The fwcore.sys driver is part of the eAcceleration StopWall firewall product which is a program we wouldn’t recommend.

Removing it could be a problem. If you can, start the computer in Safe Mode and follow our instructions for removing a program to uninstall anything associated with eAcceleration.

If you are able to uninstall it, we’d also recommend running a check to remove any viruses or trojan horses.

Should you be unable to run the system in Safe Mode, you could try to use Window’s Last Known Good Configuration feature then remove the eAcceleration program.

Failing that, you may need to call your local IT support company who should be able to disable fwcore or restore the system to an earlier date.

Computer doesn’t load Yahoo Mail with graphics or hotmail with graphics(u know pretty butterfly etc) and on Facebook some of my friends pictures cannot be seen only the tiny red cross icon.

Also now pages of games I play won’t load. I have been using Trendmicro and yesterday did a Malwarebytes scan which initially seemes to improve, but today things are worse.

I tried using IE ( this is the worst) and Firefox  to see if that made a difference. Very frustrating.

This sounds like your system’s preferred program for showing images has changed. To fix this, you’ll need to select the right program as we describe in our Wrong Program Opens My Pictures post.

It could also be that your hard drive is full and Windows can’t store the images in the cache. You can free up disk space by following our Cleaning Up Your Computer instructions.

The screensaver times are controlled by the display feature settings in Windows. Go to the Control Panel, select Display and you can change the time out settings there.

On some laptops there may be differing power schemes depending on whether the system is plugged in or running on batteries, these profiles may have to be changed in the Power settings.

If you are using an Apple Mac the screensaver settings are found in the Desktop and Screensaver preferences where you can change the times to suit your needs.

The Intermittent beep is what’s called a POST (Power On Self Test) error. When you turn the computer on it runs through a set of tests before trying to load up the operating system, in your case XP.

Because the computer has found an error before the video system started, it has to use beeps to communicate what the problem is and your motherboard manual should tell you what the POST error codes mean.

Often an error like this is due to something like the RAM modules or one of the expansion cards working itself loose so it’s worthwhile getting the local computer tech to have a look or – if you’re confident – pop the box yourself and make sure all the cards are firmly seated in their sockets. Remember to ground yourself first.

It is possible to run most XP programs on Windows 7, a service for this is Windows Virtual PC.

This is a problem that came along with Microsoft Office 2007 which changed the various spell checking and document proofing functions in Windows, Outlook Express itself doesn’t come with a spell checker.

As you can see from other sites’ posts – such as Jay Lee’s Chron site and Joe Duck’s Travel Blog this has caused a lot of angst for many computer users.

You can easily fix this by downloading the free Spell Checker For OE program we describe in our Outlook Express Doesn’t Have A Spell Checker post.

There are a number of registry fixes as well that can resolve this or you can reinstall the older versions of Office proofing tools but overall the simplest solution is to add the free program.

Outlook Express, the free email program that came with Windows 98 through to XP, doesn’t come with a spell checker built in. Instead it uses the Microsoft Office spell checker.

If you don’t have Microsoft Office installed then you can use the free Spell Checker for OE to add this function to your computer.

This problem can also happen when Office 2007 is installed on a Windows XP system as the newer program disables older spellcheckers.

We’re not great fans of the McAfee computer security and anti virus products and for most Windows users there’s plenty of free options. We recommend you don’t upgrade and instead replace it with one of the free online security problems.

First, you’ll need to download the McAfee Removal tool and the free antivirus you want to replace it with. Generally Microsoft Security Essentials is the easiest of the options. We look at them at our Which Free Antivirus is Best post.

Then, once you’ve downloaded the removal tool and the replacement anti virus, disconnect from the Internet and uninstall the McAfee products by going to Add/Remove Programs and uninstalling all the listed McAfee products.

Once you’ve uninstalled the programs (you may have to reboot a few times), run the McAfee Removal Tool you downloaded earlier.

Having run the removal tool, and possibly been asked to reboot again, you can then install the new antivirus by running the program you downloaded earlier.

Reconnect to the Internet and let the anti virus progam update and scan your computer before surfing the net and downloading email.

Without McAfee on your system, you should find it running far quicker and more reliably.

There’s a number of reasons this could be happening, the three most likely are some running software – such as an anti-virus – blocking the installation, a damaged hard drive or insufficient free space on the disk.

Freeing up space on your drive is the easiest to solve problem by following our Cleaning Your Computer instructions. This will also get rid of anything in the temporary files that may be blocking the installation.

Next is checking your hard drive for problems, we cover this in our Checking A Disk For Errors post. If you do find there are serious problems with your hard drive, you may have to replace it.

Finally, it may be an antivirus or other program blocking the service pack’s installation. If you use the Windows MSCONFIG tool, you can turn off everything that starts with the computer. Take a note though of what you do turn off.

Updating your computer, whether you have a Windows or Mac computer, is very important as new security bugs are found all the time. Unfortunately Microsoft’s automatic update function can be intrusive.

It isn’t a good idea to totally disable the Windows Update service as those updates and patches are important, but you can change the settings so they are downloaded but not installed until you choose to do so.

Microsoft’s Knowledge Base describes how to change the Windows Update Settings, we recommend the download updates but let me choose when to install themoption.

One of the delights of having a decent junk mail filter is you never see the dozens of pointless emails that arrive in your inbox each day. So when an update damages your spam filter it’s a real irritation.

The repair for this is actually quite straightforward, go to the Control Panel and select Programs in Windows 7 or Vista or Add/Remove Programs in Windows XP , click on Live Mail Essentials 2011 and select Uninstall/Change.

In the wizard that then starts select Repair all Windows Live Essentials Programs, the repair may take some hours and require a working Internet connection.

Once it’s finished, you’ll be asked to reboot the computer and the problem should be fixed after the restart.
