IRQL error

my HP laptop developed some problem a week ago. suddenly it showed "Superfeth has stopped working" and then a blue screen came with memory dump and error message "page fault in non-paged area" and then restarted automatically. After that each time I started the blue screen came with error msg "IRQL_LESS_OR_NOT_EQUAL" and i was not able to work. I contacted HP they asked me to do hard drive self test and memory test .. all of which passed. Then they send me recovery DVD. The first DVD which reformatts hard drive went well;but with second DVD it started to reinstall everything the same IRQL error msg came with blue screen and computer stopped. Now I can only go into BIOS screem with F10 key. I can not enter safe mode or anything. If i start computer only black scren apprears and a blink on top left corner. HP is clueless if it is a soft ware or hardware problem. Please help.

FWIW: Black Screen (fixmbr) - http://support.microsoft.com/?scid=kb;en-us;314503

I suggest recontacting HP.

You didnt mention how you tested your RAM, so I will offer a suggestion. Use memtest. It runs outside the windows environment and can find errors that other tests cannot. You will need to go to their website and download the .iso file. Take that file and use a program like nero, freeisoburner, or imgburn to make a bootable CD. Switch your options in your BIOS so that the CD boots first. The program will run 8 individual tests. When those are finished you will get a message saying the RAM passed. If you get any errors, even one, your RAM is bad and needs to be replaced.

memtest download.
