Can't load Windows at startup (harddrive problems??) First, let me start by posting my computer hardware: Processor: AMD Athlon 64 X2 4600+ @ 2.4GHz 2 x 512KB L2 Cache Socket AM2 Dual Core Processor RAM: 3GB 240-Pin DDR2 SDRAM 800 (PC2 6400) Graphics Card: eVGA Geforce 7900GT 256MB 256-bit GDDR3 PCI Express x16 Hard Drives: 300 GB SATA CD/DVD Drives: DVD+R/RW 4x DVD+R/RW 16x OS: Windows XP Pro SP2 I have been messing around with overclocking (RAM, CPU, and GPU) and my computer would randomly restart and I never saw a blue screen. Now my computer will not load Windows, period. The moment it starts to load up I see a bluescreen flash very fast and then my computer restarts and after this started happening I restored all the defaults in my BIOS. This did not resolve the problem so I decided to try to reinstall Windows XP with the install CD. When I chose to install Windows or use the Recovery Console after about 30 seconds when it [probably] is done scanning my hardware configuration I see a blue screen and my computer doesn't restart. This blue screen says something like "ntsc.sys time stamp: xxxxxx" and never terminates until I force-shutdown my computer. So, my overview is: my computer gets a blue screen for a frame and then restarts as soon as Windows starts loading and I have my BIOS on its defaults. Loading the Windows installer from the Windows CD gives me a blue screen as well. I was overclocking but having the BIOS on its defaults means it isn't overclocked anymore. Help appreciated. Major edit: I haven't been able to boot up Windows or do anything with the Windows instal CD. Because of this I tried testing my RAM with the bootable MemTest and that yielded no errors. I also tried booting with one piece of RAM that passed the test 4 times, still the same problem. (This part is the most important now) Just recently I took my [only] harddrive out and hooked it up to a different computer. If it is connected when the computer boots up the computer reboots just before finishing booting up, so I waited to plug in the SATA cable until after Windows was done booting up. From there I clicked "Add new hardware" from the control panel. About 2 seconds after the balloon in the bottom right said "Found new hardware: SATA ST3300620AS," the computer rebooted right away. From this I know that the problem lies with my harddrive but I do not why or how to fix it. I think that the harddrive is still under warrenty but I am most certainly not willing to give it up for I have about 200 GB worth of highly important data on the harddrive. What do I do now?
