This is my neice's laptop, I am trying to help. Laptop started configuring updates from windows and got to 3 of 3. Do not know what updates. Computer suddenly blue screened. Now loops from Dell startup screen to configuring updates to blue screen. Stop codes 0x0000008E, (0xc0000005, 0x81E4B1A7, 0x8892991C, 0x00000000). Have run all diagnostics under F12, all pass test. I have the reinstallation DVD but will not read disc. Yet CD/DVD passed test and can hear it working. Also put boot file on USB but will not read from that. Will not load in safe mode, will not run debugger. I have no other ideas. Please help
