Frequently Asked Questions - Compaq Presario SR1800 HP
How do I reset my HP Compaq Presario SR1800 to factory settings?
To reset to factory settings, restart the computer and press F11 repeatedly during startup to enter the recovery partition. Follow the on-screen instructions to restore the system to its original state. This will erase all data, so back up important files first.

Can I upgrade the graphics card in the SR1800?
Yes, the SR1800 has a PCI Express x16 slot for a dedicated graphics card. Ensure the card fits in the case and does not exceed the power supply's capacity (300W). A low-profile card may be needed for smaller cases.
Why is my computer not turning on?
Check the power cord connection and try a different outlet. Ensure the power supply switch (if present) is set to ON. Listen for fan noise; if none, the power supply or motherboard may be faulty. Try removing all peripherals and booting with only essential components.

What is the maximum hard drive size supported?
The system supports SATA hard drives up to 2 TB, but the motherboard may limit to 1 TB without a BIOS update. An IDE drive can also be used as a secondary drive.
How can I clean the inside of my desktop?
Unplug the computer, open the side panel, and use compressed air to blow out dust from fans, heatsinks, and components. Avoid touching internal parts. Hold fans to prevent spinning during cleaning.

Most models do not include built-in Wi-Fi. You can add a USB Wi-Fi adapter or install a PCI or PCI Express wireless card.
