I have a Hp Pavillion Slimline s7520n. My monitor display was dancing all over the place so I ran a dedicated line solely for the PC. Now during the start up the PC freezes and stops comminication with the monitor. I get the "no signal" display and everything stops? Help, please.

    What I meant by a dedicated line was that I have a single line running from my electric panel to my PC - absolutely nothiung else is on this electric line and the grounding on my house has been checked.

    It had been suggested by numerous people that my monitor display was jumoing around because of electrical interference...obvioulsly that theory has now been disproven.

    When I turn on the PC now...i get nothing but a blank screen.

    My total lack of knowledge is telling my that my viseo card and/or motherboard is dying a slow death.

    i will start fresh with the PC tonight. Assuming I might be able to get to safe mode what do I do from there? Thanks

  • shavawn Sep 11, 2009

    I started fresh...

    The PC booted up and asked me if I wanted to start normally or in safe mode. I was able to scroll up to safe mode and hit return. The screen blinked and went back to the same screen and asked the same question. But this time i was unable to scroll to tell it i wanted to start in safe mode.

    The 30 second clocked ticked down and it started to load windows. After a few seconds the monitor said no signal and shut itself off. The PC appears to be on but it is not thinking or making any sounds - except for the light on the front of it i woudl think it was off/dead?

I'm somewhat confused over the dedicated line....If this is a monitor issue re: display jumping all over, I'm surious what you mean about a "dedicated Line". There should be either a VGA or a DVI cable connecting the Tower to the monitor. What I would like you to do is set the computer back to the default setup it was intended to have a reboot the computer into safe mode. Reboot and when the HP splash screen appears, tap the F8 key until you see the multiboot menu appear. choose "Safe Mode with Networking" If the computer boots up and the image is stable, it is not a hardware problem, you most likely have a "driver" problem and those can be upgraded by visiting HP support / drivers. Place the model number of your computer in the search box, click on the appropriate operating system and you will be given a menu of the appropriate drivers for your system. Download or Run the newest graphics driver they offer. Reboot when installed. When you install the graphics driver, remember that it may take a couple if minutes for the driver to start installing....just give it time. Good luck, ParrotHead PC Repair

    Try to get to Safe mode and we'll take this in baby steps..Lets just hope you have a bad driver.

    Getting to safe mode will tell me that the problem is not hardware related. You can then go online to the HP Support Driver page and download all new drivers for the video card. I can give you a walk through for that IF the computer boots.

    Well, since I don't have my hands on it, I would venture to say that you have a hardware issue. Not sure if it is the hard drive or the motherboard. If you start the computer try to get to the BIOS page, and go through the different pafes there. You access the BIOS by tapping either F2 or Esc during the splash screen. More than likely it is F2. It will say entering setup. If you can get into the bios and change settings....then I would lean toward a hard drive issue or a PSU issue (Power Supply Unit). Power supplies have been known to wreak havok with computer systems when they go offline. I hope this at least gives you a direction to point at if you take it to a shop. You can always just try to purchase a PSU for that computer, most retailers carry them for under 50 bucks and they install with 4 screws in most cases. The hard drive is just as easy and just as inexpensive depending on what size you get. I wish you good luck in your quest. ParrotHead PC Repair

Change HP Pavilion Slimline s7520n Video Card?

The on-board RadeonXpress 200M graphics is a dog. It offloads a lot of work to your cpu, and shares system memory which ties up the bus and detracts from the memory available to the OS.

The s7520 suffers from thermal problems due to it's size and poor ventilation. It also has a very limted power supply. Therefore, your choices are also limited. If you could score Radeon X600 or X1300 with 128MB for cheap somewhere it would be a worthwhile upgrade. It does need to be PCI (not PCI-E) and half-height (low profile).
