Hi @Jamsarudheen, welcome to CF.How can I speed up my desktop's performance? please give me suggestions
It's very slow now. I have email, Whatsapp, browsing, Word, and Excel open at the same time for work.
Hard disk: 512 GB; RAM: 4 GB; Windows 10 Pro. Intel processor i5-3470 CPU 3.20 Ghz, 64 bit OS
In which case I'd definately suggest you start here in regards to upgrades.Yes, HDD is spinning metal disk
You will indeed need to ensure the RAM is compatible with your system.Yours will likely be DDR3.Can I simply replace the RAM myself by buying it from Amazon? When I call a technician, he said that the category of existing RAM should be checked before changing. Is that right? or I can change
