Hey guess i'm new but we'll save that. So my laptop (compaq presario, 1.5 years old) was running very slow and choppy i ended up defrag etc. and ended up getting the blue screens of death. It was at the point the computer would work for 5-10 mins then BSOD. SOOO I reformatted totally wiped the hard drive etc. and did a fresh install of xp home (i was running pro before). Anyway, that went fine and I thought I was in the clear. Next thing I know same thing same BSOD: 0x000000F4 (0x00000003, 0x8244CDA0, 0x8244CF14, 0x805C749A) While this happend for awhile, i began to get upset. Now the laptop is doing the PXE-E61 check media cable blah blah.... Long story short..I took it to get serviced..they told me nothing was wrong with ram OR the hard drive (wow thanks) Then out of spite I took it somewhere else; the guy there basically just used an HD of his and installed XP and said..well it looks like a new HD is what you need. Tried that, but when I installed it...I still couldnt' get passed the media cable errors (which he didn't even have). Yes i've tried changing boot orders etc. Weird thing is..sometimes it will load windows...othertimes it won't? And usually when I try to install windows it says no hard disk found blah blah F3 to exit Furthermore, in bios 9/10 times it will say NO IDE found for the diagnostic test, and only one or two times have I been able to run the test, both times giving an error something along the lines of: #2 - 07 fail? (which i'm assuming is a problem) So with this all said...its off warranty...what's wrong...I need this thing fixed. I don't want it to be the hard drive controller.
