7805 Display or video card problem? HELP please!

Dear all,
My 7805 gave a freezed display last night, when I reboot the computer, there is no display on the screen at all (absolutely nothing, not even the gateway logo ), the hard drive is running and the computer would even respond to my windows login password (if I type in the right password, the NumLock light would turn on and the hard drive would keep running for another minute, if wrong password is typed in nothing happens). I am guess the system is actually running and the only problem is in the display or the video card. I can change the brightness of the screen with Fn+arrow. There is no warning beep or anything at the startup. Anybody have similar problem before? Any advice is great appreciated. I tried external monitor but it picks up no signal either.
By the way, I am running RAID 0 on the computer, is there anyway I can read the data on the hard drive in another computer? Will any intel raid controller work? Thanks so much

 

Sounds like the symptoms of a GPU problem. Since an external monitor does not work, it just reinforces that theory. A solder reflow procedure by baking the motherboard may help here. You should be able to read the RAID array with another laptop that uses the identical Intel chipset and has dual hard drive bays with RAID support. I strongly suggest considering the baking method, it has worked for lots of people.

 

thanks so much for your help, I really have to think about actually baking the motherboard...sounds so scary...
