I have an Alienware M17 R2 with with Dual 1gb ATI Radeon Mobility HD 4870 in Crossfire x video cards.
It has frozen twice while playing a game and I had to do a hard shutdown. The third time it froze I was just on the Internet and I got the blue screen. It said video driver problem and to reinstall them. When I tried to restart the computer I got no video. Fans come on all the lights and dvd drive power up but nothing on the screen.
For the sake of it I tried the HDMI connection on another monitor with no luck.
There is no POST beep so not sure if it is even getting as far as the BIOS.
I think maybe something wrong the motherboard.
Is their a possible way to check these to rule out one or the other? I don’t really want to buy two new video cards if that’s not the problem.
Probably a driver issue, I had a similar problem on my desktop and it was caused by the Intel HD4000 IGP. I solved it by increasing the IGP voltage offset and deleting, then re-installing the latest drivers. You may also need to flash your BIOS to the latest version, if it isn't already on the latest version. Perhaps your laptop could be over-heating, too. It's hard to say, if you can't fix it, it could be a hardware issue. You might want to run Memtest x86+ or just take it to a shop.
First of all thank you for the replies.
I can't seem to test anything because nothing comes up on the screen, not even the post screen with the BIOS version. It does seem like it is booting when i start it though. I have never known a video card to do that. Drivers are usually a simple fix.
