I am working on an Acer Aspire 5100 that will not boot into Windows XP, safemode, ERD Commander or UBCD4Win. There is never an error- the boot process just halts. When trying to boot to XP it stops at the splash screen. When trying to boot to safemode it halts while loading drivers. Memtest shows bad memory but I have replaced the memory and the results are the same.
Any ideas what is going on or where I should go from here?
