When i start my computer it doesn't boot and beeps continuously for 5 seconds and then beeping restarts. I have also removed my GPU but the problem is same. My mobo is G41MT-S2P and core 2 duo e8400 processor with 2x2gb ram. Please help.I could usb boot ubuntu by removing my hdd. However it worked only one time. Next time the problem came back even without hdd.
