I have not been able to find something similar anywhere but here goes:
Windows7, radeon 5750 video card, quad core processor. All drivers up to date. Computer cleaned out, and all fans working perfectly. My problem is two part. First during L4D2 my game will randomly blink to black screen then I'm at the desktop with the game minimized in the taskbar. Something similar happens during BC2, but I dont CTD, I flicker and then I am immobile for 2 seconds or so. I thought this was just related to steam games, but my Origin BC2 has the same flicker issue. I get no error messages, and I have verified more caches than I care to discuss. Plus with 5 uninstall/reinstalls its not the game. Now I am wondering if it could be the video card, but I have a clear screen with no lines or issues of any kind. Being a so-called noob at computers, I have no idea what the problem could be. Any ideas? Thanks for any help I can get. Peace!
