Try removing the card and see if you can reboot it.
Look on Coolermaster's website or MSI for power supply calculators, you input your pc specs, it gives a rating for psu power. Many say this is false, check it out.
I tried reseating the card but nothing happened unfortunately. No signal appears on my monitor. Could this be the card or the psu may also be the reason? I've also tried the onboard display and it booted normally.
Just to see if you have enough power, if not it could cause damage to the gpu and motherboard.
Those calculators will do the exact opposite, they are horrible.
I was able to try the card in my friend's pc and it didn't worked. LOL. Got it RMA'd and now it works perfect. Anyhow, I also want to replace my PSU just to be safe. Any thoughts about 450w fsp hexa and corsair vs?
