Question about HP Compaq Presario SR1720NX (EL435AA) PC Desktop

2 Answers

Compaq desktop - problem started with blurry monitor, then after a reboot I get nothing on the screen. Plugged monitor into different PC and it displays fine. Appears as though system doesn't post - no beeps, no bios startup...nothing. Processor cooling fan runs at high speed constantly. Pulled RAM and started up - still nothing on screen. Replaced motherboard - same issue still exists. Any ideas?

The only thing left that i can think of is your power supply not giving enough power for the system. Try to unplug all unused drives ( keep the c drive for start up ) remove any sound cards or network cards and then reboot. If it boots up then you definitely need a ps.

My e machine desktop logs into my windows then when its load my stuff it goes on a blurry screen.But here is the tricky part when i rebooted my computer its fine for a day until the next day then it does...


Sounds like a video card, cable problem, or monitor issue. I would first start with trying to replace the video cable from the desktop to the monitor. If the issue persists try connectiong the desktop to another monitor, or TV if you have a newer tv. (most tv's now how a VGA or DVI input on them) If that does not resolve the issue it would most likely be the video card. you can pick these up for pretty cheap. they are really easy to install.

Black Screen Compaq Presario


Do you see the BIOS splash screen or anything?
Try booting into safe mode by pressing F* as soon as you power on the computer. If the monitor works, then it is a bad driver. Roll back to a previous restore point, boot to last known good coonfiguration. Last Known good configuration is available from the same as the safe mode screen.

If this is helpful, please comment and rate. Have any other questions, please let me know.

My compaq sr181nx diplay monitor is now blurry


This could be a faulty monitor. Trying plugging in a different monitor to the computer.. If you continue to have the same problem with the second monitor, then it is your video card or on board video that is going out. If the video is fine after you tried the second monitor, then you need to get a different monitor for your system.

Try to connect tv as a monitor


Does the desktop have an S-video output on its video card? If it does, you only have to get either an S-video cable and hook it up from the computer to the TV, or get an S-video cable plus an S-Video to composite adapter, and hook it up.

For the video card to output to S-Video, you may need to fiddle with something in the control panels, or unplug the regular monitor and reboot (at least on my NVidia 5600 cards, this forces the card into using the S-Video output).

Personally I think you will be very disappointed. Using normal computer applications while using your TV as a monitor will be basically impossible; the text will be too small and blurry. Web browsing on picture-and-headline type pages will be OK, but everything else? Instant headache. Most applications that are designed to be accessed via a TV screen instead of a TV monitor have huge font sizes and lots of contrast (cf. the TiVo's interface, for example); they're designed much differently than desktop apps. You may want to look into screen-magnification apps to make it easier on your eyes.

regards,

hope

Compaq presario sr1115cl wont power up


Remove the power supply after everything is unplugged and take it to your nearest electronics store. They should have a tester there. This is probably the problem.
