Frequently Asked Questions - Infinite 9SC-845MYS MSI
How do I install additional RAM on the MSI Infinite 9SC-845MYS?
To install additional RAM, power off the PC, unplug the power cord, and remove the side panel using the tool-less latch. Locate the DIMM slots on the motherboard. Align the notch on the new memory module with the slot, then firmly press down until it clicks. Ensure the new module is compatible with DDR4 and check supported speeds in the manual.
Can I upgrade the graphics card on this desktop?
Yes, the GPU is upgradable. Open the side panel, release the PCIe latch, and gently remove the existing card. Install a new card firmly into the PCIe x16 slot, connect the power cables if required, and secure it with the bracket. Make sure your power supply provides enough wattage and connectors.
How do I update the BIOS on the MSI Infinite 9SC-845MYS?
Visit the MSI support website, search for your model, and download the latest BIOS update. Extract the files to a USB flash drive, restart the PC, and press DEL to enter the BIOS. Use the M-Flash utility to select the downloaded file and follow the on-screen instructions. Do not interrupt the process to avoid bricking the system.
What should I do if the computer doesn't power on?
First, check that the power cord is securely connected to both the wall outlet and the back of the PC. Verify the power switch on the PSU is set to ON. Try a different outlet. If the issue persists, open the case and ensure all internal power cables are properly seated. If still no power, the PSU may need replacement.
How often should I clean the inside of my desktop?
It is recommended to clean dust filters every 2-4 weeks and perform a thorough internal cleaning every 3-6 months, depending on your environment. Use compressed air to blow out dust from fans and heatsinks. Avoid using vacuum cleaners which can create static damage.
Can I add extra storage drives?
Yes, the case has available bays for additional 2.5-inch or 3.5-inch drives. Connect SATA drives to the motherboard and power supply. For M.2 SSDs, locate the M.2 slot on the motherboard, insert the drive at an angle, and secure with a screw if present.
How do I reset the BIOS password if I forget it?
If you forget the BIOS password, you can clear it by opening the case and finding the CMOS battery on the motherboard. Remove it for about 30 seconds, then reinsert it. This resets BIOS settings to default, including the password. Alternatively, use the CLR_CMOS jumper if available.
Why is the computer making loud fan noise?
Loud fan noise can be due to dust accumulation, high ambient temperature, or heavy system load. Clean the fans and vents, ensure good airflow around the case, and check if fan curves are properly set in BIOS or MSI Dragon Center software.
How do I connect dual monitors to this desktop?
The graphics card has multiple display outputs (HDMI, DisplayPort). Connect each monitor to a port using compatible cables. For best results, use the Discrete GPU ports instead of the motherboard's integrated graphics. Windows will detect and allow configuration in Display Settings.
Is the MSI Infinite 9SC-845MYS suitable for VR gaming?
Yes, with its NVIDIA GeForce GTX 1660 Ti and Intel Core i7 processor, it meets the recommended requirements for most VR headsets. Ensure you have enough USB ports and HDMI output for your VR system.
