Unique problem with my PC

[Brendan]

Hi guys, hope someone may be able to identify the problem.

 

System specs

 

i7 3820 with noctua NH-D14 (something like that)

Asrock extreme 9 x79 mobo

Patriot 4x8gb RAM

GTX 680

Running windows 7 off Samsung 840

3tb Seagate barracuda hard drive

 

 

I reckon this is a really tricky situation but i'll try to interpret it as clear as possible.

 

My PC has been having issues for quite a while now, half a year at least, where sometimes after sleeping in Windows 7 it won't post. I managed to find a fix soon after where i would hold down the reset CMOS button for 20-30 seconds and it would either resume the unsleep, or have a corrupted sleep file and go to a normal bootup. I've searched everywhere i can all over the web and i can't find anything vaguely related to this issue, so i just kept using the fix.

 

IIRC, it started soon after i redid my partitions where i deleted 2 seperate ones and added the remaining space to a single one. (Same drive)

 

I've made my way with this ghetto method for a while now until today. We've recently had a couple power issues where something in the house shorted (100% not my PC) causing it to lose power. It happened once yesterday and once more the day before. Today it didn't happen but instead while i was watching a twitch stream, the entire system just shut off. 

 

First things first is i try to turn it back on but it fails, even trying the CMOS thing and it won't post.

 

I turn off the power and turn it back on. Still no good.

 

What i can see,

 

When the ethernet cable is plugged in, the orange flickering light is ON. When i hold down CMOS it turns off until i let go.

 

I've tried what i know here, where the PC is in the exact same physical state as it was when it was still working 5 minutes ago.

 

After about 30minutes of testing reset and power off/on decided to remove some components.

 

Now, i've taken every single component out, unplugged SSD and HD and left only the power supply connections, CPU + fan and ram installed, yet it still doesn't power on but the orange light for the ethernet port is STILL ON.

 

I'm assuming that my PSU isn't dead because there's power going to my mobo. Once again I'm assuming my mobo isn't dead because it's showing power. I'm also assuming my RAM is fine as i haven't touched it since i built the computer 2 years ago and same with the CPU. I often checked my system temperatures and the CPU was always cool, however the Southbridge was at around 50C because i turned the fan down.

 

 

And here i am wondering what's going on as it was working one second and completely dead the next.

 

Any help is greatly appreciated, 

 

Thanks.

If its a problem with Windows, have you tried a fresh install?

If its a problem with Windows, have you tried a fresh install?

Currently the HD and SSD is disconnected and the problem persists.

I also have the issue where my computer doesn't wake from sleep mode, I have no idea what causes it but when my computer didn't post once i took out the ram and put it back in and it booted straight up. See if that fixes it

It REALLY looks like a ram issue. Try booting with one stick at a time, try different slots for each stick.

[Brendan]

Tried different slot for every stick, different stick per slot and no stick at all and it still doesn't turn on.

This is a good idea. I was having awful problems with Windows 7, crashes on sleep, crashes when opening programs and random blue screens. I reseated my RAM and reset my CMOS and the problems were completely resolved.

I suggest your try reseating your RAM first and if that fails to help then use MemTest86 to test for faulty RAM:

Best of luck.

Do as fizzyfantom said if that problem still persists try installing your windows again.

But boot your windows installation from a USB drive.

Sometimes if you try to boot it from a CD it doesn't load at all.

 

Good luck!

Current problem at the moment is that my PC isn't even starting up. It's not even turning on, no fans nothing.

Take it to the local repair center most likely the problem with the hardware.
