Hello all and many thanks in advance. OS is WinXP and system is an Abit Is7 with a 2.6GHz P4 CPU. 4 512MB sticks of Corsair Value are using up the RAM slots and timings are 2.5 3-3-3. It only has 1 HDD (a WD 120GB SATA) and a Radeon 9600SE AGP card. I get reboots mainly during heavy Photoshop and Adobe Bridge usage. I have looked over the BIOS to make sure everything is good there. Thanks again.
