Hi, 

I have a huge problem with my M17 R3. I was on holidays and one day i get BSOD. I though when I came back I would run it from flash drive or DVD to check but even with that option BSOD still appear and I can't do anything at all. There is some more strange thing. When I leave laptop for a while like 5-6 hours and turn it on system runs almost normally to the desktop but after a short time BSOD appear and start all over again. I thought also that is faulty hard drive so I've unplugged it and run from flash. Even without hard disk when I run installation from flash i get BSOD. I've check also if RAM is not a problem but it is not. I ran also diagnostic of dell after hit F12 at startup but everything there seems to be allright. I just don't know what to do. 

Most time I get this BSOD: IRQL NOT LESS OR EQUAL but when it goes to infinite loop I get also another one - each time when reboot shows another BSOD.

I'm completly stuck at this moment and no idea what to do. For me it seems to some hardware issue...
