Newly built gaming PC shutting off randomly

dylza747 · May 27, 2014

So about a week ago I built my PC, had some slight headaches but they were all solved and I've been playing arma 3 and stuff for about a week now. Suddenly, last nigr I realised my PC turned off randomly without warning but my power button LED was flashing and my mouse LEDs were still switched on. I then opened up corsair link and saw that my h100i temperature meter was flashing red at 24 degrees.

i5 4670k
MSI gaming 5 mobo
G skill sniper 8gb
Crucial 240gb SSD
Msi r9 280X 3gb
NZXT H440
Rm750 modular psu

Also, when I restart my PC, it gives me no option to get into my BIOS and goes straight to windows. Also for the past two nights I've left it on overnight to re download stuff like bf4 which I can't really do anymore.

hmm
download a program called hw monitor
and tell me what the cpu/nb voltages are
and the cpu temp for each core
and well go from there

allegedsin :

core 1 is at 29 degrees
core 2 at 25 degrees
core 3 at 24 degrees
core 4 at 27 degrees

i5 4670k VID 0.831 V
minimum: 0.720V
Max:1.130V

correct me if ive given you the wrong voltages im kind of new to all of this

sorry for late reply been busy
in any case yes those are the voltages i need to see

and those temps are perfectly fine
well anything under 30 C is considered very good
so what this determines is it is not overheating

and the voltages are fine

and as for the h100i 24 degrees it should be fine
i mean my water cooler temp is 40 C and i have no problems

now only 3 explanations i can think of
1: try to change the screen resolution on the monitor or tv itself and the pc sometimes the del and F2 button don't show because of the resolution it may be there but it would not be visible because it past your viewing point well that's a possibility

2:
Clear your bios
depending on motherboard you either have clear cmos button or a jumper to clear it not very hard to do either way i would read the manual for your motherboard

3: which is what i think it is mostly just follow the steps
first click start
next click on control panel
now click on the view by on the top right side and click large icons or small depending on what you like better
next look for power options and click that
now click the bubble high performance
then next to high performance click the advanced settings option
and make sure the turn off display or put the pc to sleep is on the never option
after that there an option on the bottom left says change advanced power settings click that
now theres a bunch of drop down options
click hard disk then click turn off hard disk after
and make sure it is on never which is 0
after that click the sleep option
and make sure everything is set to never
and the wake up timers are disabled if you have that option
and lastly click display option then turn off display after set that to never

what that does is make sure your pc does not shut off unless you get a windows update and it restarts or you shut it down or your house loses electricity
and should solve your problem

hope this helps
let me know what option works for you

Ok I'll try them tonight, but I've also had my PC staying on overnight when I was downloading dayZ the other night and it didn't switch off. It's just really weird :/
