Dell Laptop running very slowly
Hi,
I am trying to find the faults on a friend's Dell Latitude D531 running Windows 7 Home Premium 32 bit.
it is fitted with a AMD Turion 64 X2 processor and 4 GB of RAM.
The laptop is running very slowly and taking a very long time to boot into Windows 7, but although it is slow, everything seemed to be working fine - hardware and software.....
Unfortunately, my friend did not have any Anti-Virus software installed so I suspected virus and/or Malware infections might be causing the problem. I ran several Anti Virus programs (one at a time) and Anti-Malware programs to try to find any 'crap' but only found a few 'PUP' programs, which have been removed.
Looking at the the 'performance' graph in the 'Windows Task Manager', the CPU Usage often tops out at 100% even when it's not performing any really intensive tasks - for example, just opening a blank browser page.... So I decided to re-install Windows 7 Home Premium +SP1 from an ISO DVD which I have used successfully in the past. Everything went as normal with the re-installation, but the laptop is still running Very Slowly - particularly when accessing websites - and the CPU still frequently tops out at 100%.
My broadband speed is good at around 14-15 Mbits and using my own laptop to access websites is blisteringly fast.... so there is no problem with my Broadband or router.
Thinking that despite re-installing Windows 7, there may still be some kind of Malware lurking on the laptop, I carried out scans with AVG, RKill, TDSKill, Spybot Search & Destroy, MalwareBytes, and Ccleaner. Nothing was reported by any of these programs..... I have also carried out a full Memory test and there were no errors reported.
When starting Windows 7, the boot process is taking around 5 minutes during which, the system just sits at the 'Starting Windows' Logo screen with no hard disc activity for about 2 minutes and then continues to load Windows. The System Rating is showing a Windows Experience Index of 1 !! I've never see such a low value before !
I have tried everything I know to try to overcome this problem but have been unable to find a solution. I would be very grateful for any help/advice while I still have a few strands of hair left !!
