very high physical memory usage.

[sambourne]

Hello,

I have a Dell XPS 15 laptop with the following specifications:

intel core i7-2630QM quad core processor.

4GB RAM

Nvidia Geforce GT-540M graphics card with 2GB memory

500GB hard disk

Windows 7 Home Premium 64-bit

Earlier my pc was clattered with a load of junk stuffs that eats away physical memory and cpu usage. Still before this problem came up, the physical memory usage was arnd 44-45% and cpu usage was 10-12%.

Just 2 days back while I was working with it, i inserted a pen drive and the pc was unable to recognize it. so i reinserted it nd it was again working. bt since then the pc started to lag very much. when i checked task manager, the physical memory usage was around 88-90% and cpu usage 30-32 %. Something like this never happened before.

So i restarted my pc but without any success. Just after restart, the memory usage was above 90%.

Being fed up with this, i formatted my partition with windows. After successfully reinstalling windows, the computer was back to normal again.

everything was fine until i opened my other partition disk and installed 2-3 softwares. At first i installed adobe flash player, but nothing changed. then while installing adobe reader, again my pc freezed. the memory usage was again around 90%. it was hell back again.

but thankfully i had a restore point made after my windows reinstalled. so i revert back to the restore point. and again everything was normal.

thinking of this as a virus problem, i installed my mcafee av and scanned through. 3 virus and 4 trojans were found and fixed.

again i went to my other partition and installed 2 softwares. this time those were vlc player and powerpoint viewer. vlc player installatn was fine but while powerpointviewer installatn, the lags happened again.

i restored back to the initial point again.

this problem is giving me a big headache as my laptop is a new one and i am unable to use it for good. i think the problem is in the 2nd partition of my disk. coz while installing drivers and other softwares form driver disk,there were no problems.

i was thinking of formatting my 2nd partition but many valuable files are there.

please, someone help me out of this as soon as possible.
