Laptop is very slow.

I've a laptop Acer Aspire v3 551G
It has:
ram: 6gb DDR3
processor: AMD a6-4400M 2,70 GHz

Since yesterday my laptop very slow, I was getting hard disk errors, I thought it was a virus so reinstalled the OS(Windows 8 64x) which took 4 hours to get installed. And still have the same problem even to go to my desktop takes arround 2 mins, Windows was telling me that there were some problems with my harddisk and asked me to make a backup. Also got this O/I error: 0x00007fbf18ae8555

Can some body help me with this, whats the problem here?

HDD is probably failing, run the HDD manufactures diagnostics to confirm.

Ok I ran "chkdsk" like this for c drive since thats the only partition i have:

After the scanning there were no errors found.
.
However my laptop is still slow and it still gives a harddisk error when OS gets loaded..

I believe something is wrong that is not software because reinstalling Windows should have solved it.

Are you sure your processor fan works? Does it make the usual noise when the fan runs as the processor runs hot? Can you feel there is hot air coming out the vent as the fan works?

Also Windows checkidisk is not very good. You shall download a bootable CD (or something that loads from a usb key) from HDD manufacturers site.

@Smallfilou the Laptop does get very hot and yes the fan makes alot of noice.

In that case, especially is the fan noise is ireegular, rattling or else, you shall open up your computer and see if there is a dust buildup.
Maybe you will have to change your fan:

but it looks difficult on your laptop: no direct access to fan... Good luck!
