Win7 Hard Freezing randomly, no BSOD

***EDIT: Jump to post 13 for an updated continuation***

I'm in a tough situation since my fathers computer which I built about 5.5 years ago is having issues but he lives 6 hours away so I cant easily troubleshoot it and he is only capable of so much. I'm ideally trying to narrow down the potential issues and help decide if I should just work on a complete rebuild (and know what can be reused) or give him additional simple things to try and fix it for now.

Going from memory, the computer consists of:
MoBo: MSI K9N2 SLI Platinum
CPU: AMD Athlon 64x2 3000+
Cooler: ASUS Silent Knight II
GPU: NVidia GTX (750 or 750 Ti?) - Put in 1 year ago
Ram: 4Gb Kingston HyperX (DRR2?) -2x2Gb
PSU: Rocketfish (700W?) - Original failed, got for free from a friend
HDD: 1TB 7200RPM (Samsung?) - Used to be the secondary drive for storage until my Velociraptor 10K
RPM died so that's when I put Win7 on the 1TB and only have that drive used.

It originally had 32bit XP, but about 4 months ago I put Win7 Pro 32Bit on since XP is no longer supported.
So it has a rather new clean install with minimal programs.

Basically all of a sudden the computer went from working fine to freezing randomly anywhere from 2 to 15 minutes after starting. Its always been a hard freeze with no BSOD or error messages, cant have the Num-Lock light change or anything. It is not limited to any certain programs running before it freezes.

-I was able to get him to run an Avast scan in safe mode and it found nothing.
-We tried the Win7 Memory Diagnostic and it sounds like it made 2 successful passes with no errors, but when it went to reboot and show the final results again, the computer froze at the windows logo (the only time i believe it has frozen without logging in) and we never tried it again to see if it matters.
-He opened one side of the case and blew out any basic dust inside and the fans, but didn't reseat any components or get a full cleaning.
-It doesn't seem to matter if in safe mode or normal, it still freezes randomly. (Nothing open, checking email, surfing the web, etc)
-All drivers should be up to date or within a few months other than the BIOS is probably near original.
-Win7 updates should have all been installed up to date.
-We were able to get a system restore to go through from about 2 weeks prior to be sure it was a time things worked fine. (It took 2-3 attempts before it sucessfully did the restore.)

I'm looking for help in narrowing down potential ways to fix it, as well as confidence that certain components wouldn't be an issue currently in case i want to reuse them.

1) Should we rerun the Win7 Memory Diagnostic until it goes perfectly and shows the final results?
2) Is there any chance components weren't able to use Win7 and failed in that short time? (I assumed if they weren't compatible it just wouldn't have worked on Win7 from day 1)
3) Should i try and run Malwarebytes (MBAM) in safe mode? (Again its a pretty fresh install and minimally used so I dont see that being a problem.)
4) Is there any chance the Hard Drive is bad or needs a disk check? (That's a component I'd like to know is safe to reuse if I do a rebuild.)
5) Is there any way to see if its a heat issue? I'm not sure if the board has any temperature sensors. Should we run things while the case open for more air flow?
6) Anything point to the GPU being an issue? (Another component I'd like to reuse if doing a fresh build)
7) Is the memory diagnostic enough to clear the RAM as being ok or could it still be an issue and needs to be tried with 1 stick at a time or different sockets etc?
8) Any drivers to force check for updates or could the BIOS and Win7 not have worked well together?
9) Could it be an inconsistent power issue or anything with the PSU? (Another component I'd reuse if its for sure safe.)
10) What else to check/try/scan/etc or what additional info do you need?

Thanks in advance.

Sounds like a heat problem to me. Install Speedfan and monitor the temps, see if they got high when the freeze occurs.

Have your dad shutdown the computer and remove the power plug. Open the case and clean it out with a soft brush and a can of compressed air. Check the vents in the power supply, inside and out and all fans to make sure they turn freely and are not clogged with dirt and dust.

With the side of the case off, plug in the power cord and power up the computer and see if the fans are turning: power supply, CPU, case, video card.

If temps are high, may have to remove the CPU heatsink and clean then reapply a good thermal paste, ditto if there is a plug in video card (PCI/PCI-E/AGP).

I will have him try the temperature monitoring tonight, im pretty sure he did a thorough blow out of all fans but will revisit that as well. It sounds like he did try to run the system with the side door open to allow a little more airflow and didnt really get a different result. So in my opinion the only possible heat related issue would be like you mentioned with the heatsink. Is it common for the thermal paste to dry up or go bad over time if nothing was ever changed or the parts seperated?

Is anyone able to comment briefly on a few of my initial questions regarding if things like the HDD, GPU, etc are most likely not an issue and safe to both rule out as well as reuse if I go with a new build?

Other than heat, what are the next most likely issues? I still have a feeling its memory related and curious if the memory diagnostic would include a way to test if the socket itself went bad or could cause this? I think i recall having an issue a long time ago where i ended up putting the 2 RAM sticks in the secondary slot configuration (3&4 instead of 1&2) because it seemed to have lock ups or something and troubleshooting lead me to the ram sockets back then. Maybe the board now has 3 or all 4 sockets failing?

You questions of what can it be. Well it can be any or some of the things you mentioned.
Windows 7 built in memory test is not very good in my opinion.
Because you have stated that you had memory problems before
I suggest using this tutorial using MemTest86+.

RAM - Test with Memtest86+


Normally when memory goes bad it will give a BSOD but no always.

Watching temps closely as Ztruker has posted is very important. You must be sure their is no over heating problem. Over heating will kill a computer.
Yes the compound on the cpu can break down over time. 5 years is a long time for compound. I never let mine go over a year but I'm paranoid.

A Rocketfish (700W?) power supply was questionable when it was new.

It's very difficult troubleshooting a computer problem over the internet and very difficult when their is a 3 way troubleshoot project.
We shall try.

Most of the things you are in question of when going bad will cause a BSOD in most cases except the power supply.

If you are having BSOD problems we do have some very good people that work with BSOD problems.

Thanks for the reply, I do know that so far there has never been a BSOD issue, not sure if that makes it easier or harder to troubleshoot, but at least its limited to one problem of a full system freeze.

If it is a heat related shut down would that be logged in the event viewer or whatever its called?
Or perhaps its worth checking regardless of the issue.

I agree on the PSU, i'd never buy one of those myself, but it was free and worked perfect from day one a few years ago so I never cared to replace it for him. If you are suggesting there is a chance it could be the PSU that is causing the issue, I will consider a replacement if I go with the rebuild option.

I will look into memtest86, i've heard of it plenty of times, but never used it myself so I will have to read up enough to be able to explain it to my father over the phone if we get to running it.

As far the original Speedfan suggestion, that will have to wait until tomorrow and I will report back on it then.

Lastly in regards to thermal paste degradation over time is that something you suggest I replace on my personal PC if I haven't changed it since built almost 2 years ago? (I7-3770k with an H100 on a Sabertooth Z77 MoBo if it matters)

I really don't know if their is any place you can find the longevity of any thermal past.
I just change it to make sure and it's easy to do and it's cheap.

Here is a good site to take a look at.

Haven't been able to update yet as it looks like he is having a hard time with it booting at all lately, possibly messed up the OS since I think it froze during one of those "don't turn off your PC" shutdowns while installing a few updates.

I'm going to see if he can try 1 stick of RAM at a time and possibly it on long enough to test the CPU temperature.

Or perhaps the PSU is indeed failing.

I've started to look into fresh build options and am trying to decide what I want to run. Possibly do a complete AM1 build or find a low budget i3 or similar build to keep it on an ATX size board to use in that case, but that was mostly relying on the fact I wouldn't need a PSU so it'd be good to see if its working alright.

Let us know what you decide to do.
Because you are not at the computer it would be very difficult to explain through a 3 way how to use the Windows 7 DVD and do repairs.
Are you with the computer at this time or are you still 6 hours away?

Yes I am still 6 hours away, we planned to meet up in late august anyway so I'm thinking I'll just try a few more things to see if we can get that one going for short spurts every now and then to check email, but then ill have a rebuild planned for when we meet up. I've done windows repair a few times with XP just never Win7 so if a repair is needed then Im sure I can figure it out from an online guide so I can see the screen shots and explain to him. Hopefully he can get it started for a few minutes to at least know it isn't an OS issue and still somewhere in the hardware. Then ill just decide what all I want to attempt to reuse vs. just buying new to be sure. A good example would be the PSU, for $40 on sale I can probably find a good enough one that is plenty of power for a basic build.

Alright it looks like he was able to get the PC to run for about 15 minutes this time which is one of the longer runs since the issue. He did take out one stick of RAM which may or may not have made a difference as he didnt try multiple setups with them.

He was also able to get speedfan installed and running and I am unsure which sensor is for what, but obviously 2 of them are pretty high, maybe one or both are general case temp? Is core the cpu, because that seems pretty low. Basically just seeing if we can rule out the CPU as overheating or not.
