I've consulted help about large CPU memory spikes and CPU crashes that leave Internet Explorer freeze hanging and unable to close after the browser tab memory peaks over a certain amount. Its a little random when this happens and has made using Internet Explorer difficult, and the CPU hasn't had this problem before.

 

I've been through two two topics of good help already:

 

 

https://www.bleepingcomputer.com/forums/t/646160/found-trojanagent-gen-dropper/

 

 

https://www.bleepingcomputer.com/forums/t/650004/multiple-iexplorerexe-and-schvostesexe-2-the-electric-boogaloo/page-2

 

So far, it doesn't look like any Malware is involved, been through several scans. What lead this to the topic was the last expert advising that the CPU Speccy  had suspicious SMART values. Is there indeed something wrong with the CPU  afterall, or is it something else, or nothing at all?

 

Thanks for any help, all the previous help is very much appreciated also.

I've scanned through your previous posts and there are some red flags. First, Firefox will not load or open. There is no reason that should happen if it was correctly installed. Would you please try installing any other browser just to see what happens (Opera, Chrome, Safari, etc)?

 

Second, if I understand correctly this seems to happen somewhat randomly. Needless to say that makes it harder to diagnose. Can you please boot to safe mode with Networking and see if the same thing happens there? If it does, we may be looking at a hardware issue.

 

And just so I know what you've done so far, have you run diagnostics on the ram and HD?

First up, I still have the previous topic open, I am not sure if that is ideal or not. I'll try another browser, see I that works. I've noticed Firefox does open now, but is more prone to crashing and large memory spikes. I'll try out Safe mode as well.

 

I've run a couple of dskchks that don't turn up anything but some reparse files and if I can recall, a few orphaned files. Yet no bad memory or bad sectors. Otherwise, no other diagnostics checks.

Let's check the ram: download memtest (http://memtest.org/). Burn it to a cd using a dedicated .iso burning utility (http://www.petri.co.il/how_to_write_iso_files_to_cd.htm), make sure the cd drive is at the top of the boot order in bios, then boot to the newly created cd and run the utility.

Tried out Safe Mode with Networking. IE was still bad with the memory usage, though the Physical Memory was much lower and ran smoother, but then it was in safe mode. Still spiking high, but no freeze hangs or crashes even when it got too high.

 

Firefox went crazy in Safe Mode with Networking. Had trouble loading, very choppy, kicked memory up way too high way too fast. Thankfully, no freeze hangs or crashes. I've yet to try out another browser.

 

I'll see about the next step also.

Sounds like a hardware (or malware) issue. Please go ahead and check the ram.

Still working on it, once I have cds that aren't CD-Rs and are CD-RWs, and the CPU isn't giving any trouble.

CD-R versus CD-RW should make no difference.   The first is writable only once, then readable "forever" while the latter can be rewritten multiple times and then be readable "forever."  [No optical media that's burnable actually remains readable "forever" in practice, but it should be a very long time.]

Haven't forgotten, only things have been piling up and the CD-Rs I thought I had are already finalized or turned out to be DVD-Rs instead. I may have to go out of my way to purchase some.
