8gb Corsair Dominator ram (one mudual)
MSI ATI Radeon HD 5850 1GB
Paowe Supply 500wat OCZ

I have recently upgraded from a pentuem duo core to an i7 and the only thing ive upgraded was my cpu, my system runs very cool, barely warm to the touch after gaming for a few hours.
when i had the duo core processor in my system i was able to play sims 4 almost on max graphics/settings it will play smooth and no glitching or erros, since ive put the i7 in, every game i have will glitch on almost any graphic settings, abut some times ill turn my pc on and i can play a game no problem.

I persopnaly think io need to upgrade the power supply, but the shop that sold me the processor said to me that 500 watt will be ok my my system. but when i called them today they said i need a better psu and theres nothing wrong with my cpu

I am just trying to get some one elses advice and oppioning on this.
what do you think I should do?

It could be your PSU. 500w Should be enough, but many budget PSUs overstate their actual suitability.

It could also be that your heatsink/cooler is not properly mounted to the cpu. The fact that everything feels cool could indicate that the cpu is overheating. In order to work, your cooler needs to get hot. It is very common for people replacing CPUs to not properly apply thermal paste. If you have too much paste or any gaps in your paste, heat will not effectively transfer away from your CPU.
