Having problems with your HP Compaq Presario SR1420nx (SR1420NXPS69AA) PC Desktop ?

ASAP! Power Problems. Please Help!

\015 Recently my computer went through a power failure,surge. It turns on just fine but the monitor connection aint working. I know it's not the computer but its the connection between the computer input. My monitor understands the connection is there but it says no input detected. I resorted to calling a local computer guy and he says its the graphic card. I have another computer thats xp with a graphics card but I dont know how to replace it... or where it is or what it looks like for this make. Please help!\015

Answers :

There could be several things causing this issue. The power surge could have damaged the main board, power supply, graphics card or on board graphics, cd-rom drive ect. The problem is that one of these things could be bad and you need to figure out what it is. The first thing I would do is disconnect on component at a time and then re-boot the computer and see if you get a picture. Pull the cd-rom drive,then the floppy drive,then any modems. If you still get nothing then try the hard drive. If you disconnect the hard drive your operating system won't start but at least you should see the BIOS star screen come up. If that does not work then try taking the power supply from the working computer and install it in that one if the plugs are the same. You could try using the graphics card from the other computer but it may not be compatible. There are PCI,AGP, and PCI-Express cards. Make sure the graphics card slot on the broken computer is the same as the one on the working one. Also remember to ground yourself to the metal case of the computer before touching any components or static discharge could damage that part you touch. If you try all these things and it still does not work than it is probably a bad mainboard. In my experience when a processor goes out the computer will do nothing...no boot up and no lights.
\015\012quite straight forward and simple Fix.
\015\012it,s the card that the Monitors plugged Into.
\015\012there are different Types. Pci-Agp-Pci-express.
\015\012Assuming that your cards are identical, as mentioned above.
\015\012remove The power Cable from the Computer. take off the left hand side panel, usually 2 screws at the back of the case. Locate the graphics card. these are mostly secured by 1 screw to the back panel ( internally ) there is a release catch on the motherboard, gently pull tab downwards, to allow the card to be removed. replace in reverse order. plugging in the power cable finally. connect the monitor, and startup the computer.
