Hi, I got very BIG trouble now.. When I finished install the mobo correctly when I power on the windows work perfectly. But, when I leave it for 4 hours, the VGA screen is going to blank. and when I restarting again the Screen never come out. Any solution? Is it my mobo already broke down/

good day!
did you give it 24hrs to finish a charge?
the PC has a charging chip inside.
new battery from whom>?
the line pack is not a charger its line power pack,
it converts 120vac (or 240 outside usa) to 19vdc.(Or your spec)
the 19vdc runs the PC perfectly with no battery installed DOES IT>
that is the first test. the power pack must be the the correct pack
for:
voltage
current (never lower spec)
and watts.
if not the correct power pack it will now work correctly
the watts can be higher no problem,

if it runs ok on line power no battery
then we try the battery. (give it 24hrs for stubborn old batteries)
if the power pack is ok, it will charge, (spec pack as HP tells you)
if the battery is bad it will not.
if the charger chip in the PC is bad (MOBO BAD) then it will not

testing takes, skills and tools, one tool is a voltmeter
lacking that tool, one can only guess.
what not get your PC repaired by a TECH.???????

here is your HP page, its non trivial, no>?
see that they have 5 power packs used
that is BECAUSE they HAVE many power levels of CPU/GPU
faster rated CPU'GPU need more power.

you never once said
it runs perfectly on AC power only
not once
nor it does not overheat. nor if the fan works and vents all are free of lent.

FIRST, if this code comes back. Have a technician look at it DO NOT CONTINUE TO RESET the code!!!! AS this is for the Hot Part called the FUSER. It can catch on fire! And that will ruin a perfectly good day!!!!
1. Turn OFF the main power switch. (inside the machine leave the the power on switch on on the control panel)
2. Turn main power switch ON while pressing the Utility/Counter key.
3. Touch [Trouble Reset].
4. Check to make sure that [OK] is displayed and the it has been reset.
5. After turning off the main power switch, turn it on again more than 10 seconds after and check if the machine starts correctly.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/normanj_7893313f0751935f

That insulation is a very sticky mess. The hole size that you want to drill is not going to be big enough. You are going to have to get creative with trim and you should use a dry blow in insulation. The R value of the expansion foam is not as high as a blown in substance. Also using the expansion foam will leave gaps in the open space.

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up a computer hard drive

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your ((motherboard to your hard drive)) make sure they have a secure connection and are not faulty or just replace them there probably old and faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they are probably old and faulty a computer needs its connections to continue its cycle and have an end so any faulty leads will end up with a computer error

hope this helps

did you connect the power to the geforce card? it needs own power plugin.

Hi gordonal123, installing drivers through safe mode is not recommended. If you want windows to function correctly than do a fresh install of windows. Over writing the Gateway hdd will cause you more grief. Windows registry will go nuts.
Link to download the Asus K8V drivers.
http://support.asus.com/download/download.aspx?SLanguage=en-us
Here is what you need to do. Boot to your windows CD while using the Gateway system & hdd. Create a new partition within the free space of the Gateway hdd. (Follow windows onscreen instructions to create a new partition within the free space of hdd). (This will maintain the current windows function).
Restart windows when finished. Windows will create a second partition on the Gateway drive. Go to the Asus link above & download all the drivers for the K8V MB, onto the second partition of the Gateway hdd. Once downloaded & uncompressed into their own folders you can than boot to the windows CD & format the primary partition & install windows fresh onto the formatted partition. When finished you can install the K8V driver still located on the secondary partition. Copy & past these driver folders to your primary partition. Than use windows disk management software to erase / delete the secondary partition. (diskmgmt.msc).
When finished you'll have all the drivers for the K8V MB, no need to buy a PCI LAN card & more importantly a fully functioning windows with-out issues.

Good luck gordonal123!
Take your time.

You will be fine with nVidia 9800 ! thats perfect for your mobo.
Youst make sure you have enough of memory to, those games you talking about needs a lot of memory to work perfect.
I suggest you install at least 3GB memo, or even better 4GB. Thats the maximum of memory you can have on that mobo.

Here is the spec of your mobo

Good luck to you

Hi tmomonet, did you install you're PCI-E video card in the correct slot? Open you're manual to page 2-18. Once you have gone over that part of you're manual you will need to enter the bios to check some settings so you're video card boots with the system. (Please make sure you're PCI-E video card is installed fully into the PCI-E blue slot). (Some PCI-E cards also need extra power, if youre's does it will have a power connector on the rear of the card).
Once into the bios, open you're manual to page 4-20. Open PCIPnP. Than go to page 4-26. At the bottom of the page you will see, Primary Display Adapter. Change to PCI-E & not to PCI.
Save & exit the bios. You should gain video display. Once windows finishes loading, install your video card software.

Good Luck!
Mike

If your MoBo supports 4 Gigs, Vista 32 bit will only utilize approximately 3.48GB, and XP 32 bit will only use 2GB, so unless you are running Vista 64 bit (which will use up to 8GB, if your MoBo will?), the OS isn't going to see but 2 to 3+ depending on which version of windows you're running,

As for the slots being too big, you are probably attempting to install the wrong RAM for your MoBo. Compare the RAM in question with what the MoBo manufacturer says is compatible.

Good luck, and I hope I helped you.

1. Remove network card and see if restarts go away.
2. Remove all but one RAM stick and try it, swap that ram with one of the others and try again.
3. Try another power supply.

4. If windows was installed previously with old mobo, you may need to do a repair install of windows or wipe it and start over.
