Ok I have an Averatec laptop model 4200 series, it had Windows XP Home Edition installed. The laptop worked fine when my mom used it and when I got it I started noticing that every once in a while there would be a lockup and I couldn't do anything on screen. Sometimes it would stay like this, sometimes it would be a program, and sometimes it would go to a blue screen saying there was a memory problem, I don't remember the exact error but it would say "Beginning dump of physical memory." Well, all I ever had to do was reboot and I'd be fine. Earlier this morning it wasn't closed all the way so I just pushed it closed like I always did, programs running and everything. I never had any problem closing it that way but when I went to open it it gave me a bunch of errors saying it couldn't save to a certain directory. Like, I tryed to open IE and an error said "Windows couldn't save temporary internet files to C:windows, please choose another directory" or something like that. I figured it was a simple mishap with the computer so I powered it off and powered it back on without saving any important information on my computer. Now, when I power it on, this is the error I get: Intel UNDI, PXE-2.0 (build 082) Copyright (C) 1997-2000 Intel Corporation For Realtek RTL8139(X)/8130/810X PCI Fast Ethernet Controller v2.13 (020326) PXE-E61: Media test failure, check cable PXE-M0F: Exiting PXE ROM. Reboot and select proper boot device or insert boot media in selected boot device and press a key. I have tried to fix it by formatting and re-installing XP but it would not allow me to format, it would say "Format not complete... The disk may be damaged" so I'm assuming there's something wrong with my HDD. I don't have a repair CD and this laptop isn't mine just yet. Please help!
