Windows 7: PC slowing down

PC slowing down


Since yesterday, my PC is slowing down intermittently.

Slower to open web page or do different task. Even the mouse movement was affected yesterday. Mouse was moving slower than it use with my first PC 30 years ago.

Everything was normal until yesterday. I replaced the main board last week, but replaced it with the exact and same model. All was OK after.

System seem slower when many task opened at the same time. Not unsual for me since using my PC. I'm running nothing more than what I use to.

Did check or pass
- Malware Byte / SuperAntiSpyware
- Kaspersky
- Process Explorer
- Crystal (Hard disk )
- Corsair Trim ( SSD)
- CCleaner

System was slow also after loading in safe mode (that could be normal)

Include report from Process Explorer

Any hint appreciate

You can try a System Restore to a date prior to the issue - System Restore
Try loading defaults in BIOS.

Hopefully this is the correct forum for this. Apologies in advance if not. 1. My PC has started to slow down (Dell Laptop Inspiron 1720, 2G RAM, Wini 7 Professional). This is odd because it has been pretty quick until this week and all of a sudden it's sluggish. Any ideas? 2. Ad-Aware...
