My Pc Will turn on and USB ports work. fans ar spinning buy the monitor wont work (black Screen) and if i put my mice/mouse it work but my keyboard dont work even my usb to sd card reader wont work Here is a picture
did you always use your mainboard VGA? since it could need special CPU to work...
might mean you drain too much power from one of your USB devices...
yes and normaly it workeddid you always use your mainboard VGA? since it could need special CPU to work...
might mean you drain too much power from one of your USB devices...
What CPU do you have?
Do you have a graphics card?
Can the BIOS be accessed?
Have you tried running the monitor off of a different port (like HDMI if you have it)?
Have you tried a different keyboard?
Have you made sure none of the power connectors have gotten loose?
Highly unlikely, but if you have another PC with the same memory type, can you make sure your ram isn't faulty?
Have you tried removing the CMOS battery and putting it back in?
i tested it duhCan you please describe your diagnostic methods?
How do you know it works if you don't get a picture?
Are you perhaps connecting to the computer via network to check it is alive or something?
How do you know your mouse and keyboard are /(are not) working?
What did you actually test?i tested it duh
no i dont connected it via nw
i think his celeron processor might not support intergrated graphics... some mainboards of this era have the the problem the graphical output only works with intergrated graphics...It’s a Core 2 era system using integrated graphics that’s not displaying anything on screen when booting. That tells me power is ok but the graphics (or more) may be dead. Could be CPU or RAM, but impossible to tell from the information provided.
Beep codes would tell us exactly what is dead, if it has a speaker on the motherboard. However considering the age of the motherboard plus the fact that it’s a cheap-as-chips motherboard, I wouldn’t be surprised if it just died.
Something to ask would be when it stopped working, and what were you doing before it stopped working?
could be, just to not forget the option... could be since he also claims it starts when USB-keyboard isn't used that it drains a too muych from USB, or his main board needs a PS/2 keyboard to start (i had one that had this amazing bug before).But he said it used to work. That implies that the Celeron he has is one of the supported ones.
