Double dose of AV?

Q: Should I run more than one anti-virus program?

A:Short answer: no.
Long answer: Anti-virus software to be effective must hook in to the deepest levels of the OS and even modify how the system works. Often employing the same techniques root-kit and Trojan programs do to secure control. So having two applications competing for supreme dominance over your PC is not a battle you as a user want on your computer. I humbly suggest installing AVG Anti-virus or NOD32 and using an on-line scanner like Housecall for a second opinion.

One other note. Stay away from Internet Security suites from any vendor. They are always bloated and ultra prone to conflicts. Unless you are a Slowsky turtle slowing the PC down in general is not a good thing.

Access point cage match.

Q: I have a cable modem connected to a Linksys router for internet service. I am trying to connect 2 Linksys access points to the router in order to provide wireless internet to opposite sides of the building. I can’t get both access points to work at the same time. Whenever one works the other will not. The access points are not where they can communicate with each other. Any ideas why they will not work at the same time?

A: Their are two sticking points I see with the network you describe.

  1. Too many cooks. DHCP or Dynamic Host Configuration Protocol allows the devices on your network to request and obtain an IP address from a DHCP server. Linksys routers and some access points have built in DHCP services to make network setup easy. Unfortunately for you if you have more than one DHCP server conflicts will occur. So look up DHCP in the admin panel of each access point and disable the DHCP service if it exists.
  2. Same address. Just like every phone needs a unique phone number. Each device on your network needs a unique IP address. So you need to statically assign each access point its own IP address
    • Plug in the first access point
    • Access it via its default IP address of 192.168.1.245. (Remember that the default password for Linksys equipment is “admin”, with no user name.)
    • Simply changed the last number of the IP address to 246
    • After you save the changes you should be able login to the access point again via that new IP address. In this case, 192.168.1.246.
    • You can now plug in the second access point without conflict.

This would be a good time to enable WPA encryption. More on that later.

iTunes store is iSlow

Q: I am having a hard time accessing iTunes store. It takes forever to connect to iTunes and then sometimes it cannot connect. Surfing the web is fine. No delays.I really do not know what to do.

A: First thing to try is deleting / cleaning out your internet cache and temporary files. Sometimes iTunes gets lazy and refuses to clean up after it’s self. This also helps if you suffer from a BSOD (blue screen of death) every time you plug in you iPod.
Another solution is to uninstall iTunes completely. Don’t worry your music will remain untouched and safe. Download the latest version of iTunes from apple and reinstall it. iTunes Download

If you go the uninstall reinstall route you may have to renter your iTunes store credentials afterward.

My pc keeps turing off.

Q: My pc keeps turning off after about a minute. Then I see a RGB error. What should I do?

A: First the RGB error your seeing is likely just the monitor letting you know that it’s not receiving a signal from the PC. Because the PC is off it can’t send a signal. So no worries there.

If the PC is going through its shutdown process after about a minute of operation you might have some malware on your system.

If your PC is snapping off as if the plug has been yanked from the wall my first thought is a bad fan. Your PC creates a lot of heat and heat can build up very fast and even cause damage. With out fans modern PCs get very cranky.

You should open up the case and get a flash light. This also might be a good time to grab a can of compressed air and (use short bursts with the PC unplugged) blow out any dust buffaloes you find inside the case.

Next power on the PC and look around inside to see if all the fans are spinning. Be sure to check the fan on the back of the power supply. Be very careful not to touch the inner workings of the PC while it is powered on. Electricity bites very hard.

When you find the dead fan replace it with a new one of the same type.
