Computer Freezing problem

[Zangetsu]

Hi All,

I was surfing websites then suddenly my desktop freeze.
mouse was not working (bcoz its LED lights went off)
keyboard keys were not working (so cudn't use task manager)
HDD LED was not blinking.

but all Fans(graphic card,proccy,PSU,extra Fans) were working as normal...

what could be the problem.
RAM or HDD?

Config: Core i5 750
4GB Corsair RAM
500GB WD Blue HDD
450VX Corsair
Gigabyte mobo P55
Windows 7 Ultimate x64

Freezing problem can be due to many factors, HDD, PSU, RAM or it can happen because of windows itself.

Is that freezing frequent, if yes that might be because of some hardware , else t could be because of the windows.

scan HDD for problems...

remove the Ram(s) and clean the gold pines gently with a eraser and blow some air over it with u mouth reinsert it and perform a Memtest 86+ for 2o mins atleast i highly doubt it the RAM. reply us the results as soon as u try it
hope that helps

I would suggest before doing anything scan the HDD's also try running live ubuntu & see if hangs there

[Zangetsu]

I m also sure that its either HDD or RAM....

but if HDD has a problem...will it freeze the system & goes to off mode...

HDD doesn't have bad sectors...AFAIK

^ thats possible, IO error can led to system malfunction (crash and hang)

[Zangetsu]

^but after restart it works fine...
the freeze is intermittent

^ If its not frequent. then that might be due to some software issue as well.

It could even be because of some nasty virus. Wat AV are you using? Run a full system scan and check for any infection.

yes..but HDD going to sleep mode due to virus & software is surprising

I m using Bitdefender Internet Security 2012

^ your HDD maynot be sleeping

Just run a complete scan to be sure

Can you restart.
If so when windows starts you will get a prompt saying that windows had some problem and then post the info on that dialog box here.

The PC is working fine from last 2days...
but I have kept it under observation.

^ then the issue might be some software bugs or some windows (regular) issues
