Question about Acer Aspire M1201 Athlon X2 320 Gb PC Desktop

3 Answers

I just installed a new motherboard and graphics card. I had this done at a tech shop, so they should know what they're doing... Anyway, the card is a ATI Radeon HD4650 PCIE 1024MB GDDR2. It's installed in an Acer desktop... Acer Aspire am1201-b1603a with 3gb ddr2 memory, 320 gb sata hard drive, etcetera, etcetera. I earlier learned that the motherboard in this computer was fried, so I had a new one installed at a tech shop. After a few days of exceptional-quality graphics, I now have an issue where when i surf the internet, my computer freezes completely and no keyboard commands work. I end up shutting it down by means of holding the power button in, then restart it. This happens all-too-frequently. No idea what to do with this unbelieveably problematic desktop computer anymore. (My power supply is big enough to support the card, by the way).

    Windows was reinstalled and I recently updated the radeon video card driver.

  • dragon_obses Jul 27, 2009

    The drivers for the card are up to date. Windows was totally reinstalled.

  • dragon_obses Jul 27, 2009

    I will check the voltage on the wires you mentioned and get back to you. Sounds to me like a legitimate issue. Sounds like you know your stuff, too.

    I have a 500 watt supply, so it's got enough power. I also have a reliable anti-virus program installed, and have recently scanned my computer. The computer has no viruses.
    I also keep my running programs to a minimum, because I know that more programs running means more issues with this computer.
    Memory may be something to look in to. I'll have to check things out.
    Games aren't something that I constantly download off the internet. The only game that I have installed on my computer is World of Warcraft. I recently formatted the entire computer, and I make sure that I keep away from programs that I know I won't use, or that will clog my memory/resources.
    Oddly enough, when World of Warcraft is running in the background and I'm using the internet, the computer doesn't freeze. I have been using this as a solution.

Well that is a new one. I always thought that the hardware of the computer drew the power from the supply and for the hardware to run properly the drivers do that trick on request. But the power rating of the supply will accomodate the drive motors are the ones that use the most wattage. Less than 300 watt supplies are the ones that will show you a flip flop...
Well since you surf the NET the bidg spider web... and you may have an anti virus program I guess go to trendmicro and use housecall it is a free scan just takes time this site is safe.
It really sounds to me that you have alot of programs running in the background that is using up resources and if you are using explorer 8 *ate Yes it is a realestate hog it eat memory that is your resources CTRL-ALT-DEL task manager tap into performance tab PF usage should be lower than then 0.5 of your total memory 3/4 usage is a red area! This usage is a gauge for your resources.
You may have to increase your memory or reduse whart is running or sitting in standby...
The memory today is less expensive than in the early years.
I expect you have went hog wild trying new things on the net installing games and never uninstalling them and they may be sitting in standby mode in your memory which is eating your resources.
If you card ran good for a week and suddenly you are experiencing poor running performance and the images are great as they where after the video install. Yea they know what they are doing and you are just learning this! Otherwise you would of did your own work...

    You use a game program as a solution? Then the solution is the relation! I worked on computers since the late 88 and never had seen using a running game program to be the solution, I have no other way but to believe you, it was always the removal. Programs can occupy and run in the back ground undetected, the hackers ultimate goal, not saying that is the thing. Your game relies on connecting to the net? Well I question that game just by your descriptions.

    Reliable anti virus (name it) please, you did not check the memory usage in the task manager???? The effort is so small in comparing writing back saying you did not look... Seeing this will tell you, you are running at minimun, not assuming on the users part. Not a constant but you do download games ???

    One thing after you had reformated you HD, or whole machine that is, did you have a problem right after that? Did it run great until you installed something like the ( problem/solution)...

    Well it that game is the solution save face it might be the responsable item! I never heard of any over powered power supply giving a problem such as ... It was alway that when the load overwhelmed the power source a shutdown or a blackout happened.

    In the 20 years on repairs and I seem a mass of computer problems. After 8 years the problems were just repeated same ones over and over. Solutions become, yep, I seen that before type thing. One or two were new discoveries but in most part a 98% are in archive form! Now I do not know much of Vista it is new and might have a load of new items that are problems.

    the other has an extendes port 7 extra and they are all filled some used and some are standby.

    An internal CD player

    1 floppy drive

    350 Watt power supply runnning the whole computer

    I had to replace the supply once last year It finally broke down like a light bulb.

    Other than that the machine never had a related Power supply problem.

    Yea I had to reformat yea it did get slugish yea I found viruses yea I found programs running, yea I had memory leaks any certified programmer know what that is, I also discovered that the best is Trend Micro. Nortons and then non!

    Micro trend has a free housecall at their site FREE and they have to be reliable their future is Anti Virus no fly by nite organization.

    So what I am saying if this is academic and they are documenting this about the supply the problem is questionablly related I have an electronic's 2 year degree and 8 years in that feeled 20 years of computer experience and never was certified but when I hear real people that I have a face to face tell me that they brought their machines here and there and they were not satisfied..

    They ask what did I do different to fix it! I do not know because I have no idea what the other guy done...

    Also in IE 7 or higher

    go into tools

    internet options


    delete all

    delete add on files, check box checked

I understand that your power supply may be large enough, but there is a problem with it.

When you use any system, the base power supply is about 350 Watts. However, for every two drives you add to the system, add about 50 Watts. PCI cards about 20 Watts.

I suspect that if your system is freezing all of the time, check the voltages on the +12 V yellow, -12 V blue, and the red, and white wires.

When the voltage difference from positive and negative voltage exceed .4 watts difference, then the computer starts freezing. I've tested over 100 power supplies.

Any other questions, I am a certified A+, Network+, and Server+ technician. Studying for my Linux+ certification.

  • dbucyk Jul 27, 2009

    Did you have the power supply checked on all voltages? If the discrepancy is large enough between the positive and negative voltages, that would explain your problem.

    P.S.: Do you have the manual that came with your acer aspire am1201-b1603a? If you do, would you be willing to email me a copy of the manual?

Sounds like some kind of conflict. Make sure you have the latest video drivers for your OS. Was the os reinstalled after the new motherboard put in? This could cause problems if you actually managed to get windows running without reinstalling.

    Do you have any ATI software running controlling the card, if so try removing this so you are only using the driver. If still no joy restart in safe mode and see if the problem persists so we can rule out other problems.

I want to upgrade my graphics card, i currently have a Nvidia Geforce 7300 LE installed, which is 128 mb. Which new grapihic card can i install in my motherboard?

Hello here is the homepage for your mainboard:

Your mainboard is using the PCI-E 16 socket.

This is great because all new graphic card has this socket.

I would choose a AMD graphic card, 1 to 2 gb in the 6000 series.

Price is around 100 to 200 dollars.

But some of them will need external power from the power supply
as they need 100 to 200 watts, depending how much money you will spend.

You will maybe also need a new power supply for at least 500 watts.

A local computer dealer or online shop can sell you a great graphic card.

Please uninstall all old nvidia graphic software, before installing the new graphic software.

Good luck

Myn mother board is amd i will play games but some games would ask for graphic card but i hesitate to use it is there anyway to play games with out using graphic card

Some games will work fine with the on-board graphics card, but the newer and/or more powerful games require a more powerful graphics card. These will not run unless you install a good graphics card in your machine. Sorry.

In that way no need to change the BIOS settings, you can install a new graphics card directly. Once you are already installed the new graphics card you need to install also the driver so that it will work properly. Connect your monitor cord to the new installed graphics card. Now you can enjoy using your computer with the new installed graphics card.

I get no video and the monitor is good. Need to

IT doesnt matter. If the Video Card is built into the Motherboard and has failed; you can get NEW Card that can plug into an Expansion Port on *********** board

Make sure your motherboard is compatible with the NEW video card. For example, PCI Express video cards won't work with motherboards designed only for AGP or PCI video cards, and vice versa. has a good selection. Call their Customer Service Tech; they have great prices, sales and knowlegable Customre Service Tech to Check if it is the right Type of Card. Its probably PCI but check anyway.

Simply shut down unplug and open the computer side panel and go to the back of the Machine. If there is a separate Card (it will be obvious as it has a VGA port) Remove it and just install your new card in its place and plug in your Monitor to the new VGA port. If not then just POP OUT A FREE SLOT in the back of your Computer next to the Plug In Port so the VGA port that the monitor plugs into stick out the back and plug in your Monitor.

Close , plug in and INSTALL THE SOFTWARE THAT COMES WITH THE VIDEO CARD. Set all settings to DEFAULT or be creative :)

Cheers !

I can't install a GeForce 6200 graphics card

Also, if that card has dual outputs, such as 2 DVI connectors, try connecting your monitor to the other one.

HP motherboard dangling sounds when powered on

f you switched monitors already, your graphics card is probably the problem. I would suggest to temporarily switch this graphics card with another one. Maybe you can do that yousef, or know someone who can. Do nt try this without knowing what you're doing, it could damage your graphics card.
If you have done this, or are unable too, please post here what happened.

If the results you get with the other graphics card are:
1. You do get signal, but it is very low resolution. This is what is supposed to happen. It means you do get a good signal, the video drivers for that card just aren't installed yet. I'm afraid your graphics card is broken, and that you're going to need a new one.
2. You still don't get signal. This could be two things. Either your VGA cable is broken, or your motherboard is broken. I would suggest trying another ble. If that still doesn't work, you will have to purchase another motherboard.

I hope this helps,

I have a enbuild graphics card i cant play games . while installing it does not support.It shows error

Many of the onboard graphics solutions are not able to handle a majority of the popular games on the market today. Motherboard manufactures know this and so don't put too much thought into upgrading the onboard solutions, being that a great majority of avid gamers would by a graphics card anyway.

My first thought is to buy yourself a graphics card. You probably wont need anything overly special (although I am not sure of how much you may play games) but for decent beginner cards, they run you anywhere from $20-$80 these days. For a little more say ~$100, you can get yourself a decent card that can play most games on the market today. However, do take in mind what your motherboard can actually handle as far as slots go (PCI, AGP, PCI-E).

Monitor screen freeze with driver...

hi! you don't need to update the driver cause the problem is in your hardware. Graphic seems to be a bit grounded, try cleaning the contact pins of your AGP graphic card with eraser, clean it side by side and then put it back again to an AGP slot, then boot your CPU again. If it still the same, try it in another motherboard that support you graphic card just to be sure before we conclude that its the graphic card has the problem. Anyway if it still under warranty you can claim for a replacement to the store where you bought the graphic card.  Have a nice day!
