Pc hang-ups again?

Argh...my pc is acting crazy again the reason why I can't grab any opps last night. While refreshing my triple P dashboard my pc suddenly shut off and when i try to open it to my surprise I did not see anything in my screen so I start to panic. Tried to re-start it many times but to no avail. This morning I decided to bring it to the technician. Asked him to clean inside and check what's the the problem on my pc and he found out that the cable that connect to the hard disk is broken. For the meantime he tried something to make this pc of mine work for this evening though I need to re-start many times cos it always hang.
