Here is the deal. The computer first started crashing randomly, ussually while playing games or videos or programs. Then it just quit working. It would power on and the fans would kick in and work but the screen would be blank. I thought it was the graphic card so we bought one. Nothing changed. Changed out hard drive and ram and still nothing. bought a new CPU and replaced the old one and BAM it was working again. Not thirty minutes later after installing a new OS and getting it running again it started crashing like before. I cant figure this one out... could it be the motherboard? The motherboard sometimes says its in safe mode and that I need to check if the CPU is overclocked but I havent touched any settings like that and neither has my friend and I cant find them in the settings. here is the MB model if this helps K8N Neo4-F . Thanks in advance for any help, I cant find anyone that knows what could be causing this.
