i've got no clue what is wrong with it...i was playing hearthstone and all of a sudden the display filckered and went black (all sounds present), waited a minute or two and the display didn't come back. restarted the pc and all i get now is a NO SIGNAL error. all the fans are working and nothing is remotely hot or even warm on touch, the only thing which i've noticed is that the keyboard, mouse and ethernet cable are showing no signs of life (no lights on them).

HIS IceQ 7950 3GB DDR5
768GB HDD
550W PSU
 
it doesn't have an integrated gpu.

although i went on the attic and took another PSU from my old PC and it works now, so it was a falty PSU.

now i'm actually worried if a 400/450 W PSU will be able to perform on the aforementioned pc...
 
it's only temporary a week or so until a new one is shipped. i use the PC casually for watching streams and occasionally hearthstone and league. i'm just hoping if it'll suffice until then cause i don't want to fry anything else.
