Why not check your harddrive with something like crystal disk info to see if there are any errors?

Also, try a bigger powersupply if you can - maybe from a friend for a few hours.

Could also be that there is a Motherboard / BIOS issue - is the BIOS revision recent?

[Dr.Sinister]

I checked the harddisk its fine might be power issue and i havent checked the bios version,the whole thing happened when i played forest beta at high settings and when the gpu took more load everything went slow i removed the harddisk and booted with my asd faster and no problems when i connect my hdd so slow and today i formatted my whole harddisk and everything was back to normal but i am scarec if i give too much load to gpu my Harddisk cud fail again

Try a "better" power supply, not necessarily "bigger".

[Nixblicker]

I agree with Quaker - I have actually never heard of Zebronics - I would go for a PSU from a Company like Corsair, SeaSonic, Coolermaster and the like, with a bronze rating or higher.

Thnks guys it was the power supply issue i am gonna buy a coolermaster b600 or a corsair cs650m,thnks quaker and nixblicker
