Can i run new ati radeon 512mb video memory with 5.0 shader card on acer ACER AST690-U-P925A


1) How much Ram Memory do you have installed? If I have the spec's right, your motherboard's maximum amount of Ram Memory is 2GB.
(PC2-5300 would be best, but the amount is what matters, not the 'speed')

2) What is the Maximum Wattage for your Power Supply?
Takes power for each hardware component in the computer.
Motherboard, Processor, Ram Memory, Harddrive, Optical Drive/s, Graphics Card, etc.

When purchasing a graphics card, this is one of the minimum system requirements you need to know.

Spec's I looked up indicate a 300 Watt power supply.
This is the problem. That, and power supply's Acer uses are low quality.

If you had at least a 400 Watt power supply, you could use this,

Slap that game around, and make it bark.

You could also run this if you had the above Power Supply,

[Note*
No. It does not matter if you are using DDR2 Sdram ram memory, and the graphics card has GDDR5 graphics memory.
A graphics card runs independent of the system resources.

How to build a or assemble a computer and troubleshoot?


Building a computer will require: a motherboard, a processor, memory, a video card or motherboard with onboard video, a sound card or motherboard with onboard sound, at least one hard drive, a CD or DVD drive, a case for the computer components, a power supply, fans to cool the computer, an operating system, a monitor, speakers, keyboard, mouse, 2-3 hours to assemble the computer.
You must ensure that all of the components are compatible with one another. After receiving the parts, lay everything out on a large, clean surface. Make sure you are grounded by touching a metal surface; this will prevent the transfer of static electricity to your computer components.
Typically, the steps to install the components are as follows: 1. mount the power supply in the case, 2. mount the motherboard 3. lock the processor in the socket on the motherboard 4. insert the memory sticks into the slots on the motherboard 5. mount the processor fan on the processor 6. insert the video card into the applicable slot on the motherboard 7. insert the hard drive into a hard drive bay in the case, 8. insert the CD drive into a CD drive bay, 9. mount any fans you have to the fan cutouts on the case 10. connect all applicable data cables to the CD and hard drives 11. connect all applicable power cables to the motherboard, video card, processor, hard drive, CD drive, and any other components. 12. connect the front panel USB, power, lights, and reset connectors to the motherboard 13. close the case 14. connect the power, monitor, speakers, keyboard, and mouse to the computer
Because this process is rather involved, I recommend following a guide such as this one: http://www.maximumpc.com/article/how-tos/how-_build_silent_gaming_pc
It details the process, includes pictures, and even provides a list of compatible parts.

Acer veriton m460 won't turn on fan runs that's it


Power supply failure. Replace it. Get 50+ more watts than the original. Power supplies are inexpensive and can be replaced without affecting your operating system or programs.
BTW: Many "failed" power supplies still can deliver enough power to spin fans and turn on the lights.
I recommend: www.newegg.com

If this helps please vote for my solution.

What is my limit in video card choise 128bit? ddr3? what is my original power suply 300w 400w? kispis@live.com


The sony has 128 bits to display video graphics where the hiden programs least observed during a media show on the screen is powered by memory known as ddr3. A video program being observed only requires least memory. Every picture loaded starts a new video pixels. One program is incapable of distracting 128 bits of video. Motion picture flow faster least requiring so much video bits. Opening several programs on the desktop takes away from ddr3. A certain percentage of ddr3 is required to display a motion picture video. A slow down in videos on the screen is an indication to close any displaying programs on the desktop.

Hi, when i power on it shows in brown color, (blink in brown) nothing dispalys, i changed ps, memory, processor. but didn work out


The only thing that's left is your motherboard. The usual culprit in a black out mode is the power supply and the motherboard. Try using a certified good motherboard. Try also to check on the display card. Also, check for compatibility of the power supply, the motherboard, the processor, display card and the memory

Just brought new memory for my acer aspire sa90 desktop,now my computer doesn't seem to turn on


i assume computer was starting correctly before? this is older computer and it is using sdram memory, locket on them sometime do not clip in correctly.

1. switch off computer
2. remove power cord
3. remove side wall
4. remove sdram
5. check sdram orientation and type, if they correctly align with registering notches
6. release lockets to max, (outward from slot)
7. re-insert correctly oriented sdram till lockets close into sdram stick (you may give them bit "help" to close in position)
8. re-connect power
9. start computer

if copmuter start normally, that meant tha tyou fixed the problem, if not, switch computer off and remove power cable, check motherboard power cable insertion, and repower again.

if computer start, lose cable was the problem.

if computer still do not start, remove new memory and re-nstall old one, if computer start, new memory will be a culprit.

if computer no fan "jig" and no light blink, remove all power supply cables from motherboard and connect in it's place new power supply, to exclude power supply problem.

if computer start with new power supply, old power supply will be the problem,

if computer do not start, and no joy with checking, but fan is running, including on the processor, this will indicate either, motherboard or processor died... if that is the case further testing will be required to determine which is exact cause. as in home situation there are usually no motherboard testing equipment, you need to go to more difficult path of changing the processor, checking video and haveing second computer on which you can test all of that...

replacement board for that processor on ebay cost from about $0.99 plus postage. if you need any further advice, please re-post adn if i am on line today, i will provide you with further procedure how to test your video, motherboard and processor.

if you find my advice useful, please do not hesitate to leave your comment and vote 4 for me, thanx!

Open your computer casing where the motherboard lies in and then remove the memory card, your new video card and then reset the BIOS, refer to the motherboard manual on how to do it. After resetting, plug in the memory card and video card. Close the casing and connect all the wiring. Power up your computer.

No video on new Gigabyte GA-MA770-DS3 motherboard


There are a couple things that you need to look at. The first is your power supply. I've had computers seeming to run fine with no video. Turned out to be bad power supplies.
Does your video card require a power connection? Many high-end video cards need an external power connection. If the card has a power connection, use it.
Have you gone in and checked the cmos settings? What does it say (if anything) for the default video?
Now remove all connections to drives (hard drive and CD and try for video. Try it.
Next, if possible, swap out memory.
After you've tried everything (including maybe burning incense), time to try a new motherboard.

Hello,

I would suggest checking the motherboard for any burned or blackened spots on the motherboard or any add-on cards that may be present. You should be able to get something on the display as long as you have good power and a good video card. You still run the risk of having a bad hard drive or cd rom.

Hope this helps. Please make sure that you rate this information.

Thanks
