Took it to the computer shop and they said it was overheating, so they put in new fans, which it was. The computer guy said that it's not a hardware problem. If it was then it wouldn't restart after rebooting.
There are no other problems with it. Everything works fine except internet. I have updated all the drivers.
The computer shop guy said write down the XP number on the case and reformat the hard drive, if nothing else worked, so I did and it still will not stay on line. I did however had it on line long enough to update windows and the drivers.
Tried TCP optizmer, regcleaner, disk clean up, defrag, new NIC cards, updated those drivers, new modem and called compaq and microsoft. Cleaned out the device manager and checked on what was installed and enabled. No one seems to know what is causing it.
Ran adaware, spybot and panda on line scan...nothing found.
Any help is welcomed.....running out of things to try.
