I have a real issue and I would greatly appreciate your help. I just recently built my PC with the following configuration: i7-3770K @ stock 3.5 Ghz 16GB Corsair RAM (PC-12800) nonoverclocked ASUS P8Z77-V Deluxe motherboard 1TB Hitachi HDD @ 7200 rpm 2TB Hitach HDD @ 7200 rpm 120GB Kingston SSD for Windows 8 boot only 250GB Seagate HDD @ 5400 rpm (this was only installed to remove files) 12x LG Blu-Ray Drive 24x ASUS DVD-RW As you can see there are no graphics cards so I am using the integrated Intel 4000 graphics that is part of the i7-3770k. My problem is that when I try to run games my PC suddenly freezes. I first tried it with Torchlight 2 which has a known issue of freezing PCs so I tried to run Half-Life 2 and Doom 3 (yes, these are old games). All of them froze my system. I know this can't be because the games are old: I have a Dell Inspiron laptop that can play all three games without any issues so I am assuming there is something going on with the CPU. Can any of you provide any technical assistance as to what might be going on? I did try to install some old X1900s (yes! Everything's old as I haven't built a PC since 2005) but I did not want to hassle with those just yet. Any help would be grealy appreciated.
