is deeper than it seems.
Thanks anyway

by tamj123

One more suggestion, I think you have changed all the hardware except two thing: memory and CPU. Try change these two items two.

by kevinj

Can you believe that I have done this as well with the same results. I thank you for your answer

by ojmj

Do a step-by-step reboot.

When you get to the offending file, the computer will reboot and you will know where the problem is.

Do you have a scanner or other peripheral hardware attached? I've experienced reboot problems with CD-RW drivesand scanners.

O.J.

by kevinj

The pc will reboot after all these files are ran. It seems to reboot right about the time the desktop is loading. Thanks for the reply.

BOOT INTO SAFE MODE AND:
CHANGE VIDEO DRIVER TO VGA STANDART
REMOVE MODEM, NIC CARD AND EVERY OTHER DRIVER INSTALLED.
REMOVE CDROM CABLE AND FDD CABLE
LET THE SYSTEM BOOT AND ANSWER NO TO EVERY ATTEMPT TO LOAD A DIFFERENT DRIVER.
IF THE SYSTEM CAN BOOT, START LOADING DRIVER BY DRIVER, INSTALL CARD BY CARD UP TO COMPLETE THE INSTALATION.

hOPE IT HELPS

Seems to me that you have a bad CDROM.

In safe mode, Windows wouldn't load the device driver of CDROM and therefore wouldn't try to even recognize the CDROM you have.

Whenever you load Windows in Normal mode, some communication occured, and that somehow send Windows the wrong signal to reboot.

Try to disconnect CDROM.

Ok Kevin, let's try to work it out.
it could be hardware or software problem, so let's workaround and find out what exactly is.
Can you please disable all the features on bord such as Sound Card, modem and everything, just leave video, once more format the whole thing, Install Windows 98SE plain, no further software, only Windows, and leave it that way. Wait for it to restart on its own, if it doesn't reboot let's enable the Sound card, one device at the time, install the drivers, and let's do the same, let's wait for it to reset, if it doesn't then keep going with the next devices, if at this point you already got problems then you must be able right now to know where was the problem (hardware and you know what device was the one givingyou problems).
Please e-mail me if it doesn't work.
Good luck,

@lberto

I have seen this problem about 4 times over the past few years..

Power off the machine..
Swap out the memory..

I bet that fixes it.

Let me know.. kay?

Buy a normal rubber and a brush.
Rub the RAM pin and the processor pin and brush it away.

Then use the brush to brush the ram dimm and processor hole or slot, even all your pci slot on the motherboard and VGA and Sound card. all of it. clean it

If still the same problem..

install your mother board chipset..
Via or Intel chipset?

If intel,, go to www.intel.com
If via, go to www.viahardware.com

After that, install your vga card (Hope it is not S3 virge).
Then install directx 8.0a

Try it.ok?? Hope is works

by kevinj

I dont know for sure if that wouyld help considering there are now cards in the machine and the motherboard has been replaced with anew one. It is a good idea though and I agree but this would not apply here, Thanks for your reply.

by kevinj

Thanks for all of you replies as they have been very informative. I have changed every component in this machine and I still get the same action. I was mislead in thinking that the machine stayed up in safe mode however, I thought it was then I loaded WIN ME last night and it rebooted on me in safe mode, I dont believe it did this in 98. It has been a very frustrating problem for me and It has to be the CPU, thats the only component left in the system. I have never experienced a cpu problem if this sounds like it to someone please reply with your experiences. Thanks again for all of your assistance.

re: my reply above. I didn't mean the power supply. I meant the switches on the case which turn on and off the machine and, if there's one installed, the reset switch.
If the reset switch or the power switch are faulty and activate then the machinewill power down.

by kevinj

I have replaced the power supply and place all the hardware in another known good case, still the same thing Thanks for your replay

by thecomputerguy74

I think you have answered your own question. From everything that you have said that you have tried, the only things left that I would think of are the CPU or MB. Good Luck.

by kevinj

At times yes, other times no. I have tried loading 95,98,me,2000 and NT with the same results. If it gets through the install it reboots as soon as it hits the desktop. I dont know what to try next, I have repalced every component and it still gives me this behavior. the only thing that has remained is the model of motherboard, sonce I have replaced it as well. Thanks

by vh_s

Kevin,

I experience the same thing now. MB is Intel VX (old one) with 233 from Cyrix (PR233).

After some serious investigation, apparently the rebooting is caused by a combination of MB (+its processor) with Seagate harddisk (1.7Gb, also an old one).

Yet, when I switched the harddisk to a Western Digital, the problem disappear. Windows 98 SE could start normally. Putting back Seagate causing rebooting to repeat. The moment of rebooting happened when Windows tried to switch from text mode (startup) to the graphics mode.

Similar to your case, putting Windows in safe mode would allow Windows to start normally.

Want to try ? Keep me posted, okay..

I have cycled in 4 different brands of hdd thinking something sin=miliar, and if the os loads it reboots, at times it is a minute or so after the desktop is loaded. And it does not stay running in safe mode either as I thought earlier. It will reboot at the dos prompt as well. Thanks for your reply, and the feedback. The only thing I can think now is that the mobo is proprietary in some way. As I have a new mobo and all the other components are new as well, mobo, hdd, fd, cd-rom drive, case, memory and power supply and it still does the same thing.
For example if You have a factory Compaq with a modem for example, you can replace the modem but the modem will not work in another brand of machine. I think this may be the problem, its all thats left. Any ideas please hit me back on this. Thanks again

by dmiles

If the CPU has overheated,then it will cause the system to reboot,there are also timing jumpers on the MB,that could be interferring with the hard drive and CPU,causing the sytem to perform in thisn manner
Sometimes when you think the virus is goneit may have attached it self to the MBR.

by kevinj

I have changed mobo, cpu with thermal protection applied, hard drives, reformatted, low level with utilities and reloaded and it still is going on, Thanks for the continued ideas, Im not one to be beat easily but his one is beyond me,

Thanks

Hey this answer is a liitle off the wall and please dont take any offense to it, its not meant as an insult to you. But if you've changed out every piece of hardware and tired to install 3 OS's its not a computer problem, its probley you...try this totally disassemble the computer, take a day or 2 away from it, and in fact all problematic computers. Call up a friend, buy a beer have him (or her) come over and build the computer install the OS and see what happens. Im only saying this becuase sometimes it helps me, I get frustrated and stuck in the actions over and over, somtimes it helps to take a break and watch someone else work on a problem. I hope it helps
