I built PC last week and was playing game last night PC was on for about 4 hours then it died and would not start again slight smell of burning in case. Tried this morning and it turned on and running fine.

Now I am Thinking this might be my fault for buying a cheap 750 watt Power supply £20.00?

Many Thanks

Anything else could be cause?

PC spec
Gigabyte 970A-DS3 mother
AMD FX 8120 3.1GHz 8 core
ATI Radeon HD 5770 1GB
Corsair 16GB Ram
Windows 7 64 bit

one more thing how do add pc specs to post and replys
 
Yeah that's the very PSU I have powering my main rig. Works nicely for me with a single HD 5870. :)
 
Check your temps too. Your pc shuts down when the temps reach there maximum (can also explain the smell)
If your temps are the problem, reapply the cooling paste.
But even if your temps would be the problem, buy a quality psu!
 
I didnt apply any paste the cpu came with fan with paste on it the pc died again tonight it seems only when i start gaming it for a bit it dies

He said it fired up and ran fine, so I doubt anything fry'ed. But like what was already stated, get a better PSU regardless. We can't preach this enough, PSU's are the heart of any rig, there for, needs to be top-notch or close to it.

Not saying this is the case, but it could of been a roach/bug(which loves heat) crossed over a circuit and short-circuited out for a sec. seen it happen befor.

Temps don't get that hot for there to be a smell. CPU temp monitoring feature shut down the PC around 80c which is not high enough to produce any smell.

My stock intel fan really melt around the iron/copper plate lol.
(That was my pentium D without thermal paste :P)
 
When it dies it does not shut down it dies like a power cut then when it cools down it starts again I think the new PSU should be here tomorrow i will fit it and test again.
I have a core temp display and when surfing it stays around 20 to 40 degrees when gaming i can feel the heat rising from the fan in the back
