Are you still using sp2?
tell us more about what your setup comprises eg hardware and software.
First thing though make sure you have latest bios version and motherboard drivers and that all your hardware is functioning OK - look in device manager - also in "system's information particularly in "problem devices"
In your bios make sure your settings are set to "setup defaults" and that any onboard devices such as modem or graphic are turned off if they are not in use (particularly those items you have an extern card eg graphics).
After uninstalling SP2, my computer reboots 4-5 times each time I have to restart it. I had many conflicts between SP2 and my ISP, Adelphia cable, took my computer back to the builder and he reformatted. Everything seems to go ok except this rebooting. I have a fear that one day, it will just keep doing this and not run. Seems to load part of the bios each time it reboots and finally gets it loaded after all these tries. I'd appreciate any suggestions you might have. Thanks!
