Not built in, you would have to buy a seperate wireless card and install it. USB ones however are very simple to install and only cost about $30-$40.

No, a stick of RAM only needs 10 watts at most. Something is wrong with the new memory:either it's too big or it's the wrong model.

Hi Keith... here is all I could find on this machine, I assume this is how yours is set up. Component details are almost impossible to get on E-machine units, they just do not provide them.
  • Processor Intel Celeron D 356 / 3.33 GHz
  • Memory 512.0 MB / 2.0 GB (max)
  • Hard Drive 120.0 GB - 7200.0 rpm
  • Operating System Microsoft Windows Vista
First, you want to check to see if your proc even can be changed; many of E-machine procs are permanently attached to the motherboard and cannot be removed; this is the cheapest way to manufacture a computer, and E-machines is bottom of the line quality computer (no insult intended, just fact). Since I don't know what CPU socket the T3604 has I can't tell you if the Intel CPU would fit it. Next, I don't know what the Northbridge is running at; if it is less than 1066 there will be a bottleneck and there is no significant gain. At this point, I suggest that you not spend a lot of money on this, better to save and build your own computer. If you are a hardcore gamer looking for high framerates you really don't want this machine. Better to load in more RAM if you have no other options. Here is something I ran across:

If I had the above details I could give you an answer.

www.dynamite.com might still sell what you want :> Just kiddding!
Try a complete wiping of the hard-drive unless you are doing an upgrade, you will lose all data on the drive. If that doesn't work, you might not be running enough ram memory for 7 to run cleanly on you machiine, go ahead and upgrade.
Hope this helps!

I found the micro switch power button was broke on a lap top and also on a home computer in another sitution. I replaced the switch and all worked well again. On the lap top the internal spring in the switch was broke and in the home computer the switch would stick. This might seem as too easy of a fix in your case, but I would sure look at this possibility first. If it's not the power switch, all the past suggestion are in order. Good luck

Remove any DVDs or CDs from the optical drives and then unplug all peripheral devices except for the keyboard and mouse. Click the "Windows" button and then type "eMachines recovery management" into the search box. Click on "eMachines recovery management" in the results list and then click the "Restore" tab. Click "Password Settings" and then type a new password into the text box. Click "OK" and then click "Restore System to Factory Default". Type the recovery password into the "Password" text box and then click "OK". Click "Next" To start the recovery process. Click "Finish" and then wait for your computer to restart. This procedure could take several minutes. Once your computer has restarted, you'll be prompted to create a new user account, enter the date and time and set up the internet settings.
or if you are running XP If you set your machine back to eMachines factory settings, it might help you for a short while but if you don't have effective virus protection your problems will return in short order.

You should get rid of this virus with an effective virus remover.

You can run Bitdefender's free online scan which doesn't need to be downloaded http://www.bitdefender.com/scan8/ie.html

If you know when you got the virus, you can do a system restore to a time before the virus was on your system.
This article tells you how to run it from safe mode http://bertk.mvps.org/html/safemode.html

Your best protection in general is a complete internet security suite such as Bitdefender or Norton internet security 2009.

If you need to totally rebuild your system and you don't have a recovery disk, contact eMachines to get one.

You might also try a Windows repair install if you have the operating system disk. Follow the directions here for XP http://www.michaelstevenstech.com/XPrepa... Source(s): http://www.ask-the-computer-doc.com/comp... Hope this helps.

http://www.geeks.com/details.asp?InvtId=D845GVSR-BO-R I would like you to 'jumpstart' it, and then post back in a Comment. Jump the Soft Power On of the 20-pin ATX main power cable. Power supply plugged into power, 20-pin ATX main power cable plugged into motherboard. Straighten out a paperclip, then bend it into a U-shape. Put black plastic electrical tape around the top of the U. Turn the U upside down. You are going to use the 'legs'. The legs go down in the back of the main power cable's connector. (Where the wires go in) One leg goes down into a socket hole with the Green wire, RIGHT NEXT TO the wire, and MAKE SURE it touches the metal terminal at the bottom. The other leg of the U-shaped jumper wire goes down into ANY socket hole with a Black wire. Contact made is brief. Does the Power Supply turn on? As stated, post back in a Comment. http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20

Is the power LED on the monitor ON, if not check the power cable connection at the monitor and at the mains.
Check the video cable connection at the PC.
Try a different working monitor on your PC and see if the monitor works on a different PC (the monitor maybe faulty).
