Solved Random shut downs and hard to boot PC

March 2, 2012 at 06:48:30
Specs: Windows 7 64bit, i7 920 2.7ghz quad, 8gb DDR3
Hey there, my computer will randomly shut down, specifically when I run a game or anti virus.

It also is hard to boot, if i press the on button, it will all turn on for a second then turn off, it wont boot unless I hold the on button for a few seconds then everything boots normally. But I will get the random turn offs.

Ive noticed the CPU load is spiking a little, normally at 0-1% it spikes up to 10+% when im not doing anything. My temperatures are fine, from reading other things I think its the PSU but need help diagnosing. I have also recently installed more RAM but it has booted fine with this RAM installed before.

Thanks so much for your time

will vote best answer if solved

"thermal paste is applied correctly"

Since it doesn't appear you did it yourself, did you actually see it being done? The "vertical line" application method is recommended for the Core i7. If it was done any differently than shown below, it was done incorrectly & may contribute to overheating. As toxic51 stated, 50-60C at idle is not good.

It just boots as usual like it does without safe mode, but i cant run any games to test if it shuts down randomly like before.

did you try safe mode with networking?
What AV are you using that won't run?

Well it doesnt shutdown but like I said I cant run a game to be sure.
I cant run a virus check because it seems to 'overload it' and shut down.

Have you checked the CPU temp? Is your power supply adequate?

Its a 750 psu, which runs two hard drives, my i7 920 processor, 8gb ram, 3 fans etc, do you think this is enough? my cpu temps are around 50-60 which is good for my computer

750 watts is not what we intend to find in a power supply we need to know the amps on the 12V rail
and no the 50-60 degree are not good if they are on idle, this shows me that u have a cpu heatsink issue who installed the cpu in ur computer? whoever did it must have not installed it properly and did not apply thermal compound correctly.

thermal paste is applied correctly, and has been applied by different people with the same problem, its a double threaded quad core, the i7s do run at higher temps than usual

yes the i7s run at a high temperature but they reach max 40 on idle and 60 when u game thats only in places where the weather is hot.
try restoring all bios settings to defaults, and if u can get to safemode run a quick scan using malwarebytes delete what it finds. if it shuts down when u run malwarebytes or any game at that matter then u have either an overheating issue, bad ram, bad graphics card or a bad power supply unit

Hard to boot may or may not be of importance. Some power supplies just don't keep the power up for long enough to get latch from motherboard.

I'd boot to a live cd and run some cpu torture test or at least run memtest.


I'd look at event logs to see what is causing the shutdown first. May be in dump logs too.
