I've been getting frequent crashes recently. The computer seems to work fine for long periods of time, but will then blue screen and restart over and over. Eventually I'll get back into windows and get a dialog stating that the system has recovered from a serious error. A webpage pops up and tells me to test my RAM, system board, CPU and PSU. I've tested my ram with no problems, my question is...How does one test their CPU or system board? I'm using an A8N sli-delux with an AMD64 3400+.
