Yeah you are right. I worry too much.
And your right about me not being a do'er. This runs in my family too.
Casing is the iball i6363 and the PSU is just nothing but a iball 400 W.
Or maybe its just the fact that I live in India. People here aren't that techy, and sometimes, not at all techy. When I asked for the GTS 450 in the hardware shop, the vendor told me that they had a better card, the NVIDIA Geforce EN 9500 GT from MSI !!
Clearly! Most of the kids here, look at the VRAM on the video card when they buy one ( especially the 1 GB versions of a card )
Well we all know that the GTX 460 768 MB can beat the 9500 GT 1 GB just by blowing. However, over here, many people think the other way around.
Well, back to topic, I re-installed the drivers and problem solved.
