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 will keep rebooting about every 30 seconds by itself with no screen. Even if i use esc ,del, f10 keys ect makes no difference. The hdd seems to be ok (tested in different pc) It dos'nt seem to getting either to the post or skipping it then rebooting
I think some of the programming necessary for booting your computer was on the other ram you removed. I noticed the same problem when I added memory to my lap top. If I switched the original ram to the second slot from the one which it was in, the laptop does not start. It gives the same problem with the new ram in the old slot. I guess you could call it one and two since #1 is below the #2 slot in my laptop. Why dont you try putting the old ram in the slot it was in and add the new ram in a new slot? hope this helps

It's possible the power cord is defective only giving enough power for a partial boot. I would try another power cord.
If it's not the powercord then it would definitely be the motherboard not taking the power and distributing it correctly and you would have to replace it.
