Thanks for the advice people, i did think it was graphics card upgrade needed but wasn't sure if what would be suitable,
The GT 710 only came about after useless advice from local pc repair shop, was only £40 so meh.
The Ram is 2 x 8gb sticks
I had a look to see if cooling was an issue, when in bios, the CPU has 80ºc-83ºc temp, is that normal?
Should i look for a suitable cooling with the bigger graphics card. Thanks guys
