I'd download an run HWInfo.
Check the voltages in MB section.
Must be within 5% of +12, +5 and + 3.3V always,

I'll try to check that.. but I'm afraid to turn on my pc because if the psu is faulty it might toast my motherboard if i turned it on

Honestly, if you're worried enough about the PSU that you're uneasy about turning it on, I'd just go ahead and replace the PSU since it's not a particularly good one anyway.

Ok bro I'll try replacing the PSU ... How much watts do you suggest atleast for a fair gaming pc and.. plus should i get a gold once?

In most cases, wattage isn't the issue, QUALITY is. Problem is there aren't many decent quality PSUs under 500W and with the component shortages from the last year, most decent PSUs have become shockingly expensive relative to what they used to cost two years ago.
