How can you remove traces of old, unwanted junk files from your computer?
Have unwanted junk files on your computer that you want to get rid of for good? My advice would be to get CCleaner!
CCleaner is a system optimization, privacy and cleaning tool. It removes unused files from your system - allowing Windows to run faster and freeing up valuable hard drive disk space. It also cleans traces of your online activities such as your Internet history. Additionally, it contains a fully featured registry cleaner. But the best part is that it's fast and FREE!

Why is my internet speed coming slow on my pc while high on my friend's pc?
QUESTION:
Me and my friend have same plan. I have windows xp and he uses linux.I get max 300 kbps while he gets 500 kbps. Why does this happen? Will i also get 500 kbps if i shift to linux operating system ? Why does linux operating system get more speed?
MY ANSWER:
There are a large number of variables imbedded in your question that can make all the difference.
You mention ‘plan’ – so I assume you are on the same carrier but different addresses, modems etc. could also be a factor.
First, I would assume different addresses, same carrier with identical PC hardware, and you are basically asking - is Linux faster than Windows XP?
- Also, I would have to assume from the speed quoted that this is older, residential DSL
- Also, from the way the speed was quoted I would have to assume we are talking about raw ‘apparent’ file download speed from the web.
- Another element of this scenario is just because the plan quoted by the carrier says 500k doesn’t make it so.
- So…back to the core question is Linux faster…YES…but what are you going to do with it???
- What exactly does the speed listed mean to you – how do you use it - - for email with average attachments and browsing ok.
- Where are you going to get applications – Linux support is not universal – commercial programs exist but are not free. Basically, I think that if this is an actual ‘measured’ case that you would like to troubleshoot further as opposed to a hypothetical Linux vs. WinXP question. This is then a question of why is my modem/connection to my ISP running slower? If you are at a different address, different modem, PC of different config etc., then you have many variables. And for the speeds listed, and assuming an up-to-date PC (QuadCore / i7), then this is not a windows issue, but an ISP issue.
Need to reboot with a diskette I no longer have...
What can you do when a computer tells you to reboot with diskette, but you no longer have the diskette?
In a computer forum I frequently post to, I read a question from someone that turned on their computer only to read a message "reboot with diskette," which this person no longer had.
My response:
My first answer to this is that your hard drive has gone kaput. Unless it is an ancient DOS system, you probably don’t even have a diskette drive. Even if you do now-a-days, most systems boot from the CD/DVD drive. Depending how “kaput” your hard drive is will depend on how much data you have lost or how recoverable your system is.
If your system is Windows but also a much older one, your CMOS battery may be dead which means that your hard drive “may” be ok but the system doesn’t recognize any of the internal hardware. This is a much cheaper fix (if that is the problem) by changing out the internal (probably 2032) battery.
Is My Wi-Fi Security Good?
The Question...
"Im using WPA2-PSK
(AES) security for my router with randomized 25 character passcode and MAC filtering for it to. I always get wierd feelings that someone is still using my internet despite this. My internet gets slow and will disconnect every couple of days, is it supposed to do this? or could someone be using my internet? Is there a way to check to see if someones using my internet? I know you can check the attached devices but i feel like someone has bypassed it. What else can i do to protect it?"
My Answer...
Your already are using a high level of security but one further step is Mac list access – if your machines MAC address isn’t in the list (that you control by password access from inside the network) there is no wifi access- - unless you’re in an apartment/condo or under the same roof as this would-be-internet thief, then the quality / usability of this link at a distance is very poor. If there is that much concern over snooping – than don’t connect any
computer with important data to that network at all – use a separate router and keep things separate. If that’s not enough turn your wifi off and use a long CAT5 cable. From a non-technical standpoint, let me say that anti-spyware can do this to your system also. There is no way to be fully protected no matter what you do. You can have as many locks on your door as you wish, but as long as man makes them, man can break into them. This is the same with Internet security. Realize also, that if you have a cable connection or FIOS, your system is susceptible to outside access when it is powered up - you don’t have to be on your system.

Networking Tip/Troubleshoot
Can connecting another computer to my network influence the connections of the other computers?
I had a scenario where a client had two computers both connected to a wireless router. They connected a third computer to the network and, although the connection went through for this new computer, one of the original computers now says "limited or no connectivity" and cannot connect to the Internet. The question was is it possible that the new computer is using up too much bandwidth and is therefore preventing the other computer from accessing the Internet?
My Opinion...
Hooking up many computers to the same network can slow down the computers....all of them at the same time. Normally you would not notice the slow-down speed as it is in Mhz. However, it would take many more computers than three to slow it down and the error message is not due to any slow-down.
The first thing I would check is the IP address on the third computer and the computer that is not connecting fully to the Internet. The IP address is an address assigned to each computer so that the wireless router "knows" who it is "talking" to at any time. The IP addresses MUST be individualized.
The second thing I would check is for viruses or spyware on the computer that is not connecting to the Internet. The first thing most spyware does is disconnect the connection to the Internet so that you cannot easily uninstall it.
HOW TO TAKE MY PASSWORD OFF MY COMPUTER...
This could be simple or hard, depending which password you want removed/changed. Yes, there are two passwords on your system!
If you are simply talking about your user password, i.e. the one you log on with, then go to Control Panel and Users (the actual path to get here is different for each type of operating system). Under there is the ability to edit your password. If you don’t want a password, then just leave the new password blank.
If you are talking about the administrator password, i.e. the one you need to make changes or log into the deeper bowels of the system, that can be changed one of two ways. First there is a set of pins on the motherboard that you can short out erasing the system’s memory of the password. Second a good techie may have a program that can change/erase this password. This is not something the standard user should get involved in.
Laptop Overheating/Shutdown
Did you know that when laptops get over-heated, they will shut down. The most common cause of over-heating with a laptp, from my experience, is that the internal fan is clogged with hair, dust, dirt, etc. Someone would have to take the laptop apart and dig all the "garbage" out of the fan.

When to Ditch and Buy New...
So you recently upgraded to a new laptop. You have an old laser USB mouse that you would like to use. After all, why buy when you have what you need, right!? You find the USB mouse works, but not great. You hear Windows dinging every couple seconds because the USB unplugs, plugs, unplugs, plugs.....
My advice:
Since the price of a new mouse is 10 or 15 dollars, I wouldn’t spend more than 2 minutes working this old one. Time to ditch and buy new!
Laptop Won't Connect to Router...
What to do when your laptop will not connect to your router, but all other systems in the house will. Here are a couple things to try as a start....
1. Unplug the router for one minute. Then plug it back in and give it time to "find" itself and set up the network (about 1 or 2 minutes). Then try logging back on.
2. If that doesn't work, then you would need more information. Your laptop was once connected to the Internet, but now it's not, so what was done to it since that time? What model laptop is it? (ie, do you have a wireless switch turned on or is there a combination of keys to hit to activate the wireless capability of it?) Have you run anti-virus and anti-spyware against it? One of the first things spyware will do will disconnect you from the Internet so you can't clean them up.
This is just a start of the basics for solving this issue. Good luck in your troubleshooting! If you need, or would like, further info, send me an email at
