This might be a browser or browser plug-in or some program which is running wild. Running Task Manager (from the ctrl-alt-del menu) and sorting the display on the CPU column will indicate whether a particular program is to blame. Speedfan is useful for showing internal temperatures. Cleaning the fan and air filters is required. If the computer is overheating (often indicated by the fan running continuously) it may be that the CPU speed has been automatically reduced to limit heat output. Always download programs from the developer's own or recommended site, and be very careful of pre-checked tick boxes offering additional 'recommended' software or toolbars which are very rarely worth having. Steer clear of these sites, and any sites which require you to install a 'download manager'. PUPs are often installed by download sites, from which they make their money. Antivirus software (if installed) may show it up as PUPs (Potentially Unwanted Programs).

If the computer is plagued by pop-ups then this is a strong indication of malware, or at least some very undesirable programs. Check online for the computer's user handbook if it's not to hand.) (For example, it might be acceptable to add a 1GB module (1024MB) to a 512GB module, but not to a 256GB. (More than 4GB is simply wasted on a 32 bit operating system as it has no way of accessing it.) Upgrading memory is easy, but you must make sure you use the right type, and that more than one module form an acceptable mixture.

Windows XP needs at least 512 MB and Vista or later should be given at least 1 - 2 GB. You should make few simple observations and tests before engaging on a 'deep dive'.Ĭheck how much RAM installed. There are a few key things that are well worth trying before giving up on your trusty PC or Windows laptop (and many of these will work for Macs too), but before you attempt anything, it’s vital that you back-up your files. Many of these will make little difference and some may make the problem even worse or install unwanted programs. There are plenty of suggestions online, as well as paid-for products, which claim to fix slowness. Probably the most common reason people ditch their old computer and buy a new one is not that the old one is broken in any way, but that it’s simply running slowly.

Consider anti-static precautions when handling RAM or deep disassembly, especially when humidity is very low, or at least touch an earthed metal object before starting. Before doing anything, it is vital that the user's data is backed up.
