Been asking few people and its sounds more the the power supply but i dont know about the heat im using the LEET Monitor and it shows idle 80F gaming 110F(depends on what game). heres my PSU its off brand startech: http://www.startech.com/Computer-Parts/PSUs/ATX-Power-Supplies/Reliable-400-Watt-ATX12V-201-Power-Supply-with-20-and-24-pin-Connectors~ATX2POWER400 . happened on tuesday playing LoL just shutoff and restarted. its very random during games be any game really, if it is that PSU im thinking of the corsair 600w if its the heat need some tips.

i dont know how to and thanks little odd but pc is back on with the corsair 600m
80F (35C) and 110F (45C) shouldn't be a problem. If it was 80C and 110C then yeah.

That power supply is pretty crappy. Get a good one from Tier One - http://www.tomshardware.com/answers/id-1804779/power-supply-unit-tier-list.html#13224310

If your pc stays on long enough, download and run HWinfo and tell us the min and max values you get for the 12v, 5v and 3.3v voltages. If they are more than 0.2v from the target then the psu is faulty.

If its a bios hiccup then it might be worth doing a bios/cmos reset.

HWinfo
 
1. CPU too hot (38C) - lower Vcore by .05V, raise cpu fan speed to just over 1000rpm

2. Power supply voltages all too low. Replace power supply with a good one. Something form Tier one if possible - http://www.tomshardware.com/answers/id-1804779/power-supply-unit-tier-list.html#13224310

For a pc running a GTX750 you need a power supply that will provide a minimum of 20A on the 12V rail and 400W in total eg Antec HCG 520M, XFX 550, Seasonic 520
