Windows 7: Irregular frequent Bugcheck BSODs first x124, then xa and x3b

fyi, I am an IT person myself, just not much experience in this particular BSOD problem.

I tried to download Drive Sweeper again, something else was installed (Zip extractor) and AVG says it contains a Trojan!

Okay, looks like I finally found which link actually downloads Drive Sweeper as a stand-alone exe. Geez their page is very misleading, most users would have trouble getting the actual file on their pc.

With driver sweeper, it should not install the add ons if you de selected them in the install process. I use it every time I change graphics drivers. Good to know you are an IT person. That means you know more than I do. The difficult part is the hours of testing to run down the faulty hardware. If it is drivers, that can easily be fixed. The easiest way to fix drivers is a clean install. It will save hours of running down which program or driver is causing the problem. But, I'm sure you already know that. If you back up personal info to an external hard drive, download drivers and the installers for the programs you want to install along with the activation numbers, A clean install is rather quick. Hardware takes a lot of hours of testing. But, the 124 BSOD is a general hardware fault, not very specific. It also does not necessarially mean you have bad hardware. A bad bios setting can cause it or a lack of voltage to the CPU will give you a 124 error. A bad ram stick will do the same and give other error codes also. For example, if a ram error causes the graphics driver to crash, the computer will give you a graphics driver error because that's the driver that crashed. When in reality it was the ram at fault, not the GPU driver. That's why it is so hard to run it down and so tricky reading the bug reports.

Driver Sweeper in Safe Mode. Select ATI. Click on Analyze. Nothing listed to clean.

The price of free programs. They make money from advertisments of other programs, and sometimes it's hard to find which is the actual program. It will still try to download other unwanted programs, but you can uncheck those options to keep it from doing that. It can be very difficult with the free programs.

OK, just skip that part then. I'm not sure why you get those errors then unless there is some program that is looking for an AMD driver and crashes because there is none. That's just a guess.

BTW< I assume you deleted the program that had the Trojan in it. I hope so. I would also complain to the site you downloaded it from, Guru 3D I suspect. They are a pretty reputable site. But, sometimes even the reputable sites don't check their advertisors.

tware, how's the computer doing. Have you reset bios to defaults? Are you still having problems?

Yes I did all I could and gave the laptop back, she will let me know if it happens again. Thanks for all your help. Did report trojan to guru3d. Realized that the ads that easily identify advertiser download links were being blocked by my ad-blocker, hence my problems finding the correct link. I just thought the utilities showing up in the installer were the paid ad-ons to drive sweeper! Geez... big time brain farting
