Random game crashing/freezing after gpu upgrade?

[borko3fkovix]

So I've upgraded my graphics card from Sapphire HD5770 to Msi HD5850 Twin Frozr 2(about 2x better specs in gpuz) because it wasn't stable, was overheating to 97C, would turn on pc after 2-3 restarts, and so on.
And this one is great, my computer is much faster now, it doesn't overheat(28C idle, 55max), BUT...
I wanted to play Crysis 3 and i played it for like 3 mins or such, and i get "dxgi_error_device_removed". So i update my driver and i re-enter the game and i play it for 10mins now and everything freezes, and i have to restart my computer. And it also happened with the goat simulator. But it never happened in battlefield 3 which is also hardware demanding.
So what is happening? Also, when i go to open gpuz it says something about openCL error but i cant seem to find an update for that.
And just to mention, i played Crysis 3 and finished it on 5770, so we can say that its not because my current one is too weak.
My specs are:
CPU: Intel E5300 Dual core 2.6GHz- yes i know its bottlenecking the sh*t out of my gpu, but that cant be the cause of the freezing, can it?
RAM: ddr2 2gb,
PSU: blueberry 500W but its max power is 550W(wtf), its not very popular or its just in europe but it is branded(i think) http://www.itsvet.com/proizvod/blueberry-psb500-500w/comp_comp_powersupply/256/428
MOBO: Dont know if its relevant but its GA-P31-ES3G (ALSO, it has PCI-E 1.1 and the gpu is 2.0 i think, so another suspect there)
HDD: Now this is my primary suspect: Its some hitachi hdd from 2006 i think, it is 160GB cap and has 140 bad sectors (18% health in Sentinel), but as i said i never had any problem in games with my old card.
I know my pc is outdated, im working on updating everyting, but i need to know did i made a mistake with this gpu?(i've bought used one so no warranty)
Sorry for the long post!

The problems could be your RAM, HDD, or used GPU. Don't worry about your CPU (even if it bottlenecks).

First, try installing different AMD drivers, from the newer to the older ones. If problems continue, go back to your previous GPU (yes, a fucking shitty solution, knowing you just bought this 5870..).

Second, try adding more and new RAM. 2Gb DDR2 RAM won't help running Crysis 3.

Third, check for bad sectors on your HDD using chkdsk.

And finally, if I were you, I would upgrade that PSU. I've seen somewhere it's an unknown China manufacturer, with bad reviews. It's not even between the Tom's Hardware PSU brands list. It also may affect the rest of your hardware on the PC, and might cause lots of problems later.

If you just plan to build a new PC or buy some new hardware, send me a message or ask here on the forums, I'd be glad to help.
