And u think ssd will solve noise sound problem?..
The noise comes from Your hard disk recalibrating the servo that moves the read/write head. It does this after a certain number of reads or writes. (In other words, the noise means Your hard disk is super busy.)
About half the reads and writes in a decently configured system are from virtual memory. A poorly configured system (with too little RAM for the work load) can overuse virtual memory.
The cheapest solution to take load off Your hard disk is to add a small and cheap SSD as I described.
Another solutions might be to replace Your hard disk with an SSD, but that involves a big, expensive SSD. This is the upgrade that would be the most expensive and that would yield the best results.
Yet another solution is to increase the amount of RAM in Your PC. 8GB may be enough, or it may not. Adding RAM may help, or it may have no effect. Start the TASK MANGER, and click on PERFORMANCE. See how much "MEMORY" You are using. If You are using no more than 1/3 of Your physical RAM, You are good. If You are using more than half, You would benefit from more RAM.
The weird thing about Windows is that it uses virtual memory when there's no need to. Even if You have tons of RAM, Windows still works Your hard disk moving things out of RAM and to Your hard disk, then back again. An SSD is made to run thousands of tiny reads and writes. Hard disks are not made for that kind of workload. Using a hard disk for virtual memory can do amazing things to a system's performance.
