Computer freezing

by Johnno420 / October 6, 2014 2:40 AM PDT

Hi, my computer has a problem where it constantly freezes. At random times it'll either bluescreen or just freeze, and it happen's quite a lot.

I bought and assembled the computer myself about a year ago and the issues has happened on and off. I ignored it because it didn't happen much and kinda went away, but I cant seem to do anything without it freezing lately.

It isn't to do with the heat or cpu/ram as I keep tabs on that stuff, and it happens sometimes when I'm doing nothing.

I've been told it may be a graphics card issue, or possibly the different components clash (because I built it from different brands/ not a home kit). I've reformatted it many times and it still happens, the same way.

I don't wanna go spending money on parts when I don't know the issue. I also have disassembled/reassembled the computer a few times just in case it was a build problem.

If you want me to list the parts of the computer I'd be more than happy to. Any ideas what it might be?

Clarification Request
Have you done the usual work?

That is the usual cover off, canned air and heatsink compound replacement? Omitting the parts is going to hurt the discussion but let's hear if you've done the work. Many folk don't, won't and try to avoid it. Some of the newer techs trot out temperature readings. All over a few minutes to hour work. Maybe it's best to not talk about this and keep the shops busy.

Sorry for not replying earlier I've been busy and havent even looked at the computer. But I have gone through and checked connections, dusted and replaced the heat sinc paste. I'd be happy to take it to a professional, but I've avoided that simply because it seems to be erratic and hard to predict. It'll Halen when I'm playing games one minute and when Im simply watching movies the next. I just don't want them to not experience the issue and think it's solved.

My parts are:
Motherboard asrock z87 extreme 4
cpu Intel i5 4670k
ram ddr3 corsair venegenace 2x8 gb
Graphics raedeon 7850 hd
Psu thermaltake smart 650 w
Cooling cooler master hyper 212x (its just a bigass heat sync)

That's what I have. Again sorry for the late reply, I really do appreciate the help. I'll try another reformat and look a little deeper.

That helps.

In reply to: Pretty much shows a single +12V rail so that removes one of the common concerns.

HOWEVER the "K" series CPU is often a sign the machine is/was overclocked. DON'T DO THAT without expecting trouble. To make matters worse some folk demand support for overclocked PCs. I guess the dishonest tech shops will take the money...

OK. Let's say the heatsink on graphics and CPU was done right. Now it's time to check firmware versions on BIOS and SSD. I check the HDD and ODD firmware too while I'm doing the deep inspections but when I have a new cranky PC I'm updating the BIOS and SSD because that's where I've run into out of date troublesome versions.

After that I'm going over the windows install with a fine tooth comb. Checking that the motherboard driver was installed, then the audio, video, network and then the INTEL RST app.

Windows is troublesome to get installed right today. I had hopes that would be addressed but it's just as it was from the beginning.

In closing, leave the cover off for now.

Hi Bob,

I had a similar problem due to the motherboard not being fastened to the case properly.
You should check to ensure that the motherboard is grounded.

I would remove the graphics card and try the built in graphics and see if that is a problem area.

a few questions

have you run memtest via a bootable cd
have you stress tested the pc with any software
have you access to another psu for testing purposes

finally have you uninstalled any beta drivers or other software, or if its recent, tried a system restore or re-install as a last precaution ( It may work but can be a waste of time if hardware related).

As you suggest remove the graphics card and the drivers.

A couple of issues I have had are

Accidentally shorting a usb on the back plate ( took me hours and lots of select language )
Bad drivers
PSU faulty
Memory faulty

like anything its trying to recreate the failure with as little hardware in as possible.
