Windows 7: Completely random freezing issue

Hello.

I need some help. I've been tearing my hair out for months and nothing has working.

The Problem: Random freezing/hanging of my computer. Screen is frozen in place and a continual audio buzz is heard. Only way to solving is with a hard reset.

System:

Asusrock: M3A770DE
Ram: 4GB DDR3
GC: nvidia 450gts

Tried and failed:

New hardware for ALL components except processor. I have already eliminated:

- PSU
- Overheating
- RAM
- Virus

I have a strong suspicion that it is related to the sound drivers in some way. Some sort of driver conflict.

Note: The freezing happened for 6 months constantly, but then suddenly disappeared when I cleaning my graphics drivers with driver sweeper - I had an ATI card at the time. Then, one day, the freezing just started again out the blue. That's when I purchased a new graphics card, but it is still freezing. Done the driver sweeper several times but no luck.

Sorry about the poor formatting of sentences...had to write quick before the big freeze :S

If you are suspecting drivers, but have no dmp files to show us, download and run DriverView from Nirsoft. With the DriverView window in focus, select all (Ctrl+A) then File > Save selected Items. Save as a txt file and attach to a post. If you get the chance, cut the viewable columns down to : File name, installed date, modified date, that's all that's needed.

You can also run a command prompt and type in driverquery which will give a list of currently "in use" drivers.

Thanks fimble. See text file attached

A quick run through of your drivers list reveals this outdated Realtek LAN driver.

Thanks again. Updated the to the latest drivers but still freezing.

Getting a Kernal-Power 41 (63) - unfortunately I know this doesn't really tell us much

Don't know what else to try. Thinking about buying a new computer as need it to run my business.

If anyone has any other ideas, please let me know.

Many thanks,
L

Update

This is now solved - it was another corrupt ram stick. That's two lots of brand new dodgy ram - guess i'm just unlucky.

At least PC fully functional again.

Peace,
