Re: ASRock K7VT6, Athlon 2600+ I left my system running the other day and came back a few hours later to find it had not hibernated but the screen was blank, the fans were running and the power & HD lights were lit. I hit the reset button and nothing happened. I turned off the power supply. Now when I try to power up I only get running fans, and the front led's (power& HD) stay lit. I am down to the point now where I have 'bench tested" the unit with only the MOBO, CPU (with heat sink and fan), 1 stick of memory and the speaker connected. If I short the power switch the fan starts running, the CPU gets warm but no beeps, nothing. I think I am down to either a bad MOBO, CPU or BIOS. How do I check this further. Below are some of the things I have tried: 1. Went thru a multimeter check list, PSU is OK. All voltages on ATX connector OK. All ATX ground circuits on MB OK. 2. Removed all components and connectors from MB & reinstalled 3. Cleared CMOS by jumper, and also tried to clear by removing the battery. 4. I have tried a spare, known good, PSU. 5. I have tried both sticks of memory alone in slot 1.
