Windows 7 Unresponsive and fairly laggy

[ThePolishDude]

Hi all! I'm fairly new here, and I'm having an issue with my PC, and was wondering if I could have a lil' help.

I bought this computer three months ago, and had no problems, up until now. It all started with it freezing up all of a sudden, forcing me to restart. But the display didn't show up. Tried again. Didn't work. Eventually, I removed my GPU and placed it back again, thinking it was loose. Then it finally worked.

Then it happened again. So after taking out my graphics card twice, it finally started working, but my HDD started making strange sounds. A sound I've never heard before, and only occurred during start up. I shrugged it off.

Now I start getting these sort of instances, when what ever program I have open, stops responding and Windows get's pretty laggy. The Windows Explorer (Not IE, the tool bar thing) also is unresponsive. I know it can't be a virus, Trend Micro showed no signs of anything after I scanned my computer a bunch of times.

So I did what any sane person would do, I did a bit of research on the net, and found this thread on this forums. The person here had a similar problem that I did. After reading most of the comments, I downloaded HDD SMART, as instructed, and apparently "Current Pending Sector Count" is yellow.

What exactly does that mean? According to Wiki, it's bad. But that's all I know. How do I fix this?

Any help would be much appreciated!

PS: The I filled out the system specs form, as instructed

The disk is on its way out, backup your stuff asap and if still under warranty then start a rma process.

Thanks, this was the sort of conformation I was looking for. Just sent out an RMA request, and hopefully I'll fix the issue.

I'll post again later if this ends up to be the HDD.

Good luck!
