I have a Hewlett Packard M8300F and it first started having weird problems with the harddrive running really slow. Then the whole PC died. Now when I try to start it first of all when you plug it in it starts up without pressing the power button.. and there is no image displayed on the monitor. It also sounds like the fan on the power supply is running higher than normal. I tried resetting the bios.. I tried moving the jumper to reset the bios password. both had no effect. I am going to be building a new PC soon and will try to order a new bios battery and I will try the new power supply for the new PC in there as well. Does anyone have any ideas what I might want to try? Also.. this PC doesn't have a dedicated graphics card but it does have a tvtuner card.
