Dec 2012 I purchased Gigabyte 650 Ti OC 1GB and replaced it with my Palit GTS450. The problem that I have faced since then goes like this - when I am in middle of a game (tested Mass Effect 3, Spec Ops The Line, Battlefield 3 and some other games) I believe the graphic card runs into an issue as the sound output freezes and the screen blacks out and gives me the 'No Signal' message. But the computer is still on and everything else works fine, only videocard cooler stopped working. I am even able to Shut Down the PC via the start menu manually (blindfold). When I boot the computer I get a video adapter error via bios beeps, it boots, but without any images on the monitor. Only after next attempt of boot the PC starts running normally.
I tried different versions of videodrivers, same problem with every version. I've had no such problems with my previous graphic cards since 2 years.
Configuration:
MB Gigabyte MA790X-UD3P, BIOS type Award Modular BIOS v6.00PG. I’ve updated my MB bios from F4 version to F7b, no result.
RAM - OCZ XTC Platinum OCZ2P10662G DDR2 2GBx2@800MHz. Checked it with Memtest x86, no errors.
CPU - AMD Athlon FX-5000 @ 2,2GHz, Deneb. CPU Cooler Titan TTC-NK35TZ/PW. Originally I unlocked 2 more CPU cores using Advanced Clock Calibration, after this problem begin I disabled them, no result.
Case – InWin C720, PSU - FSP ATX450PNF. PSU capacitors are fine. Changed my PSU with FSP ATX550PNR temporarily, no result.
HDD – SAMSUNG HD103SI (1000 GB, 5400 RPM, SATA-II) and ST3250310AS (250 GB, 7200 RPM, SATA-II). Checked them with Victoria, no serious errors.
OS - Win7 x64 SP1. Also I have Windows XP SP3 on my another HDD. Same trouble on it, with different videodrivers.
