Dv5t HDD issue?? Computer stops unexpectedly! URGENT! [ Edited ]

[Ugur]

Hey all. I have 6-7 months old dv5t model. It runs on win7 62bit with core 2 duo processor and together with hitachi model 250gb hdd. A few days ago, while I was streaming a video on youtube, it repeated a noise and stopped working. No mouse, no ctrl+alt+del, nothing. Only last screen and the noise. I had to force turn off. I tried to turn on the pc, it showed a black screen, no post and etc.. After several tries later, it ran again. But while I was showing webcam on MSN, it stopped again. It is repeating it every time. 

Previously, I had downloaded program together with trojans and my avg cleaned it. What are my options here? 

Thanks beforehand!

P.S. i tried to run HDD test using its own, it stops unexpectedly there too.

Call HP for a repair. If it crashes on the BIOS HDD test then you need to have them take a look at it. It could be the HDD, the HDD cable, or the controller on the motherboard.

thanks for replies, I've been trying different things with this problem... once it passed self hdd test, then it ran a full hdd test and hung, next time it didn't even pass the quick hdd test...it always passes RAM test without any problem.. I was told it might be problem of cooling... such as overheating...i tried to ran a ventilator(lol) and it still didn't help..but it was when it passed quick hdd test also. ill call hp asap...thanks...
