Cannot complete clean install,....

About a week ago my wife got on the computer and noticed oneof her folders was missing. She tried a restore point and she couldnt locate a restore point. After about 15 minutes of looking for the folder the screen went black. She tried moved the mouse and figured the screen would come back up but nothing. She finally did a cold boot and then got BSOD. I get home from work and immediately try to boot and get either BSOD or it would freeze at a black screen. I tried safe mode and every other option there is posible with in the OS and nothing would load properly. I then said screw it and tried to load my recovery disk and again it would freeze up. After numerous times of this i finally ran wipedrive and was gonna try a clean install. Wipedrive ame back with 100% wiped and the i ran to check for errors/dirty sectors. They both came back good. Tried my recovery again and it keeps freezing. I have tried numerous HDD testers and they all freeze up on loading. But i do get a quick glimpse of the creen and it says "illegal partition table" about 12x. Now i get random pixels on the screen and there constantly blinking. I took out my video card and used the onbaord video to verify that the video card is not fried and its the same. Im lost ......i believe my hard drive is fried. I dont mind getting a new one but dont wanna buy one then it turns out its not the hard drive. Also its a WD 640G, when i ran wipedrive it only shows that it wiped 596G. I am lost....PLEASE HELP!!

update: I have been able to load WD Data Life on a USB. Extended test came back good. Now its running media scan. Any input would be greatly appreciated.

Anyone?
