Solved Suddenly Very Slow Windows 7 laptop


Thread Starter

Hello. You'll have my undying gratitude if you can help me solve this--I feel like I've been flung back to the days of dialup modems.

My PC is a 7 year old Lenovo e530c laptop, Windows 7 64-bit OS, SP 1. Two years ago I updated RAM from 4 to 16 GB, and upgraded HDD to a 500 GB SSD. Since doing that, this machine has been very fast. Installed apps I use a lot, like MS Office and several audio editing softwares, start immediately and I can have several app windows running without any noticeable delay.

Our internet is Verizon FIOS 100 MBPS, so with the SDD and RAM upgrades, about anything I do on the web is pretty much instant response, maybe 1-2 seconds max. Youtube livestreams in HD open and play with 2 seconds. I can watch full movies on Youtube, and stream DirecTV on demand with no problems.

Until three days ago...I left my PC and was away long enough (maybe about two hours) that it went into Sleep mode.

When this happens, normally just a mouse move or tap on keyboard is enough to wake it up, but this time when I returned, the PC was powered down. When I booted again, and the main screen came up, I saw immediately I had an Edge browser icon in my taskbar. I run mainly Chrome and Avast Secure browsers.

Don't want any part of Edge, so I uninstalled it using the Control Panel Programs and Features uninstall. That's when I noticed how slow everything was running.

MS Office apps are now taking 20-30 seconds to start up and are slow running. But main issue is anything on internet. Simple pages take 20-40 seconds to open, and anything complex like Amazon will take up to 1-2 minutes, if it doesn't timeout first.

At these times, Task Manager performance monitor shows CPU is pegged at 100% while usage of 16 GB RAM never exceeds 6-7 GB.

Specific things I"m seeing when trying to open websites:

1. "Can't resolve host" warnings in lower left area of browser.

2. "No internet" screens after 30-60 seconds trying to open pages, with messages like

This site can’t be reached
or’s server IP address could not be found.

While at the same time I'm sitting there with my iPad connected to same Wifi router and Internet service, and it is flying.

3. Odd URL when trying to open Google: instead of seeing just, it is now Never saw that before.


I ran Avast full virus scan, found 4 "malware threats" that I moved to the Virus Chest. No improvement in performance.

Thanks to all of you who looked at my post and considered replying.

The problem is solved thanks to MisterEd51, who PMed me to suggest that I try reinstalling the Edge browser. Apparently Edge can't be uninstalled cleanly from Win 7 via Control Panel/Programs and Features, and whatever's leftover hangs up the system.

Once I reinstalled and rebooted, performance is back to normal.

Kudos to MisterEd51:love:
