[SOLVED] internet connection causes crash

I'm a rookie with computers and I don't know where to start with this. I have an older Dell latitude and whenever I am connected to the internet, different applications stop responding until eventually windows explorer stops responding and I have to reboot. the strange thing is that the computer runs fine when it is not connected to the LAN. I can normally surf for a few minutes and then things start crashing. any suggestions?

 

My advice is go to housecalls & run the free online virus scanner.
Click here to do so!

for a free virus scanner you can add to your system... go get AVG. Click here to download AVG

and to protect yourself from hackers etc... Get Zone Alarm
Click here the free version is fine


then there is spyware ... go get Ad-Aware
Click here to download it


this should keep you in pretty good shape

scan & defrag

 

Since you say everything works fine unless you are connected to the LAN, I'm thinking there may be a conflict with the LAN card and another device.

Would you post your IRQ listing?

Start button, run, then type msinfo32 and hit ok...go to hardware, IRQs, edit, select all, edit, copy, and come back and paste.

 

IRQ 0 System timer OK
IRQ 1 Standard 101/102-Key or Microsoft Natural Keyboard OK
IRQ 2 System board extension for ACPI BIOS OK
IRQ 3 Psion Dacom Gold Card Global 56K+Fax (V.90) OK
IRQ 4 Communications Port (COM1) OK
IRQ 5 NeoMagic MagicMedia 256AV Audio Driver (WDM) OK
IRQ 5 ACPI IRQ Holder for PCI IRQ Steering OK
IRQ 6 Standard Floppy Disk Controller OK
IRQ 7 ECP Printer Port (LPT1) OK
IRQ 8 System CMOS/real time clock OK
IRQ 9 SCI IRQ used by ACPI bus OK
IRQ 10 3Com 3C920 Integrated Fast Ethernet Controller (3C905C-TX Compatible) OK
IRQ 10 ACPI IRQ Holder for PCI IRQ Steering OK
IRQ 11 NeoMagic MagicMedia256AV OK
IRQ 11 Texas Instruments PCI-1225 CardBus Controller OK
IRQ 11 Texas Instruments PCI-1225 CardBus Controller OK
IRQ 11 Intel 82371AB/EB PCI to USB Universal Host Controller OK
IRQ 11 ACPI IRQ Holder for PCI IRQ Steering OK
IRQ 11 ACPI IRQ Holder for PCI IRQ Steering OK
IRQ 12 PS/2 Compatible Mouse Port OK
IRQ 13 Numeric data processor OK

IRQ 14 Primary IDE controller (dual fifo) OK
IRQ 15 Intel 82371AB/EB PCI Bus Master IDE Controller OK
IRQ 15 Secondary IDE controller (dual fifo) OK

also worthy of note: I had normal internet access w/ no problems for about two months, then this last month or so I've been having the problems

 

Hi trabi11,might also help to list your startup programs.Go to Start>Run>type in msinfo32>click ok>click on the + sign next to software environment>click startup programs>click edit>select all>click edit,copy and paste the page back here.

 

Hmmm, I think the problem is here with your video card and the PCMCIA card on the same IRQ.....I'm doing some research right now.....

Are you using the com port on IRQ 4 for anything?

I don't know exactly how to find out if i'm using irq 4 for anything; how do I find that out?

 

Hi,

Allow me to advise you on these startup programs. You've got a couple of things running that are better disabled:

Go to Start/Run, and type Msconfig.
Go to the startup tab, and uncheck EVERYTHING, except the following items:

StateMgr
ICSMGR
LoadPowerProfile (2x)
on\RunServices
Norton Auto-Protect
Norton eMail Protect
PCHealth
ScanRegistry
SchedulingAgent
SymTray -
SystemTray


Click OK, close Msconfig, and reboot.

Good luck,

 

I believe the problem is fixed, thank you so much for your help everyone.

 

Did disabling your startup items appear to solve the problem?

 

I believe so. I have another quick question though, I just tried to change my background to a wallpaper that requires my "active desktop" to be enabled and the recovery warning screen came up right away and the window stopped responding. what would have caused that because that was actually my initial problem two months ago.

 

Did you enable active desktop?

 

yes

 

I don't think that would have anything to do with your internet connection, but if you continue to have problems with the wallpaper, open a new thread under windows.......you'll get better assistance as I don't believe that would be a hardware issue or if it ends up being hardware related, more than likely it'll be video/display adapter related........have a great day!
