|Towers don't shut down monitors. Monitors either work or they don't. Maybe the graphics card is bad (if you have one)? Please explain the problem in more detail & tell us if you made any changes to the system that may have brought on the problem. Also, why do you feel changing the motherboard is going to fix it?|
I believe the correct model number for the "1920" is SR1920NX & for the "1720" it's SR1720NX.
The 1920 uses an A8N-LA board, aka Nagami2L-GL8 (GeForce 6150LE/nForce 430).
The 1720 uses an A8AE-LE board, aka AmberineM-GL6E (ATI RS482/SB400).
Notice they're based on different chipsets so if you were to swap the boards, Windows would most likely have to be reinstalled from scratch. And if you're running XP & have a SATA HDD, you'll have to know how to do the SATA installation. The HP disks or recovery partition probably won't work so you'll need a retail XP disk with the SATA drivers slipstreamed into it to be able to pull it off.
EDIT: the A8N-LA is the better board, the A64 is the better CPU. If you swap boards, make sure to use the A64 rather than the Sempron.
