Could be a motherboard issues. That model is really not worth spending money on though. You can try to reset the BIOS on the system, unplug it from power and move the CMOS reset switch on the motherboard to the reset position for around 15 seconds. You'll probably have to reset the clock after that in the BIOS if it boots. You can't really "reset ram slots" unless you mean "RESEAT".
