Hey everyone- I am wondering if anybody out there can help me… I have a Compaq Presario 700 (712au) and the hard drive crashed- I was advised by the computer shop man (hahaha) to dump it and buy a new hard drive - I did (more hahahaha) now I come home and try to load up and am having all kinds of misery. I have a 128mB of RAM and bought a Samsung 40gB 5400rpm 8mB cache HDD I have read many threads on this page and others and see millions having same problems as me (nothing new I am glad to see) but have tried all suggested solutions and none seem to be right for my problem (hahaha)! This is the issue. As I install XP (hahaha hysterically now) I get ok through the partitioning and format stages and then into installing but then my computer starts throwing up files it cannot copy from the cd- some can be done with retry some need to be just skipped! Then we get to the fun part, now I am in blue windows advertising efforts (love how they keep telling me how good they are when it wont even work!) of the install process - we get to about 37 mins remaining and then freeze up! After many attempts to gain ground I get mad - kick a few things and then reboot - reformat drive and start all over! This time it is a whole new mass of files cannot copy - ones that didn’t work before are fine now and ones fine before need to be skipped! Then we hit payload- I get through the install and get to a windows screen! I see the hills! I must be close! Now it says needs to reboot and then I think I am all fine! Then the pain starts anew! The reboot brings me to a black screen with the message “Windows Root>/system32/hal.dll. file is missing...please install copy of file i have tried ....chkdsk /r .... bootcfg /rebuild .... fixboot ..... fixmbr .... process as sugested in other forums and threads..... i have tried using a usb external cd drive to install from.... is it a compatibility issues with new HDD and old RAM?? Now I just cry and quit! Can you help me!
