Games stopped working on my PC

[Boothroyd]

i brought 3 games recently for my PC; warhammer mark of chaos, rayman raving rabbids and starship troopers. I recently deleted most of my other games to fit them on. I have the memory on my PC but the system crashes when i play them, is there any reason for this? PS. It isn't my memory because i recently cleared my PC and i have plenty of space left. Also all of the games are supposed to work on my system.

Try a Defragmentation. That might solve the problem. Sometimes it can take a while, so set it going when ur just about to go on a night out or summat. Hope it helps
