Question:

“I’ve encountered a power issue with my PC. During transportation, the graphics card was accidentally dislodged but has since been reseated. Following this incident, the PC ceased all functions, although the keyboard indicates that power is still being supplied. I’ve attempted a CMOS reset as suggested, but to no avail. Could you provide any expert advice on how to resolve this?”

Answer:

When a PC stops functioning after a graphics card has been dislodged and reseated, it’s crucial to approach the problem methodically. The fact that the keyboard still lights up is a good sign; it means the motherboard is receiving power. However, the lack of other functions suggests that the system is not completing its Power-On Self-Test (POST), which is essential for booting.

Firstly, ensure that the graphics card is properly seated in the PCI-Express slot. Also, check all other connections within the PC, including power cables, RAM, and data cables, to ensure they are secure.

Step 2: Check for Visible Damage

Examine the graphics card and motherboard for any visible signs of damage, such as bent pins or burnt components. If any damage is found, the affected component may need to be replaced.

Step 3: Test with Minimal Configuration

Strip down the PC to its essential components: one stick of RAM, the CPU, and onboard graphics (if available). Remove the graphics card and any other peripherals. This can help isolate the issue.

Step 4: Clear the CMOS

Since the initial CMOS reset didn’t resolve the issue, try clearing the CMOS again by removing the battery for a few minutes, then replacing it. This will reset the BIOS to its default settings.

Step 5: Listen for Beep Codes

When powering on the PC, listen for beep codes. These codes can indicate what kind of hardware issue the PC is experiencing. Refer to the motherboard’s manual for the meaning of the codes.

Step 6: Try a Different Power Supply

A faulty power supply can cause power issues even if some components are receiving power. If possible, test with a different power supply.

Step 7: Consult with a Professional

If the above steps do not resolve the issue, it may be time to consult with a professional technician. They can perform more advanced diagnostics and potentially repair any damaged components.

Remember, dealing with internal PC components can carry risks, such as static discharge. Always take appropriate precautions, such as using an anti-static wrist strap or working on a non-conductive surface.

By following these steps, you can systematically troubleshoot the power issue and hopefully restore full functionality to your PC. If you’re uncomfortable performing any of these steps, it’s best to seek professional assistance.
