Steam installed... HL2 downloaded and updated, along with HL, CS:S, and the Source SDK.
HL runs fine... Source SDK and HL2 however will not start. The MENU for the SDK starts, but when I try to launch Hammer, NOTHING comes up... same for HL2... launching just doesn't happen.
Here's my system specs
XP Pro
AMD Athlon 1.1GHz
384MB RAM
DirectX 9.0c
VisionTek Radeon 7000
(the card is a 64MB but dxdiag is showing the following)
Approx. Total Memory: n/a
I've restarted my comp 5 times now, and NOTHING still! As I said, HL runs fine, but anything source based won't run
