Thank you for sharing this helpful discussion. Here’s a concise summary of what you could achieve with your $250 budget:
- **Processor upgrade:** Switched from Intel Core i5 to Core i7-3632QM (both low power), saving around $90.
- **Thermal paste:** Purchased Noctua NT-H1 3.5g thermal paste for about $17.
- **RAM boost:** Upgraded from 4GB to 16GB Corsair memory, which improved performance noticeably.
- **Storage:** Acquired a Samsung EVO 860 500 GB SSD for $65 (after discount).
- **Wi-Fi card:** Installed Intel Duo Wireless AC 7260 for $30, though delivery was pending.
- **Boot troubleshooting:** Reset BIOS by removing CMOS battery briefly to resolve boot issues.

Some challenges included:
- A CPU fan replacement caused random restarts.
