O I'm sorry man, I totally forget about that problem.
Here is my quick input.
Ok 1st things 1st, make sure everything is in nice and tight, now, as to what you was asking in your last thread here is how to check your disk
Start/Run>Type: CMD now black screen, now type CHKDSK
Now it will fly threw your harddrive and check it, report back to me if it has bad sectors or anything bad as it will tell you.
Also, sound cards sometimes crash computers, if you have lots of sound cables coming out here their and everywhere and have a sound card then if you nudge it it could just freeze and will make it sound horrible out of the speakers, my friends pc freezes like yours sometimes because he moves the tower by mistake and it can just touch his sound by abit and make it freeze.
Also you can DIAGNOISE your pc with some tools:
I have not used one of the internet so you can choose:
Also you could download cCleaner and scan your registry and your pc and clean them both up.
Also you could run it in safemode and just have a genral scan and check it, and also you could defrag it.
I'm sorry about leaving it blank on that thread you made, I forget about it lol.
