Published by & filed under Misc Software. Last updated .

Microsoft have now updated their free anti-vir­us to ver­sion 1.0.1500 which is avail­able from win­dows update if you have the pre­vi­ous ver­sion installed (see [int­link id=“10” type=“post”]my pre­vi­ous post[/intlink]). If you want to install 1.0.1500 without installing the old ver­sion first it can be down­loaded from Microsoft. If you’re in a coun­try where its unavail­able then you can down­load it from Soft­Pe­dia

0Ultrabook logo laptop vaio sonyRepair HP Laptops and other hardware cheaply

Published by & filed under Misc Hardware. Last updated .

I was recently asked to look at the touch­pad on a HP Pavil­ion DV2000 laptop which had a faulty left but­ton. Spares and repairs for laptops are often hard to come by so I was pleased to find the HP Ser­vice manu­al as a PDF, which included all the part num­bers, and then very pleased to find that HP offer an extens­ive dir­ect sales ser­vice for most parts via the HP PartSurfer. Suf­fice to say this laptop is now fixed, for a very low price. Good move by HP — I won­der if oth­er major man­u­fac­tur­ers provide a sim­il­ar service?

0Google Earth LogoGoogle Earth: How to fix poor quality overlays

Published by & filed under Misc Software. Last updated .

I’ve recently had some prob­lems with dis­play­ing large over­lays (gen­er­ated from NASA SRTM data) in Google Earth. Although the over­lay data I expor­ted was very detailed google earth was dis­play­ing a blurry mess which was imprac­tic­al for my inten­ded pur­pose. Search­ing around on the ‘net did­n’t reveal any­thing use­ful so as a last resort I tried switch­ing from “Dir­ect X” to “Open GL” mode (under tools: options).

0NoScript logoImprove your browsing security without crippling lots of sites

Published by & filed under Web Technologies. Last updated .

I always recom­mend that people install an altern­at­ive browser to Inter­net Explorer. Per­son­ally I prefer Fire­fox to the oth­er altern­at­ives (Chrome, Opera, Safari) as I find the huge num­ber of addons on offer give it an unas­sail­able advant­age. I’ve recently exper­i­mented with the NoScript addon, which enhances secur­ity by block­ing act­ive objects and scripts unless expli­citly approved. How­ever I found that I was forever hav­ing to grant per­mis­sion to every site I vis­ited for it to work correctly.

0Serial Key LogoReplacing an invalid Win XP key with a genuine key

Published by & filed under Misc Software. Last updated .

If you’ve ever been asked to fix a PC and have sub­sequently dis­covered it has a non-genu­ine or inap­pro­pri­ate Win­dows XP key installed, and you wish to update the key with a legit­im­ate key, for example when a second hand laptop has been installed with a cor­por­ate key and needs updat­ing with the OEM key from the stick­er still attached to it, you may have run into prob­lems switch­ing between OEM, Volume and Retail ver­sions of windows.

0Microsoft Security Essentials LogoFree Anti-Virus from Microsoft

Published by & filed under Misc Software. Last updated .

Microsoft have released (a few weeks ago) a free Beta of their new Anti-Vir­us / Secur­ity product Microsoft Secur­ity Essen­tials. Unfor­tu­nately as a UK res­id­ent when I vis­it the offi­cial Microsoft page I am told “This beta is avail­able only to cus­tom­ers in the United States, Israel, China and Brazil”. A quick google search quickly turns up a down­load link on Soft­Pe­dia which works. There are down­loads of x86 and x64 ver­sions of Secur­ity Essen­tials for Win­dows XP, Vista and 7

0AMD Radeon Graphics LogoInstalling Mobility Radeon drivers from ATi

Published by & filed under Misc Software. Last updated .

Update: Cata­lyst Mobil­ity drivers are now avail­able for many cards from ATi. (as of Cata­lyst ver­sion 10.3)

It seems to be very dif­fi­cult to obtain reas­on­ably up-to-date drivers for the ATi graph­ics chips in many laptops. This is because the OEMs have asked ATi not to provide gen­er­ic drivers dir­ect to the end user, ostens­ibly to reduce sup­port requests from users with drivers not tested by the OEM’s. This seems per­fectly reas­on­able, but the sad fact is most OEM’s only update the drivers for a new laptop mod­el a few times and soon aban­don it as they con­cen­trate on the next gen­er­a­tion release. For those people try­ing to update their drivers to address a prob­lem or to gain access to new fea­tures there are no clear options. For­tu­nately there are ways around this problem.

0PC Hardware CPU RAM UpgradeDon’t use too much TIM!

Published by & filed under Misc Hardware. Last updated .

A quick note of warn­ing about apply­ing Thermal Grease / Heat­sink Com­pound to CPU’s. Don’t use loads! Not only will it not work very effect­ively, if you really go over­board it can leak over the sides of the cpu and get under­neath as it has in the image. This CPU (A pen­ti­um 4) was giv­en to me as “I think its broken”.
