Again, I don't possess a disk drive.

Can you boot from a USB flash drive, or borrow an external CD/DVD drive?

I'd like to refer you to my pervious post that states I would require a Linux OS dual-booted with Windows. This is the only USB option available, as indicated in the page you linked to providing Memtest downloads for all available versions.

I do not have access to an external disk drive, nor do I wish to install a second operating system.

I don't understand what you are saying here. You mention Windows 7, Linux... Is this a Netbook computer?

I have a laptop computer with Windows 7 and no disk drive. I can't borrow an external drive from someone.

The Memtest page you sent me to says the only USB bootable Memtest version available requires Linux to use.

Memtest doesn't seem to be an option. Where do we go from here?

You don't have to install Linux... Linux code will be used to create a bootable Memtest86 flash drive. You boot from this flash drive and Memtest86 will start. Let it run for at least 7 passes

Although I explicity stated that I didn't want to use my sole USB drive for this purpose, I tried installing via Linux Live USB again (I had done this in the past with unsavory results). My USB drive, which is a couple of years old at least, has something wrong with it and LiLi refused to respond shortly after extracting Xubuntu 11.1 to the disk. The last time I did this, it at least installed correctly and everything was fine until I ran the VM and was actually inside the GUI. It, at this point, began the "not responding" fit and I stopped using my flash drive for this purpose after wiping the drive and trying it again a couple of times.

To make a long story short, I'm unable to use Memtest with my current supplies. I'll ask around some more to see if I might be able to obtain another USB drive, if only temporarily, to complete this task.

In the meantime, what other steps might I be able to take?

You're making things very difficult and I don't have any other ideas at the moment... Good luck

Excuse me? I'm the one making things difficult? You have repeatedly proven that you haven't read my posts with the attention they should have been. I did everything you asked and even explained some things to you more than once. If it was so difficult to understand, perhaps you should have read my previous responses again and/or probed properly instead of giving default instructions based upon how you think things should be.The only thing I was "being difficult" about was being physically unable to run Memtest on my machine and I even just stated that I would attempt to get my hands on the required hardware.

I'd advise you to be more attentive and respectful in the future, else don't give some half-@$$ed attempt at helping someone.

Thank you for your massive fail and especially for wasting my time, douchebag.

You don't have to be insulting... Flash drives are cheap and easy to obtain. You don't have to install Linux to be able to setup a bootable Memtest86 flash drive. There is nothing more to do except maybe a hard drive check

Nope, I sure don't have to, but unwarranted and erroneous comments such as "you're making things difficult" make me want to throw one or two back at you.

Thanks again
