Hi Bleeping Computer....

Right now I have a serious problem on my notebook....

My Notebook is HP Probook 4421s

 

 

Here are what happens before it goes completely mess right now....

1. I was surfing on the internet, when suddenly a notebook pop up, and disappear again (this is what i suspected to bee the root cause of the problem)

2. then I continued surfing as usual..after about 1 hour, my screen started to scramble "a little bit", then it goes blank for 1 second, then a pop up on my bottom right screen says something about "disk driver has recovered......"  

3. i don`t know what to do, then while I`m searching how to fix the problem, it happens again....

4. it happens about 3-4 times. At the last time, the scrambled screen become worse...

5. I decided to do "system restore", but after restarting, it goes to completely blank screen

6. i turn off the notebook, wait about 15 minutes, then turn on again, still only blank screen

7. i read about "hard reset (15 minutes hit power button while unplug power cord and battery", still blank screen

8. try, 2-3 times, i give up, and wait until tomorrow (today)

9. then i try to turn it on again, the screen is on, showing some vertical thick line of scrambled screen. i can hardly read what the screen is showing, but it still fail to start up the windows...

10. I try to hit F10 repeatedly, then it comes up to some page (hp back up system? with hp logo on bottom right), then it shows some menu, i choose something like "run-in test", it has run for about 30 minutes, and i just wait what happens next...

 

 

My question is : is it hardware or software problem (virus???)... and would you assist me to fix it ?

Thank you very much... =)

It looks like it's hardware. "showing some vertical thick line of scrambled screen"

 

Are you able to see a screen like this (BIOS boot post screen)?

Please post some screenshots of your issue. (If possible) Try to post also the screen like above if possible.

i`ve sent it to HP service centre, and receive reply that I must buy and replace the part named : SPS-BD SYS 14.0 DSC 6370, which is very very expensive... =(

 

what part is that ?

is it the only solution ?

 

or any other solution SHOULD I try before I execute the advice of HP service centre ?

 

if there any other solution, I probably need the step by step instruction, because my notebook seems not showing anything on the screen...lol

 

right now, i plan to call back my notebook, and see if there any other solution available...

 

Thx for the help =)
