I have Windows XP on a desktop and sometimes when using the internet, it drops out. I can't repair. Only a reboot or shut down works. I run Linux Ubuntu as a dual install and have no problems, so I don't think it's a hardware issue in that respect. I also have XP on an old laptop (IBM 833Mhz - yes, old!) and have no issues. Sometimes, I have to use the desktop to work, copy files to the laptop, to e-mail!! Silly, isn't it!
Main desktop specs:
MSI motherboard PM8M-V Socket 478
Prescott 3.2GB CPU (dual)
ADSL Router D-Link DSL-502T
All hardware drivers have latest firmware upgrades. All leads are fine as they work with both Ubuntu and laptop. I re-installed Windows but am having the same issue (and yes, I had to re-install Linux, too!) It just 'happened' one day. I can't define what it was. Even a re-install of Windows a month or so ago gives me the same problem, and yes, I had to reinstall Linux as well.
I've trawled around like a lost dog for a long time thinking that perhaps it could be a Windows update that I selected on my desktop but not my laptop. It's a weird problem.
Sometimes it will connect, but will drop out between 5 minutes - 24 hours. Other times it refuses to connect for hours. I've tried the obvious stuff like virus scans, spywares, greywares etc, put my firewall (Comodo Pro) to the test, even tried other firewalls (Outpost, Zonealarm, CA Internet Suite) and other configs, keep alive connections, hardware diagnostics, power management, etc. All have no issues. There's no device conflicts in the device manager.
I would honestly appreciate any ideas people may have. I don't know how much information I should put here. I have pages of things I've tried and perhaps it's best to start back at the beginning.
Any help will be appreciated. I spent hundreds of dollars on Windows softwares and can't even connect to the internet at times. The problem's been going on for around 6 months and I'm out of things to try.
Many thanks in advance.
