Hi guys, I have a weird problem. I was saving pictures from Firefox and opening them in Photoshop, when suddenly Firefox totally disappeared. Then a minute or so later, Photoshop disappeared. After that, Explorer closed and said:

"The instruction at '0x7c910f29' referenced memory at '0xb7b7c6c6'. The memory could not be 'read'."

Any time I restarted Explorer it would say this, and now any time I try to browse for a file in Firefox (for instance, to upload something) it freezes the program.

I've tried restoring my PC to an earlier date, but each time it shows the progress bar and then at about halfway the screen goes black and leaves the cursor locked in the middle of the screen. After a while I decided to manually turn off the computer, and when it came back on it said it couldn't be restored to that date. I've tried a few others but to no avail. Now that I think of it, though, this computer has never been able to restart itself - it always goes black at some point and stays that way.

Any way I can fix this? I've looked all over the place and can't find any answers... just lots of questions about the same thing!

Thanks in advance!

Welcome to PC Help Forum

I am suspecting a RAM problem. Can you please download and run this: Memtest86.com - Memory Diagnostic - upon boot, from floppy disk.

It will take a long time but please let it complete...then post back the results here.

Hi, thanks for the reply. I'm having another problem - I found a problem called RegCure or something, and every time I try to download it in Firefox, it freezes. Then I told the Download window not to open when I download something, and it didn't freeze - then I opened the download box manually and it looked as if the file had been downloaded. But when I went into Task Manager to run the file through there, it said it couldn't be found. I then put the file on a CD using my Mac and I can't figure how to get it to run from there either. As far as the floppy goes, I can't seem to do anything so I don't think I could even get it onto the floppy in the first place

Hmmm...ok, let's put you thru the Pre-Work first..just to make sure we're working with a "clean" PC.

Hi there, I ran MalwareBytes and HijackThis and here are my results. MalwareBytes found a bunch of infections the first time I ran it, but because of my problem I wasn't able to save a logfile. Now I just ran it again and it found no malicious items. I also ran RegSeeker and fixed the Registry Errors it found.

Hey guys, MalwareBytes and RegSeeker are now showing no problems. What would be my next step? Would it be to delete malicious lines in the HijackThis report?
