My Canon C3100 boots and at the end of the boot display a blank screen. i need help

Does the machine initialise? You should be able to hear it??? If not then it could be the formatter board but if it does initialise then check the screen or the cable

u need to check power and then remove ram chip from mother board and clean the coper points with white pencil rubber. if not then u have to enter recovery disk if u created or boot with booteble disk and select f8 and select boot with last known good configuaration.

please see the flow chart and fix it. God bless you

The splash screen with the LG Flatron logo is the monitor's splash screen not the PCs.
The machine is NOT booting up the splash screen is the monitor coming on.
Remove the 1Gb stick an see if the machine performs normally.
If it does then power it off, remove the power cord and CAREFULLY reinstall the new stick.
If it fails to boot you may have a defective memory module.
If the machine fails to boot with the new stick removed make sure you have the original memory seated properly and all cables securely attached

1. check your video card it may not be seated in the pci slot provided on the mother board or it may have lost the driver set. This will require a re-install of the video card. If the video card is on the mother board this will require another video graphic card to be install via the pci slot or pci express graphics slot compatible with your PC.

In that case, looks like you have a faulty motherboard (video chip) chip-set. Remove motherboard from the casing and apply thermal paste. Also clean-up the whole board. I hope this will help you.

the prob. is boot ram

Did you clean the contact of the boot rom? Are you sure you have the right boot rom? Why did you replace the boot rom? Good Luck..

remove the battery and try to start the machine om AC power only

Have you tried pressing F8 on boot-up and log into safe mode under administrator, no password, and right click on any empty space on the desktop, left click on properties, left click on settings, select a lower resolution,( e.g. 1024X768 ) select apply, select ok, reboot, log in as normal
