Here are the current specs to put things in context:
- ECS P4VXASD2+ V5.0
- Intel Pentium 4 Northwood 2.8 GHz
- 2x 512MB PC2100 DDR266 SDRAM
- Maxtor DiamondMax 10 250 GB PATA (IDE) HDD
- Gigabyte 52x CD-ROM
- NVIDIA TNT2 Pro 16 MB
- OKIA 300W ATX PSU
- USB bracket
- Modem PCI
Before, I actually had a 300 GB hard drive installed. However, I read the FAQ for the motherboard and discovered that a maximum of 250 GB hard drive was supported. So I ended up finding the one listed above and put that in.
However, upon booting up, I reset the BIOS to defaults and auto-detected all the drives installed. The 250 GB came up as something like 251.0 GB. I didn't think much about it until I tried to boot up a Windows XP installation disc. It booted up successfully and run for about a minute before the computer randomly rebooted.
I've made sure that all the jumpers and settings are correct and everything has been installed correctly. I've tried running it without the addons and one stick of RAM but still the same thing.
What else could be causing this problem?
