Choppy operation and frequent short freeze ups

Question

My A505-S6965 has shown a sudden decrease in performance and refinement.
It's once smooth operation of programs and sturdy memory have now given way to choppier, slower operation with annoying freezeups occuring about 3x a minute. Sometimes there would be brief peridos of smoothness, but it's erratic nature is getting to me.
I tried a complete PC restore, but the issue ddin't dissapear, but remained, indicating the culprit isn't a virus or software.
My older laptop, with Windows xp, runs a lot smoother than this, and its hard drive is more full proportionally. Currently the laptop has just arrived at the depot and is being diagnosed, but why would something like this happen? Is it memory, a warped hard drive, or a flawed processor?

Answer 1

The people at the repair depot returned my PC to me, saying they couldn't find my issue, even after extended testings and diagnosis. And my problem remains. Slower load ups, and occasional "seizures". For example, when I'm scrolling through a web page, sometimes the scroll bar freezes a few sec, then, snap, it's at the bottom. I'm getting those a lot more frequently now, and freezeups where the screen styas still for a few secs, then starts again. And when I'm on WoW, the sound and video are often completely out of sync (it's not a game problem, it persisted after a complete system recovery). Loading of other programs is generally slower, with similar freezeups. This laptop could once handle many windows with ease, and now it struggles to do so. And the repair depot claim my problem doens't exist....It's hard to believe that this is the same powerhouse PC I bought in August 09, that made me a very happy customer for a few months. My older laptop with XP runs smoother than this, and loads faster than this, and it doens't have 1/4 the stats of this model. For a PC with 4GB ram, 500GB hard drive, and an ATI Mobility Radeon with 512 mb dedicated memory, this is simply a humiliating embarrassment.
I've since then upgraded to Windows 7, but little improvement has been accomplished by doing so. My words sound a bit terse, but that is because after a month of calling, lack of understanding, and so called "repairs", my patience is running out. What is wrong with my PC, and why won't Toshiba lift a finger to fix it under my warranty? Even if the way i describe the problem doens't quite fit the problem exactly, you'd think they'd have at least picked something up or noticed something wrong. Or do they simply think my problem isn't worth the trouble to fix? Or is there something I've overlooked? I've updated audio and visual drivers, and direct x, but is there more?
