I have been working on this pc for a friend off and on for a while now. First one ever to stump me this bad. It's an HP 7840 that I upgraded the memory to 512mb and initially the HD went real bad, so I replaced it with an 80gig Barricuda. This system initially came with Windows ME. So we decided to upgrade to 2000 or XP.
The first time I managed to get 2000 loaded and udated and complete. Well during the process I ran across an error on startup twice, so I updated the bios. Restarted 20x's, nerer saw it again. Sent it with him, and as soon as he boots it up he sees it. Well it says that "If this is the first time you have seen this error, try to reboot your system again" Well he did, and no more problems for a while. The it finally crashed.
I get it back and format, and try to install XP this time. Well, after all of the files are copied and extracted and it reboots for the first time,the error appears and it will not reboot. Or I get "NTLDR missing"
The initial error is "STOP: 0x0000007f (0x00000000, 0x00000000, 0x00000000, 0x00000000, ) Unexpected_Kernel_Mode_Trap
Now at first investigation and alot of reading, everything pointed towards the memory. Memory is fine. Then I suspected the hard drive because it wasn't exactly new. Well I put in a spare I have here and the same thing happened. If I run some disk tests with either drive in this pc, they both show alot of errors on the drives.
I now have loaded windows 98se and everything was looking fine on updates, reboots, etc. So I shut it down for a day and when I rebooted, an error claiming missing information came up but windows did recover. The problem seemed to be with 98 only when it was shut down for a while. Now its getting more erratic. Sometimes on a restart. Windows claimed that the drive had bad clusters, so it started an examine, an it showed the progress and the unused,some used,used, and some bad clusters on the graphic. But it said 0 bad clusters.
I ambegining to think that maybe the initial hard drive damaged the motherboard when it went south initially. What could be making the drives loose information and act so erratic?
It's like they are real shaky with storing information. Also how common is it for a drive to have some errors or bad clusters on them?
Much Thanks!
