Blank Computer screen after reboot

By cwl8621 ·
I have a K9N Neo nvida nforce 550 MOBO with a AMD 5200+ dual core and a x1950 pro ati graphics card. I got everything running but at first i got the error unknown processor revision. I fixed this with a forced Bios flash. No i can access my bios and when i start the computer it tells me to hit F1 for setup or F2 to use default settings. If i use default settings it goes to windows and starts up fine. If i go to setup and just his f10 to save and exit the monitor goes blank and nothing happens. The computer is running but the monitor is in standby. If i use the default settings without going into bios the computer works fine as i said, but after i restart the computer i get the same problem and have to reset my cmos everytime i want to get on.

JBat1 should have pins 1 & 2 jumpered. Verify this is in the correct position. Should be around page 2-18 of your manual.

Also are you saving the Changes when you Exit BIOS? If not this is the problem as you are not allowing the BIOS to run on it's Default Settings.

All that should be required here is to enter the correct Time & Date set to the Defaults and check that the CPU & RAM are correctly identified and then save the changes as you exit the BIOS Setup and let her go.

If this isn't working perhaps you have a faulty M'Board or it may have something to do with the NVidia Chip Set M'Board an the ATI Video Card conflicting. Did you ask anyone if there where known problems between the M'Board and Video Card?
