Hello,
Click here to download the latest version of software for your audio driver for Compaq presario C770US.
Please let me know if you have any further questions or concerns.
Thanks.
Unplug all the Cables from Compaq Presario 5103 CL and leave the Keyboard, mouse and monitor cable pluged in.
Now make sure the power cable of the monitor should be pluged in and the power cable of the tower should be pluged in.
Now to check if the montor is fine just unplug the video cable only which will show no input signal on the screen. If it shows this signal the monitor is fine. Plug back in the video cable.
If the monitor is going to sleep mode it might be possible that the old computer ( Compaq Presario 5103 CL ) is in stand by mode. hit any key on the keyboard and it should come back .
If it is not in the stand by mode then do one thing. Check the same monitor with the new computer. If it is working. Perfect ..!
Do one thing now ..!
Unplug all the cables from your old system and then press the power button for 30 sec and let it go. Now plug the keyboard, mouse and the monitor try again.
If it works Perfect. If not ..!
Then you need to open the tower and check on the processor FAN is it running..? If its not running you will not get the display as the fan is responsible for the display on the screen. Otherwise...!
Check the Tower possibly the Tower is not getting the power.
go to control panel -device manager and see if you have all the latest drivers downloaded and if u dont then i would try and update them. if that doesnt work search up the specific driver u need online and download and install it.
