I have a computer that's having trouble starting up properly and was wondering if anyone here can help me out. The specs are an Athlon 64 2800+ socket 754 cpu, a Chaintech Nforce3 250 "VNF3-250" motherboard, and a gig of Corsair PC3200 Value Ram. Now I know it's not the memory that is causing the constant reboots because I swapped it out for another pair last night. I've also scanned the hard drive for errors and it has not found any. Anyways, whenever I boot the computer up, it scans the hardware normally and I"m able to get into the bios but when it starts to load windows, it gives me options to either start up in safe mode or start windows normally. After I choose either, it starts to try and load XP but then reboots itself. Before this started to happen, the HD led would blink and I would hear a constant beeping sound. I would then reset the cmos and it would start XP normally but after awhile and at random times, it would either freeze up on me or I would get Memory dumps or Kernal_stack_Inpage_error blue screens. I've already reformatted twice so it's not the software. Could it be the cpu? Motherboard? hard drive? Thanks for any possible help.
