IT Queries: Computer problems answered

I notice you advertise companies that provide registry cleaners on your site. I used a uniblue registry cleaner on my small notebook and it completely destroyed the operation of windows. I was able to recover normal operation through system restore. I would like to keep my computers running quickly and efficiently. Do you recommend the use of registry cleaners. I have Windows XP on both our laptops, Dell and Fujitsu.

The short answer is that we don’t recommend any registry cleaners as most are snake oil and the benefits of running a registry cleaner are not that great for the majority of Windows computers.

We discuss this in more detail, along with why we don’t recommend registry cleaners on our registry repair tools page.

Overall, save your money and time.

In regards to the adverts on the site, they are provided by third party companies and we unfortunately don’t control every advert that appears.

I have received a fraudulent email from a bogus UPS parcel delivery site. As I have been expecting a delivery, I mistakenly opened the email and clicked on the attachment.

My AVG 9 program promptly detected 2 viruses which I thought I had then successfully removed. However now, when I boot up, I get the following 2 error messages:
C:\\WINDOWS\\rhstap.dll – Specified module could not be found
C:WINDOWS\\olamobel.dll -Specified module could not be found

1. Does this mean the registry is damaged?

2. How can I repair the registry and avoid getting these error messages … can you recommend a safe registry repair tool?

It’s good your antivirus picked up the problem and removed the malware. Just to be safe, we’d recommend following our Removing a Trojan instructions as well.

Once you’re happy you’ve cleaned the computer out, you can fix the missing .dll issues. The registry itself isn’t damaged, it’s just trying to find the files the malware installed and told it to run on startup.

The best tool for cleaning out the errant registry entries is CCleaner and running that after making sure you are free of viruses should give your computer a significant performance boost.

Would it be possible for me to install a new video card in desktop pentium 4 cpu 2.66ghz windows XP? The system shuts down then shows message thread stuck in device driver.The video card is nvidia gforce.Thanks.

It would be if you could find the right card, which in the case of this machine is probably an AGP card. The problem you will hit is finding a card is going to be expensive as these aren’t common any more.

You may find replacing the card isn’t necessary and it’s a software driver problem. This can be fixed by booting the computer into Safe Mode, deleting the existing video card drivers and copying the latest software across.

This isn’t a simple task though and it’s best done by a computer technician. You might want to speak with your local tech or computer store to see what the options are. It may be replacing the computer is a more cost effective option.

Hi Paul,
Unfortunately you had run out of time on the excellent radio program last night when I called. Wondering if you have any idea what has suddenly happened to my pc, XP o/s, HP9002.
1. All of my Inbox in Outlook Express disappeared. The 400 emails had been sent to the Deleted folder. This always happens when I first go in to Outlook
2. The Delete keyboard key no longer works.
3. When I click on the task bar Start menu a pop-up asks me if I want to send the Start Menu to the Recycle bin. This only seems to happen intermittently.

Hope you can help.

This certainly is very suspicious behaviour and the first step would be to follow our Removing a Trojan instructions. Before doing that, make sure all your data has been backed up.

Both free versions of AVG and Avast! are good programs and you should use whichever one you find easiest to install.

If no malware is found, it might be best to have a technician look at the system and your security settings.

I am using windows XP. I am on Microsoft Outlook for my email and I have gmail as my default email.

What should i do? should i go to control panel, firewall, and go to advanced and press return to default? i am scared to as it said some things could be lost. I think at some point last week I pressed a button somewhere saying ‘reset’ but i can’t remember what i did . thank you so much.

Email error 554 really doesn’t tell you much except the message has been rejected by the recipient’s server. It could be for any of a number of reasons which could lie on your system, your Internet provider’s servers or a problem at the other end.

One common problem is time and dates. If the clock on your computer is seriously out, then some servers will reject emails sent from it. So checking your computer’s time and date is a good first step.

You should also check your return addresses are correct; for instance if you are sending out emails saying you’re with AOL when you are really with Comcast will be another reason for servers to reject your emails.

If the problem continues, call your Internet provider and get their support line to walk through your email settings to ensure they are correct. Beyond that, the problems are either with the various mail servers or your ISP.

I have many things that appear twice or more in my add or Delete programs file.Why is this …J2SE Runtime three times.

What is all this stuff and do i really need it all taking up space on my hard-drive…. Grateful for any intelligent but simple language reply Thanks

Sometimes Windows programs don’t behave as they should and you get multiple entries but in this case, it appears they are legitimate programs. Java is particularly notorious for leaving older versions on your computer.

The first thing to do is to run the Windows Installer clean up tool which we’ve described in an earlier post. This will clear out any problems.

For programs like Java which have installed multiple versions, it’s probably best to uninstall all of them then download and install the latest version from the Sun Java website.

In the case of the Windows Updates, these are best left alone as they are specific fixes for known Windows problems. Should Microsoft release a Windows XP Service Pack 4, then it may be worthwhile deleting these before installing the new upgrade.

The Visual C++, we don’t know. Do you have a programmer in your household? If so, best let them deal with it or leave the program alone.

Otherwise, it’s best to delete anything you don’t use often. However the general rule with computer is “if you don’t know what it does, then leave it alone” and that certainly applies to your Add/Remove programs.

What is indexing?

Indexing is noting the names and contents of files so it’s easier to find them later. It’s like the index of a book where you can quickly look up which pages a word, name or phrase appears rather than reading the whole book.

In the computer world and on the Internet, indexing speeds up looking for things as the process of searching through millions of websites or folders for your search would be painfully slow.

On Windows computers, there is the Indexing Service which was designed by Microsoft to speed up search. Unfortunately it never really worked that well and we recommend disabling it.

Overall, Indexing is a good thing as it makes life easier for us in the Information economy. It isn’t foolproof though and if it’s poorly done it can cause problems.

I have a new computer running Windows 7 and I can’t figure out how to copy the addresses in Outlook Express on my old computer to the new system.

You’ll have to export the old address book into a Comma Separated Value file (.csv) on the old computer, copy the CSV file across to the new computer and then import it into Windows Live Mail. It isn’t complex, but it is a bit fiddly.

First, open Outlook Express on your old Windows XP, ME, 98 or 95 computer and choose Addresses on the tool bar as show below;

Once you are in the Windows Address Book choose File then Export and Other Address Book.

In the Address Book Export Tool, select Text File (Comma Separated Values) and click Export;

The program will then ask you where you want to save the CSV file, choose an external drive which you can plug into the new Windows 7 computer or, if both the computers are networked, a location where the Windows 7 machine can find the exported file.

Once you’ve saved the file go to the Windows 7 system and plug in the external drive if you’ve used that to save the CSV file.

In the Windows Live Mail screen, select the contacts button and show menu, then choose import and Comma Separated Values. The program will ask where the CSV file is, and you’ll need to tell it where the file has been saved.

Click continueand the import process will start. During the process, the program might ask you about field mapping, this is where the computer isn’t sure which part of the file belongs where, so you may have to tell the system which part is the email address, which part the surname, etc.

Once you’ve completed, you should find all your addresses have come across. Keep in mind if you have multiple address books or groups within the address book, you’ll have to recreate these.

When ever I try to open anything in windows media player it freezes the computer and the only way to do make it respond is to shut down computer with power button on computer.

The first thing to do is clean up your computer as it may well be something lurking in your temporary files which is upsetting Media Player.

Should the problem continue, you may have to reinstall Windows Media Player. Open the Control Panel and click Add/Remove Programs, or Programs in Windows Vista, and select Internet Explorer.

To right of the selection there are two buttons; change and remove. Click the Change button and follow the wizard to repair the existing installation.

I bought a Mac because I was fed up with my kids infecting the family computer. Now I’m reading Macs may be more vulnerable because virus writers attack popular computer systems. Is this true and should I get an anti virus for my Mac?

The short answer is “no”. The “big target” story is peddled by people who either have no understanding of computer security or have an interest in selling anti virus software.

In reality the bad guys go for the easy targets and in the world of computer security there’s no easier target than Windows.

In a recent Security Intelligence Report, Microsoft pointed out the first version of Windows XP was by far the most susceptible to viruses. This was due to lousy security (the built in firewall was disabled in XPs early versions) and countless security bugs.

But the main reason for Windows being the malware writers’ favourite operating system is Microsoft’s decision to let Windows users run as Administrators with full control over changing system settings and install software.

Most other operating systems, including Apple OSX, insist users run in without the ability to change system settings.

This fundamental flaw leaves most Windows users wide open to malware infections. Virus and spyware writers just have to get access to the machine and simply visiting a website offering free games, pornography or music lyrics is enough to get many systems infected.

While it is important to take security seriously on all operating systems, including Linux and OS X, by making sure you update security patches and keep your system behind a firewall, Windows has the biggest problems.

Don’t be panicked by ignorant or dishonest advice.
