HP computer freezes at BIOS splash screen

General Info:
- Computer: HP a530n
- Upgrades: None
- Age: 4-5 years old

Every time I turn on the computer, it freezes at the BIOS splash screen. I've tried resetting the CMOS, replacing the RAM, and replacing the hard drive. Sadly, none of these changes have alleviated the issue. Any help in fixing this problem would be greatly appreciated.

How much are you willing to spend to fix it? It probably is the motherboard, but you'll have to buy a replacement to find out for sure. Is it worth it?
