Hello everyone, I'm experiencing an issue with my month old gaming desktop. Randomly, during certain games, I experience blue screens that occur at various times. Sometimes I can play a game for ten minutes, sometimes I can't even get into the main menu, sometimes I can play for hours, etc. A little about my computer, first. I'm running Windows 7 on an MSI Z77A-GD55 motherboard, with an EVGA NVIDIA GeForce 660 Ti GPU, an Intel i7-3770 CPU, 17GB of RAM, and a Rosewill XTREME Series 750W PSU, along with a Western Digital WD Black 1TB HDD and a LITE-ON Black Internal 12x Blu-Ray combo drive. This didn't start happening until a little over a week ago. I was launching Empires: Total War when my computer unexpectedly went to the blue screen and restarted, I attempted to play again and got about twenty minutes into the game before it happened again. I then went and tried a few other games, Borderlands 2, Darksiders II, EVE Online, Torchlight II, Saints Row the Third, and so on. Each game eventually leads to a blue screen (in fact, all my games do, except for League of Legends) and I've tested my RAM with each individual stick, I've done a system restore and even wiped my hard drive to no avail. I thought then that it might be a heating issue and grabbed an extra case fan and cleared up some of the wiring inside the case for better air flow, but that doesn't seem to have helped much, if at all. Now I'm wondering if it's my video card being faulty. I hope it's as simple as that, the card is still under warranty and I can send in for a replacement if that's the case. Anything you guys have to offer will be great. Here's the problem details that pop up after the crash: Problem signature: Problem Event Name:BlueScreen OS Version:6.1.7601.2.1.0.768.3 Locale ID:1033 Additional information about the problem: BCCode:f4 BCP1:0000000000000003 BCP2:FFFFFA800F622B30 BCP3:FFFFFA800F622E10 BCP4:FFFFF80002FD5460 OS Version:6_1_7601 Service Pack:1_0 Product:768_1 I know that the guidelines say to post a minidump file with this, but whenever I attempt to upload one I get an error saying "The upload file does not have an allowed extension." Any idea what I can do to get it up here? Also, thanks in advance for any help you guys have to offer. ETA: It also says that I need to contact the administrator and file owner to access it, even though I'm the admin of the computer and the only one who uses it.
