Hp pavillion vista won't shut down


I think your at the point to do a Full System Recovery. Do you have a Factory Recovery Partition? You didn't supply the Model of HP or the OS you are using?

Installedmemory now pavillion ze4610 just beeps and shuts down.


Make sure your battery is removed, unplug, reseat memory mods, make sure they are inserted fully. I assumed the 512MB are used? New? There is no reason , that I can come up with, they should not work? I have upgraded many memory mods without incident.

My hp pavillion computer shuts down same time nearly every day.


This is probably due to having a scheduled task that shuts down your computer. Check your scheduled tasks, and delete the restart entry.

I want to upgrade video card for my pc(HP Pavillion a1120n) i wanted to know what kind of video card is compitible with my pc. please help thanks. ;)


From what I gather, your computer has a PCIe v1.0 slot for a video card upgrade and comes with intel on-board video. So you will need a PCIe 2.0 video card (v1.0 are no longer available and 2.0 are backwards compatible)

I assume, like most PC's, yours has a 350-450 Watt Power Supply. Check your power supply to be sure, you just can't put any video card, you are limited to the available power from the power supply. If you want a top of the line video card for gaming you will need a more powerful power supply. If all you need is better performance and better video quality (DVI/HDMI) then any sub $100 dollars card will do.

I cannot emphasize enough, check your power supply wattage capacity and the watts required by the new card before buying.

Also, do you have additional power connection from the power supply for the new card? most cards, not all, require a 6-pin PCIe power connector.

For the average user I recommend:

My hp dv 8000 Pavillion laptop will turn on and then it immediatly shuts down after 5 seconds or so


Power drain would be a better solution in this case. 1.first shut down the comp 2.unplug the charger 3. remove the battery and after press and hold the power button for 60 seconds without any charger and the battery.After the 60 seconds replug the battery and the charger and turn the computer .
and if this doesn't help
then try to take out the ram or memory chip from the computer and place it back.

You are confusing Hibernation, where the RAM is written to the HDD and power is turned off without unloading the OS, with Screen saver (control panel - display).
