I've spent the last 3-4 months trying to figure out what is making my laptop run so slowly. It first started out as simply trying to get a smoother streaming video (Youtube videos are like picture slide shows, it's infuriating). And I can't visit more than 10-20 pages before I have to delete my history/cookies and all that because it slows to an absolute crawl. Then I noticed that the System Interrupts were double the average (85,000ish to my 163,000ish). Even at Start-up without opening a single program it still revs up the CPU to 75%. I ran AVG, Malware Bytes, AdwCleaner and even ComboFix (I know I need "supervision" to run that but frankly I don't care anymore, if I've irrevocably ruined this computer maybe I'll start doing something productive). So it's not virus related. It's not processor/system services related either as I've checked Process Explorer/Procmon. Speed Fan showed the CPU temp to be normal, in the 90's F. but the two processors (Intel Pentium something, the Arrandale one) were on fire at 165 F each. Obviously it's pretty hot to the touch as well.
After scouring every corner of the internet all I could find was something about processors not communicating properly with drivers so I did everything I could to figure out what the issue was.
Running a Windows 7 hardware device troubleshooter turns up a detection of "Hardware changes might not have been detected." No fix.
I dropped it off of my bed after a night of bar hopping and now it has a thick white strip and a thin yellow strip going down the middle of the display. This was a year ago which is about the time I noticed over-heating problems/maximum fan usage. I disassembled everything to clean out dust and noticed that a wire that went up to the monitor looked like it was hanging on by a thread. Maybe it got yanked somehow in the fall. I also cannot update the Intel HD Graphics driver via Windows Update or by downloading it manually from the site.
I disabled a few drivers and the one that seems to be causing the System Interrupts is the Intel Series/3400 Series Chipset Family USB Enhanced Host Controller - 3b34. When I disable it however I am unable to use my Wireless Mouse and it's way too convenient to give up. I uninstalled it and restarted to let Windows re-install it but the massive amount of Interrupts came back.
I also had an issue with my Power port where a friend had to re-sod it. I guess the heat melted it to the point that I constantly had to rearrange the cord to keep it charged.
Now I'm stuck, what's next?
