Computer reboots at startup

Works in safe mode but not normal mode.  May be some form of startup program or driver that's causing your system to crash... I would try updating drivers for all your devices.. audio, video and mainboard.  Give that a shot frst.

there are somekind of problems initialising your internet connection:
you can't get an ip leasing ,there are some processes which avoide to start and your pc tries to act like a server-are you aware of this fact?
do you use your desktop pc as webserver /fileserver?
Why are the performance counters enabled on your system?

If you can access the desktop under safe mode try to make all scans with updated antivirus software like:Antivir personal edition,AVG
scan for spyware and troyans! :stinger,spysweeper,spybot S&D,ad-aware,winpatrol,
pestpatrol:http://www.majorgeeks.com/download1187.html - but please update it
i'm not sure but i think your system will crash down even if you enable the internet access under safe mode,,,
try also with msconfig todisable all NON microsoft processes and all startup entries and check out for changes,,,
if you use a net card swap it with another goodworking one,,,
make a simple resume about your internet connection:type of net access device,driver installation update,internet connection settings,do you even use dhcp ?
disable also netbios over tcp/ip in your net setting,do you use any kind of desktop firewall?

mwnni:
Thank you for all the resources - I have read all but am not sure I understand them.  I do not know why I have proformance counters enabled.  My system is not used as a server, though I do have a wireless LYNKSYS router attached and use it so my other computer can use my dsl and printer sharing.  My system does not crash when I start in Safe mode with internet access. I do not know what dhcp is and dont think I use it.  I use tcp/ip but not netbios. I use Norton's Internet Security firewall. I have disabled all unnecessary startup items using Startup Mechanic 2.2.  I use SpyBot S&D and it says I have no praisites, spyware, or adware.  My system is virus free using up to date Norton's AntiVirus software..

nobus:
Taking your advice I unchecked automatic restart and reeived this error message:
stop: 0x00000000, 0x00000002, 0x00000001, 0x8042b088
IRQL_NOT_LESS_OR_EQUAL address 8042b088 base at 804200000 date stamp 41773335 - ntoskrnl.exe

the blue screen syas you have an ntoskernel issue. Some troubleshoot it by disconnecting / disabling as many devices as they can. It is not a specific error. Here a description :     http://kadaitcha.cx/stop_err.html


maybe these can help :

You can also try a repair install :

or try running sfc /scannow from the run box

Thanks to all.  This has been an incredible learning experience, particularly in the area learning what tools are available in win2k that I did not previously know about.  I believe my startup problem is corrected.  Using the win2k program; verifier, [which I did not previously know existed] I discovered that the driver causing my problems was winpoet, a program/driver required by verizon for DSL internet connection. When I connected the router to my computer, winpoet became redundant, and was causing my computer to randomly shut down and restart during startup.  I uninstalled winpoet, and everything seems to be working correctly.  Because the initial problem was random,. I will watch it for a couple of days, but at this point, I do not expect the issue to reoccur.  If within the next 48 hours the problem does not reoccur. I would like to split the 250 points.equally between mwnni and nobus; each of whom provided a considerable amount of information that ultimately led me to find a solution through following other links within the links they suggested.  A million thank yous for your assistance ~padre01 [Bob]

I gave half the points to nobus [125].  I would like to give the balance [125 points] to mwnnj but the point awarding box has disappeared.  Please tell me how I can allot mwnnj the points he deserves. ~padre01 [Bob]

Hi padre01,
thanks for your very feedback and i'm glad you've solved your problem ,not only you 've learned something new!
Don't worry about the points,cuz i 've received those,don't know what the mistake was,but actually i got the whole points you graded me!
Nice time !
