Can I upgrade the Ram in my Dell Dimension 3000from 512MB to 2GB?

Q.

I have a Dell Dimension 3000, and it has 512mb of RAM, I want to install a 2gb ram but it only has the two slots which are full can i replace one with the 2gb RAM?

A.
Probably not – Dell motherboards are notorious for not working well with mixed RAM sizes. Your best bet is to buy a 2GB (1GB x 2) kit from Crucial.com, remove the RAM you have, and install the kit RAM. Not only will you have 2GB (which is plenty for almost anything a Dimension 3000 is capable of running), but having 2 matched sticks installed will allow for running in Dual Channel mode, which will increase memory speed overall. When purchasing the kit, look for 1) a lifetime waranty, and 2) the lowest CAS timing numbers, and 3) the highest speed (Mhz), in that order.

Is there a way to improve my CPU speed for this game?

Q.

I just bought a new PC game and I ”accidentally” kinda rushed and bought it so I didn’t take time out to check the minimum requirements. The problem is my computer runs at 1.6 GHz and the game requires 1.8 GHz..now the game runs but, really slow…. I don’t need any scanners or clean-up programs. Nothing is wrong with it besides my CPU speed, ”which I want to speed up”…I already know my computer is fine no virus’s or any useless files taking up room, its brand new…..period. I just wanna know if there are any overclocking software, or something close to it that I can use…

A.

If it’s a new PC, and it’s 1.6Ghz, I’m going to go ahead and assume it’s a low-end laptop or netbook. There is really no way to improve the CPU speed, but that’s not likely the issue. Most low-end laptops, and almost all netbooks, use an Intel integrated GPU (graphics card), usually the i945 or i965 chipset. Neither is suitable to playing 3D games, or any game that has a lot of graphic motion. Unfortunetly, in the case of a laptop or netbook, there is now way to fix this – they just really aren’t made for playing graphically intensive games.

Strange beeping noise from my Macbook superdrive.

Q.

I had just gotten a new game for my Macbook, and it usually plays fine. Although sometimes when I insert the disc, my CD drive makes a really loud “beeping” noise. It isn’t like a electronic type beeping, but it definitely comes from the CD drive. It’s hard to explain. It beeps about 4 times per second maybe for about 10 seconds, stops and the CD drive makes a few sounds like it’s loading, then starts again. Sometimes after that it ejects the disc. While this is all happening, it won’t read the disc or put that icon on the desktop that shows a picture of a disc and what the disc is. What is wrong with my superdrive? Do I have to get it replaced? Also, if I try to eject the disc while it’s doing this, it takes around 10 seconds. Which is way longer than normal.

A.
They sound you are hearing is from the head control motor in the drive – it’s so small and quick that the sound really does sound like a beep. I’ve seen (rather heard) this many times. The short answer is, the drive is going bad. Replace it and all should be well. This is something you can do if you can use a screwdriver – they’re very simple to replace.

Network controller not found after reinstalling Windows.

Q.

So I had a virus and I reinstalled Windows on my laptop after clearing the hard disks, only to find that I lost my network controller, now I’m clueless..the troubleshoot is useless, telling me to plug in an ethernet cable when it is Wi-Fi Capable…where can i get the drivers? It’s a Toshiba laptop and network adapter is a Realtek PCI Family, something along those lines. What do I do? Thanks in advance!

A.

It’s very common for this situation to occur – most Windows disks that come with a PC are “just” Windows, they don’t contain any of the required drivers for the PC’s hardware. You need to download the drivers from the manufacturers website (in your case Toshiba). For this, obviously you’ll need a working Internet connection and a way to transfer the software. A USB flash drive and your local library are your friends in this instance. Just make sure you have the model number and serial number for the laptop – they can be found on the backside.

Be prepared to find several different drivers for hardware – a laptop (or any computer really) will often have drivers for multiple devices that may or may not actually be in the model you have. Best bet – download them all, try each one – they’ll either work or won’t. Make sure you grab ALL the drivers – mouse (trackpad), sound, video, modem (if it has one), wireless adapter, ethernet adapter, etc…

Problems booting Windows after an Ubuntu uninstall.

Q.

I accidentally uninstalled Ubuntu from my computer by deleting the partitions. Now, whenever I boot up the computer it says error: no such partition grub rescue> I think I might have deleted grub along with Ubuntu and now I can’t get Windows 7 to boot! Does anyone have any solution to the problem?

A.

What you have done is essentially removed Ubuntu, but left the boot loader (GRUB) in place, which is still looking for the Linux partition(s). If GRUB is still functioning, and was the primary bootloader, you can (usually) hold the “Shift” key while booting, which will bring up the GRUB boot menu, and allow you to boot into Windows. If Grub wasn’t the primary bootloader, or if it is damaged, the other option is to boot the computer from a Windows install disk, drop to the command prompt, and run the commands “fixboot” and “fixmbr”. This will reset/replace the bootloader with the Windows bootloader and allow Windows to live again.

Another option is to reinstall Ubuntu again, which should offer you to set up the bootloader as before.

Windows 7 or Windows XP, which is better for this computer?

Q.

My system specs: Intel Pentium 4 @ 2.8 GHz 2GB of DDR2 Ram @ 800MHz Nvidia 7100GS graphics card 5400rpm Hard Drive I have both (64-bit)operating systems but I don’t know which one is best. The ONLY thing this computer will be used for is Mozilla Firefox and Windows Media Player. Things to consider are: Boot time Hardware Acceleration(for Mozilla and WMP) CPU usage Usability(This is my moms computer) Most Future Proof. I can do tweaks to both systems which will leave Win 7 using only 700MB of Ram and XP using only 250MB of Ram. I will also adjust the video performance. Thank you for all your help.

A.

A computer with a P4 2.8Ghz and 2GB of RAM will run Windows 7 quite nicely. Boot times will definitely be better than with Windows XP. Windows 7 is the “defacto standard” for most newer hardware, so as far as “future proof” goes, Win7 is the answer. If there are any programs that actually “require” XP (older software), a better option than using 2 partitions is to use VMWare and run XP inside of Win7. VMWare is free, and works wonders in this situation. Multiple partitions, dual-booting, and “inexperienced” users = constant headaches.

Will using one stick of RAM in a motherboard designed for dual channel work, or do I need 2 sticks?

Q.

I have one 4GB RAM stick on me but I was wondering if I need to buy another identical one or if I can just run that single ram stick in the slots even though they are designated as dual channel?

A.

You can use just one stick of RAM is a motherboard designed for dual channel operation, but if you get another, you need to match it (CAS/RAS, timing, and size/layout, i.e. 4×64) for the dual channel functionality to work properly.

Will my computer overheat with these specs?

Q.

I have just bought a new CPU (AMD Athlon II X3 445) with its stock heatsink and fan along with a new motherboard (got a package deal). I have installed these in a really old eMachines case which used to have an ancient P4 1.7Ghz processor (its like a Ford Escort with a Ferrari engine in it). Now its running nicely and theres no problems whatsoever. However I’ve just ordered an ATI Radeon 6950 1gb graphics card along with a 650w power supply and I’m going to be putting that in next week. The case I’m using can fit it all in fine but has no fans in it, however I’ve been leaving the side of the case off and at the moment the CPU temp only seems to get to about 45c max. However will this still be OK for the GPU (PS I don’t intend on overclocking either the CPU or GPU) if I start playing games?

A.

Chances are, it will probably be fine as is. Most motherboards that use AMD CPU’s also have the Cool n Quite option, which will regulate CPU speed based on heat. My suggestion would be to spend a few bucks on a 5.25” bay fan and install it in the uppermost 5.25” bay (CD/DVD drive bay). Most eMachines cases have 2 5.25” bays, so this should be no problem to fit it in. There are also exhaust fans that fit in the slot bays (where video cards, sound cards, etc.. go), and will work well along with the 5.25” fan to provide enough airflow to keep things cool.

Why is my computer background blue again?

Q.

About a month ago, I went on newgrounds.com and after a few minutes my computer said it had viruses and then my desktop wallpaper turned blue. In big red letters it said “WARNING”, and some other stuff about how everything I do is saved in my hard drive and can be looked at by forensics and my family and can ruin my life. I found out it was just a scare tactic from a spyware company, but it was still pretty scary. Anyway, my screen went back to normal within a few hours. My friend who told me about newgrounds said it shouldn’t have any viruses because every time she goes on it, nothing happens. So here I am a month later, in the same situation. Should I do something about this or should I wait like last time? Is this more serious than I think? I don’t want to buy anything, especially if I don’t need it. Has this happened to anyone else, and if so, what did you do about it?

A.

First off, if the same thing keeps happening, you need a better Antivirus / Antispyware software, whatever you have is obviously not working well. The problem is, the PC is already infected – realistically (and unfortunately), your safest option is to back up your data (pictures, music, documents, etc..), and reinstall the operating system.

Virus’s and spyware can be thought of like nails in a tire. When you get one, you don’t go back down the road trying to find where it came from, you just get it fixed. When you run over 50 nails, you don’t try to patch the tire, you replace it. Then, you stop going down that road. Virus’s and spyware in Windows is the same deal – sometimes it’s impossible to fix a badly infected OS, it just needs to be wiped out and reinstalled.

Update: Newgrounds.com seems to be an autoblog of sorts, just pulling information about games and reposting it. I doubt the site itself is the problem, more likely some of the games it links to are coming bundled with some type of spyware. Rule #1 – Nothing In Life Is Free, ESPECIALLY ON THE INTERNET – you’ll pay for it one way or another, in this instance, by having your computer infected…..

What’s the best way to link two computers to one modem, without using a router?

Q.

My brother works at home and uses a VPN and needs to be directly plugged into the modem, making the router useless. This sucks cause that means I can’t use the Internet while he’s working. Is there any two ported modems or anyway to both use the Internet at the same time?

A.

The router is not useless, it just needs to be set up with port-forwarding to direct the VPN traffic directly to his PC. If he’s using VPN, I would assume there is some type of tech support at his company that should be able to give him the information required to set this up.

If not, another option is using an Ethernet switch – it’s the Internet equivalent of a phone line splitter. As long as the modem supports DHCP (which most residential Cable and DSL modems do), this will work just as well.
