Computer slow and freezing up after upgrading Graphics card and RAM

Motherboard: Gigabyte GA-890GPA-UD3H Graphics Card: Nvidia Geforce GTX 770 4GB Processor: AMD Phenom II X6 1090T 3200Mhz RAM: 12GB Novatech DDR3 PC3-10600 1333MHZ- made up of 2x4GB and 2x2GB of RAM PSU: Corsair Builder Series Modular CX750M - 750 Watt 80 PLUS® Bronze Power Supply

Hi sorry if this should have been put in another thread. Basically my computer is very slow and freezing up especially if I attempt to run multiple or more demanding programs. Games that loaded prior to the upgrade now freeze and stop responding on the loading screen, if a game does load it tends to lag. Sometimes, usually when loading a game, the monitor will loose signal, however the PC tower will still appear to be on. When this happens the only thing that brings the display back is to restart the PC. When just browsing the internet the computer runs fine.

I have double checked all the internal cabling, everything seems to be in place. I have ran Furmark and checked the temperature of the CPU when running games. GPU temps- 38 Celsius idle - 85 Celsius after running Furmark for 20 mins CPU temps- 35 Celsius idle- 50 degrees when running game. Initially I thought the power supply unit, but the Corsair model I listed is newly purchased and the problem still persists. Un-installed Display drivers from Device manager and re-installed Nvidia Drivers. Tried different combinations of RAM, and going back to just the 4GB of RAM I had before the upgrade. Anyone have any ideas what else I could try? Thanks

  1. reseat grahics card

  2. try with just the new RAM 8G

  3. check all BIOS settings for RAM and CPU speeds are correct.

Hi I have already tried 1 and 2, but about the BIOS what is the RAM and CPU speeds listed under?

You do not say if you have a 32 bit or 64 bit operating system

  zpower2011 15:37 24 Dec 2014

The operating system is Windows 7 64 bit

OK. Thanks. It helps

I found DRAM configuration, but it only states the frequency of 1333MHZ not the speed. The only thing I could find under CPU was CPU clock ratio that states 32000MHZ and CPU northbridge frequency 2000MHz, but again no speed. I am a bit concerned about the CPU temperature however as on bios it started at 58 Celsius and went up to 62 Celsius. However when I tried CoreTemp again it said 35 Celsius?

Yeah its the stock AMD cooler, AVC Z7UH40Q001 which I have not changed from when I bought the original build in 2010 so I don't know about the heat sink compound

Yeah your right the heat sink probably needs upgrading as I have tried running Core Temp, Speed Fan and Hardware Monitor Pro while playing a game, and all of them detect the temperature for the CPU at 65 Celsius. So I can see why its lagging and freezing while trying to load up a game. However the resting temperatures seem fine, all three software detect the CPU at around 35 Celsius and GPU at 25 Celsius, so I don't understand why the PC is so slow to load on start up and will freeze when looking through hardware setting, when the temperatures are still reading as low. Can the third party software for reading temperatures be wrong?
