Hello, I have several issues in my 1-month old customized computer. I had OCZ's for my RAMS and had bad modules so I had to RMA it. Got corsair instead which is better but I still get black screen on games, sound goes out and have to reset the rig manually. I don't know if i'm just unlucky for getting 2 bad RAM kits in a row or there's some other problem with my system. I am certain that it's not over heating because my computer is open at the side and I monitor temperature whenever I'm using a hardware intensive software. The GPU is sort of hot though, but it's fan doesn't stop working even if it freezes. I don't know if there's something that's not compatible in my system or there is just a defective part on it. I checked voltages over at my BIOS and things are in good shape there. Any advice would help because I've been pissed off and I thought it would be working real fine because had to spend a grand for this. SMH.... I will post my peripherals below. Thanks a lot!
As far as I know this could be one of the following:
-Insufficient PSU, since Thermaltake's are not known for being "that" good yours may be faulty. You can get a multimeter and check the voltages manually, since software readings are not always accurate, or you can get a Corsair PSU of equivalent voltage and try playing something.
-Incorrect RAM timings and voltages. Some motherboards use a default setting that not always work, check with CPU-ID your RAM's proper voltages and timings, and adjust them in bios.
-Faulty GPU. If the freezings only happen during gaming sessions then your GPU could be failing, try gaming without the video card and using only the onboard IGP.
-Bad drivers. Sometimes conflicting or corrupted drivers can cause all sort of crap, un-install your current drivers, reboot into safe mode, run Driver Sweeper and re-install.
Finally open your Event Viewer after a crash/freeze and correlate any reported problems with the time of it, also, disable automatic reboot in case you get a Blue Screen of Death and take note of the ID and/or use WhoCrashed to analyse the mini-dumps.
First things I would do is manually force the RAM settings in bios and get the latest graphics cards drivers from ATI. ATI Drivers before version 10.3 were known to have freezing problems with 5750s. ATI is on 10.7 or 10.8 now.
