I just installed Half Life for old times sake, and give it a whoorl on my new pc. For some stupid reason it wont play the dang game... Why the heck not? Id used to run fine on my POS gateway 400mhz 100pc ram!
Do you have more than one CD, like a CD and a cd/rw or dvd? Some older games have that problem if you have more than one CD drive and usually there is a patch by the company to fix it.
