Question about HP Compaq Presario SR1300NX (PP195AA) PC Desktop
I ADDED MEMORY CHIPS TO IT. NOW MY MONITOR WILL NOT COME ON
Doesn't turn on (power), or will not display anything?
Bad memory chips will cause the display to be inoperable.
I once put PC-2700 chips in a laptop that would only take PC-2100. The chips I received were wrong, but I didn't check before installng them. Anyway, it worked like a champ for about 5 mo. Then the display went out. I could tell that the computer was still operating, so I sent it back for warranty repair. Of course, the chips were aftermarket, so it wasn't covered under warranty, but that was the problem.

Shine a flashlight on the dark screen to see if you barely
see the icons on the desktop. If so, then the LCD Inverter is bad.
Plug in an external monitor and see if the display shows up on it. It can be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If so that proves your video card is ok. The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.
If you see no icons by shinning a flash light and the external monitor works, then your screen is bad. If you see no icons by shinning the flash light and nothing shows on the external monitor, then most likely your video card is bad.
If you don't think the system booted all the way then try the steps below.
Beep tones and blinking lights tells the technicians what is going on with the laptop and why it is not booting. Most times it's a motherboard issue when you hear beeps or blinking lights continuous. Most times the problem is with the memory or Video Card. Count the Blinking Lights or Beeps and take note of their pattern (1 Long or 1 Long followed by 2 Short).
Maybe your memory is bad or the memory slot is bad.
Remove the Power Cord, Open the Case and remove one of the memory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x on it with an ink pen. If it fails to boot then move the chip to the next memory slot and try rebooting. If it fails take the chip out and set it aside, then put the other chip in and try booting it in both slots. If it boots, just to verify that the chip set aside is bad, mark an x on it and put it into the open memory chip slot and try booting.
