Save me! First time poster here, apologies if this was posted in the wrong thread. I'm in a certain harsh situation right now with my computer. I find myself to be fairly fluent with PC's, teaching myself everything pretty much, but right now this is something that I, along with countless hours throughout forum threads, can't seem to fix. Heres my system in a nutshell- ASUS A8N-SLI Deluxe Mobo Nvidia 7800GT card 1 gig ram AMD Athlon 3500+ processor 1st SATA WDC WD5000KS-00MNB0 2nd SATA WDC WD2500KS-00MJB0, not using a RAID controller all updated firmware for everything... The story - My system has been running, for the most part, flawlessly ever since i built it about 7 months ago, minus a couple drawbacks. I had been doing some routine downloading/multitasking, nothing out of the ordinary..until my computer freezes entirely and i reboot, but this time i cannot even get to the loading screen. What I am stumped on is that when i start up, my system recognizes both hard drives, yet never gets to any other screen after my POST screen. The overall problem right now, is that Windows (XP, SP2) does not boot whatsoever. I CAN access my BIOS, but right before the Windows loading screen I get random characters, along with absurd colors, flashing on my screen. This is scaring me at the moment, because this has never happened before and apparently no one else I could find had a similar problem. I have used my boot disk of XP to repair my main disk (my 500 gig WD drive) along with installing a fresh version on my previous drive i thought was corrupted (a 250 gig WD drive) I have also done a large list of things I could come up with out of my own knowledge along with the recommendations from other users on these boards/other forums including - -physically going inside my computer and checking connections of everything -running WD hard drive diagnostics -countless Windows system repairs with the boot disk -used BIOS availability to change power management, thinking something was wrong there...also changed BIOS back to defaults after all of this -changed my HDD access mode from Auto to Large (which had previously remedied my problem of not having my OS load, not sure if it ended up corrupting anything) - run all variants of CHKDSK on both drives, said that it "found and corrected errors" but it doesnt seem that way - also ran FIXBOOT and FIXMBR commands, to no avail at the moment I have gotten through the normal windows installation routine, but when my computer automatically restarts after the install/repair it goes back to the strange colors. what is going on, and what could the cause be? the only thing left that i think is the problem is that something with my partition was corrupted during the initial freeze. is there a way to find out/fix without doing another disk format? I have VERY valuable data on my drive that i need to back up. PLEASE any help would be appreciated. everything was fine until a couple nights ago and i just want everything back to normal :dead: Moderator Edit: I changed the title of your thread. Please use descriptive thread titles. Thank you.
