Red LED, automatic shutdown, not booting

[CocoBanana]

Hello,
I might be posting in the wrong thread, since I don't really know WHAT exactly is wrong with my computer.
My specs are:
Corsair CX750 PSU
AMD FX 8350 eight-core processor at 4.0GHz
16GB RAM
AMD Radeon R9 200series (4GB) Videocard
THe problem is, after booting up the pc, sometimes the red LED blinks furiously (on startup, or while staring at my desktop). The computer shuts off and won't turn on again. After waiting for a good while it still won't turn on, unless I cut off the power and turn it on back again. Sometimes the PC runs for a long time with no problems, sometimes it shuts off quicker. While all of this is happening, usually I don't have any suspicious noises coming out of it. But sometimes the fans make an annoying noise either while booting, or while the computer has been running for some time.
I've read up on some forums that I could have a faulty PSU or a cooling problem. I tried cleaning off all the dust from inside (there was barely any). Figured it could be something with my OS perhaps, so I formatted my PC. After the format it ran quite well, so I was happy. I couldn't really tell what happened, but I left it running and came back to a dead PC. Before the format I also had ocassional blue screens, can't really tell the errors right now, but they were due to my videocard usually. But it seems to be fine.
All my fans work too, and no wiring is in the way, no loose bolts or any lying around in the case.
My machine is located in a cool area, so I'm not sure if temperature is an issue.
Mostly the red LED is bothering me (can't really specify my case), which is located near my RESET button. I have a blue LED near my POWER button and after the reset button the red pest is located, which ocassionaly blinks at the moment. Sometimes theres two short pulses. Why that bothers me? Because it didn't happen before this way, until this problem came up.
Any help would be appreciated,
Thanks in regards

You didn't give me any probable cause but I would first look at HD or possible virus ,corrupted boot .Need more Info on problem some scream shot would be useful.

Not sure about any viruses since I just formated my PC.
If it were the HD, wouldn't I be not able to boot it at all?
It boots, but after a while. Sometimes it shuts down and won't boot for a good half hour or so

Can you check in event viewer what is causing the shot down ,first we need to find what is causing those shot downs could be falls mem ,overheating cpu who knows what .

Here's a few, there's 4 in a row :
"The driver detected a controller error on \Device\Harddisk2\DR2."
That error pops an hour before the unexpected shutdown
Also a warning around 3 minutes before the shutdown:
".NET Runtime Optimization Service (2.0.50727.5485) - Version or flavor did not match with repository: Microsoft.Security.ApplicationId.PolicyManagement.Cmdlets"

Like I said could be anything do you maybe have a spare hd to try with other hd .
in event viewer should be critical error and some explanation with that .
Ok let start from beginning
1 its a new install so it cant be virus
2 HD ?

Cant't really specify the model of my HD, but it's 2 TB
I made 2 patritions, one is 100GB 2nd is the rest of the memory.
Windows is installed on the 100GB one, the 2nd patrition is used to save important things like photos and game data (if I have to format windows)
I have a few spare HD's but they're from really old computers.
An hour before my computer shut down I had this error pop up 4 times in a row
"The driver detected a controller error on \Device\Harddisk2\DR2."

look I get this kind of message the moment the comp shot down ,here in your text I only see controller error on hd try updating the drivers for hd or try with new install on other hd to check if that solve the prob .if not then we will be shore it s not a hd and check the error that was created at exact time when comp crashed and upload here.

 

[freeko]

Hey buddy going to sleep you try to do that wit hd if you wish, so we could be shore for shore.

 

[freeko]

Open Action Center and run the troubleshooting tool to test disks and controllers for conflicts. The driver may stall during suspend mode as you said.

Are/have you plugged any USB devices in, apart from Kboard/mouse.
