my PC specs:
CPU: Pentium ® dual core cpu e5200 2.5ghz
System type: windows 7 32bit
video card: Nvidia GeForce gt 8600
i know these specs are not good and cpu is pretty old too but until now I had no problem with that.
i built this PC 3-4 months ago with absolutely new not used cpu,gpu.. i'm simply using it: working with Photoshop ( i'm graphic designer ) and playing simple games like: Lineage 2, PES 16, mount and blade and etc.. 3 days ago i decided to install 64bit windows 7 as my cpu supports it and i could use more programms and games and maybe install more 2gb ram so i bought disk and installed it fully. After installing i noticed that my computer was really slow i was waiting like 30 seconds to open folder or google chrome and i'm not talking about games... i thought it was because of my cpu so i decided to install 32bit again. i installed it and i noticed that everything was OK now folders were opening pretty fast and had no problem with other simple tasks.. i downloaded PES 16 and started to play it .. i was playing simply first 10 minutes with 40-60 fps but after 10 minutes i started getting 1-5 fps only so i checked task manager and noticed that pes was using all my 100% cpu i paused for sometime game then started to play it again and same happend afer 10 minutes my cpu went to 100% usage again... after that i just closed the game and noticed that not only while playing PES but doing simple tasks like opening chrome or extracting winrar i was getting like 60-70+ cpu usage and it never happend before ..
1. i scanned my computer with malwarebytes but it detected no malwares
2. i cleaned it with CCleaner but it didn't help at all.
3. i defragmented disk but it didn't help too.
4. i cleaned my hardware with vacuum cleaner but still nothing..
i can't upgrade my cpu,ram or gpu because i don't have money now so i decided to ask for help people on forum... please if anybody knows the solution help me thank you.
