I have some games for PC and I recently noticed that they are slowing down and lagging. I would like to know what hardware for my PC would I have to buy to speed my games up?
In My Computer, right-click on C: and select Properties. Then select Disk Cleanup. I would uncheck the Disk compression option, but you can leave the other options checked.
Then on the Tools tab click Error-checking -- Check now and Defragmentation -- Defragment now.
I also recommend downloading the free utility CCleaner. Install it and run the registry check. Select Fix all errors.
In terms of hardware upgrades, adding RAM is usually the best bang for the buck. If you are talking about graphics intensive games, obviously a more powerful video card helps. Faster processor or upgrade to dual or quad core processor speeds things up.
Every time you install and uninstall software on your computer and surfing online you create junk in the computer registry.over time, the registry can grow to enormous proportions, especially if the various programs you've installed do not do a good job of deleting and/or updating it's Registry entries.You need to scan and clean your computer with registry cleaner to make it fast.Good Registry Cleaner will improve your computer and Internet performance dramatically!

The single most important piece of hardware you need to be looking at is a new graphics card as it's going to be the biggest bottleneck in 3D games. If you're PC has a PCI-express slot ( it should if your PC is from 2004 or later) then you're in business because ATI just launched their Radeon 4800 series recently and the 4850 model is the best sub-$200 card to come out in a long, long time. It will play almost any game out today as long as your CPU isn't archaic (Pentium 3 or earlier).
If you're PC doesn't have a PCI-express slot then it may have an AGP slot (advanced graphics port) which is an older graphics interface that is not even technically supported anymore today. If this is the case, you're still in luck because unlike Nvidia, ATI was great about supporting the AGP interface as long as they could. Only their latest and greatest cards have dropped support for this interface which means you can still find a Radeon 3850 AGP card for $130 or so without much trouble. It's a very good card that should improve your frame rate in 3D games substantially, especially if your using integrated graphics at the moment.
Installing either card is a simple task that anyone can do. If you have an older Nvidia or ATI card already installed you need to go to add/remove programs in the control panel and uninstall the driver. After that open up your case and unplug the old card and replace it with new card. Boot up windows and place the included disc into your DVD/CD ROM drive to install the drivers and software. After rebooting once your new card is ready to use.
If you only have standard PCI expansion slots and don't have either a PCI-express or AGP slot in your PC then you should just bite the bullet and buy a whole new computer if you're serious in the least bit about playing modern 3D games. It's only going to get worse for you otherwise. Hope this helps.
