Question about Compaq Presario Notebook
It just keeps rebooting with no screen at all even with an external screen - nothing. I've replaced the ram with one i have tested on another pc that works.I've removed the battery ,reset the bios (removal of cmos battery) ran the system with and without the battery (direct power) all to no avail.I've even removed the hdd to see if that will show a screen to show problems anyway i don't know whats wrong any ideas please? thanks in advance
"it just keeps rebooting with no screen at all even with an external screen"
I take it you mean that everytime you reboot you see nothing.....not that when you switch it on the computer reboots?
If it is that it just reboots all the time, it may be that the screen is not getting enough time to show anything. However, there are some viruses that stop the screen from showing too...so to check that put the hard drive in to another machine and run a full virus checker on it.
However, IF it is that the machine does not have a virus, and/or that the machine IS getting enough time to show a screen, then I am afraid it is either that the video cable is not working (the cable that connects the screen to the computer) or that the graphic card (or mother board if you dont have a separate graphic card) is at fault.
