yesterday I was playing on my Win 7 laptop when suddenly my screen went into this colorful faulty state, something of this
, though not exactly. And a second after my laptop died starting itself up again with black screen.
Now here's what happens when I try to start it up:
- Fans turn on for a brief moment
- CD drive can be heard
- HDD led together with other LEDs turns on, but goes black after a while
- Monitor remains black the whole time, doesn't even light up, it's straight turned off
- After a moment of that state PC shuts down again to restart and so on
NOTE: Even if I try to hold the power button to turn it off, it will start itself up again, unless I take battery out and remove power cord.
(I don't get any beeps or anything so I assume I either don't get into or past POST?)
I had similar problem some time back, but the guy that fixed it for me didn't really go into detail as to what was wrong or how did he fix it. All that he told my mom (who picked it up from him) was that there was a virus and something with the HDD. But he fixed it without changing any of the components.
Is it possible that it's the same cause again? Though it seems to me like it would be a mad coincidence to be or some software that I used both now and then that caused it...
EDIT: Can anyone relate or know what I could do to fix it?
My laptop: Acer Aspire 5742G (Windows 7 Home Premium, Intel Core i3, 4 GB RAM, ATI Mobility Radeon HD 5470)
UPDATE: So I've tried removing major components and checking other stuff in the process, with the help of someone a bit more competent to do it than myself. It seems that none of those components are the problem and the guy that's more knowledgeable about that than me thinks, that it's probably the mbd - more specifically the BIOS chip.
UPDATE: I removed my HDD and connected it to our desktop PC, wanting to save my data. Interestingly enough, when I try to boot the PC will let me choose between booting normally or going into the System repair/recovery mode (sorry my PC is in different language, so I hope this is the correct name for the tool) - if I choose that though, the PC will probably fail to enter it and goes back to that menu. If I try to boot normally PC will go into the 'Starting Windows' stage and then reboot. Coincidence? Or is my BIOS just wrongly configured? It seems to recognize my HDD though..
UPDATE (15/7): Curious thing happened. I disassemled my laptop and put it back together after cleaning it up a bit and now when I turn it on, it doesn't reboot - though my monitor is still black (I only tried it without HDD inside so far). Inside I also found the screen cable to be in... questionable state. Can't tell if downright faulty but it didn't look exactly a-ok. But if the cable is the cause, isn't it strange that it stopped working all of sudden and likely from several different causes?
