recently i've been getting warnings about a low cmos battery, and checksum errors. i go into the BIOS and set it up as per my req's, since it loses all the settings upon powering down, and all is ok until i cold boot, where as this happens again. if i just reboot from the start menu, it reboots ok. this mobo is only 6 weeks old, it's an ECS K7S5A Pro with an AMIBIOS. i've also noticed that my hdd activity light sometimes stays on constantly, so i'm assuming the hdd is spinning more than seems necessary. is it possibly more than a low cmos battery? maybe a faulty mobo?

hard drives spin at a constant rate.regardless how much work they do. the light indicates how much the hard drive is being acessed. try a new battery any ways it could have been faulty. sat to long on the shelf. worst case senario is some thing shorting on the mobo. you will know if new battery dies at same rate as the last one. now you can do online scan for trjins and viruses. free trojin scan http://www.trojanscan.com/trojanscan/scanner.htm panda scan http://www.pandasoftware.es/activescan/ housecall http://housecall.trendmicro.com/housecall/start_corp.asp d/l mcafee,s stinger http://vil.nai.com/vil/stinger/ you may allso want to d/l fprot for dos its free and you can check bios-cmos for virus.
