Hi again. I create a new subject because I thought the problem was solved, and therefore the old subject was marked as "solved". So, I had this problem (I copy-paste the old post, that you can find here : http://www.tomshardware.co.uk/answers/id-2005955/computer-randomly-reboots-insufficient-psu-overheating.html#xtor=EPR-8809) :

The problem I have seems to be tricky... First, it began with the installation of a new game. I played this game a lot during the first day without any issue, but the day after, my computer started to crash (and by crash, I mean : shuts down and restarts) after a few time in game, and again after a shorter time, and again, to the point where just starting ANY game with 3D animations (even a very old one : I tried with Star Wars : KotOR) instantly crashed the computer.
So I searched the internet. I checked the temperatures of my GPU and CPU and they were normal. But then I noticed that my PSU was insufficient (400W for a 450W estimated consumption). So I bought a new one (a 630W Antec one). The crashes stopped for three weeks, but a few days ago they came back.
I searched again the internet for other possible causes and read that it could be my RAM. Soooo I decided to unplug one slot to test it (I have 2x2 Go + 1x4 Go), and the crashes stopped again. But today, it began again (with the unplugged RAM still laying on my desktop...) ! I don't know what to do next...

Oh, and there's another interesting fact that could give you a clue of what's happening : when I start my computer, after one or two seconds, before anything happens on my screen, it shuts down and restarts, sometimes once, sometimes twice, and then eventually boots.
Click to expand...

An answer suggested me to reinstall my GPU drivers. I did it, with a clean uninstall, and the crashes stopped for a while, but now they are back (they are sneaky bastards). I re-reinstalled my GPU drivers, I even reinstalled Windows, but it keep occuring, and I have no idea. I'm getting very worried (and angry) about this issue... Your help would be very, very, appreciated.

Thanks in advance !

You have the SSD and I don't know when you build the PC. But I know SSD is very picky for the driver, like chipset driver, SSD firmware, MB BIOS, etc, so you maybe need update all the drivers and SSD firmware. Also do you OC the i5 2500K, and how about the RAM since you have 2x2GB + 1X4GB, sometime if they have different timing and speed than you have problem too.

I'll try installing all most recent drivers for my components. Do you think I need to flash the BIOS too ?
For your others question, no, I don't OC my CPU. I have 4Go of Corsair Vengeance DDR3 at 667 MHz, and 2x2Go of GSkill DDR3 at 800 Mhz. Besides, when I tried to unplug one slot, it was the 4 Go one. So the computer was left with only the two similar GSkill ones, and it kept crashing, so I don't think the problem comes from the RAM.

I tried removing both the 4GB and the group of 2x2GB, clearing the CMOS each time. I also tried installing a few drivers. But none of this worked : still crashing. And now I reached a whole new level : the screen won't even turn on when I boot !

I went to a friend's house to test my GPU and CPU on his computer, and they worked just fine, so the problem lies somewhere else. We reached the same conclusion : that it might be the MB, and that I should try to boot with only GPU and CPU. I did it, and it still didn't work... I guess it's the motherboard that is dead. Is there a way to be sure ?

Well, it seems legit, but it would be... displeasant to spend a hundred euros in a new motherboard only to discover that my computer keeps crashing. Anyway, I bought a new MB (GIGABYTE GA-Z77-D3H for your information) online, it should be here the day after tomorrow. I'll post a message by then to tell you if it worked.

Anyway, thanks a lot for your help and support !
