Frequent BSOD/PC freezing, error 4105, suspect ATI Radeon HD 5670

You are correct you won't be able to use a Temp program while you are using MemTest.
Once you are in Windows 7 you can use RealTemp to monitor your temps.
The 930 cpu like all 900 series Intel cpu do run a little hot normally. Your cpu has a on die memory controller so when testing the ram cpu temps will clime.

I have a i7-960 with a Corsair H80 push/pull and my temps are about 10C cooler than yours and I'm over clocked.
What I do is check the bios temps compared to RealTemp and see how close they are. That give some idea if RealTemp is reading your temps correctly.

Then I put RealTemp on the Taskbar and watch the temps while I do test or normal use.
With a stock cooler I personally don't recommend running things like Prime95 to load test your cpu. Temps will go sky high very fast.

Just monitor your temps while you are work your system hard. That will give you a real world temp readings.

Thanks, I'll do that.

Personally I think you would go better with an aftermarket air or liquid cooler for an i7 especially if you are going to work it hard and use these for the compounding
Arctic Silver, Inc. - Thermal Compounds < the Arctic Silver 5 but before applying that use this kit Arctic Silver Incorporated - ArctiClean < it cleans thorough and also prepares the surfaces for the compound.

Now everyone has a different method to apply compound/s - myself after using the cleaning kit get a vinyl glove and smear the compound thinly right to the edge of the CPU and cooler surfaces and then place a small rice grain sized spot of compound to the centre of the CPU and then place and fix the cooler down. The compound will "creep" out to the edges when the CPU starts to heat up:)

Thanks for the suggestions. I just killed a couple of hours looking at videos - doing just that (applying the compound and replacing the cooler).

My question is; when installing the cooler, does it have to be flush to the CPU? My stock heatsink uses 4 screws (vice the push pins in newer models) and I think I have a couple of mm gap. I was worried that I would damage the CPU (or snap the plastic screw brackets) if I overtightened it.

The test ran good upto that time. But it got too much high temp there.

Two information will be needed there. What is the wattage of your installed PSU? And which CPU cooler is applied there?

Let us know.

You may need to open the computer to know these things.

Hi,

I opened my PC to get the info you requested. I removed and air sprayed clean the CPU fan and heatsink which were dusty. In hindsight, now I need to get some thermal paste to properly seal the CPU and heat sink. I think that will cool down my system a lot. I also had to remove the PSU to read the manufacturer's label. Note: I am not a PC tech - I have 30+ years experience in the IT field - more in operations and security.

1. My PSU is a Dell D525AF-01 @ 525 W

2. The Dell Studio XPS 9100 has a heatsink/fan assembly - part no. P281K?


The good news is that my PC hasn't crashed all day! And it has been running pretty much 36 hrs.

Just an update to say that my PC has been running great since my last post. Thanks to Arc for guiding me to open the box and locate the source of my overheating problem. The overheating (which was causing my frequent shutdowns and BSODs) was due to my heatsink and fan being very dusty. I regularly opened and cleaned inside the box - but it was the first time I took apart the heatsink and fan (which badly needed cleaning). Thanks also to ICT2LOL and LayBack Bear for their comments about replacing the thermal paste on the HS and monitoring temperatures.

After I cleaned off and replaced the thermal paste on the CPU, my i7 core temps were resting at 36 deg C.

Glad it is fixed mate and maybe it is an idea to do a regular check on those components as it is so easy to do and avoids those problems cropping up again. Now if like me you live a in a very dusty area or have a lot of say pets around - perhaps a check every three months would be the go.

I usually check every six months but do from time to time have to open the case for other things so I check then as well

Thanks, I definitely will be cleaning the components in the box more regularly. I also have started going through some of the great tutorials on this site to clean the unnecessary files and bloatware. Cheers.
