The motherboard works fine without it, so no need to replace that. If the system boots with some modules but not others, you've likely found a faulty RAM stickHow to fix Hp laptop blank screen issue?

Step 4: Check RAM Slot Configuration

* Consult Manual: If your HP 7900 has multiple RAM slots (eHow to fix Hp laptop blank screen issue?g2023911—It seems clear that the 8thRAMis bad and needs to be replaced. The motherboard works fine without it, so no need to replace that., a total of 4 slots and you're trying to use 2 of them), consult your HP dc7900 owner's manual or the HP support website to determine the correct slots to use for optimal performance and compatibility, especially for dual-channel modeRemove battery, disconnect power adapter,then press and hold power button 15-20secs, after all that, reconnect power and retry to boot  For instance, if you have 2 slots occupied, using slots A1 and B1 (or their equivalent labeling) might be necessaryASUS ROG Strix X670E-E Gaming WiFi features 18+2power stages, DDR5 support, four M.2 slotswith heatsinks, PCIe® 5.0, USB 3.2 Gen 2x2 front-panel connector  Incorrect configuration can lead to one or more slots not being recognizedHalf of my RAM is hardware reserved?

When is it Time for a Professional Opinion?

If you've gone through these steps and the 2 ram slots on your HP 7900 remain non-functional, it's highly probable that there is a hardware defect with the motherboard itselfDesktop computers and All-in-One PCs Repairing motherboard components like RAM slots is complex and often uneconomical for older systems like the dc7900when using only 2 out of 4 ram slots which 2 are best? In such cases, your best options might include:

* Using the Functional Slots: If at least two RAM slots are working, you can continue using the system by installing your RAM in those functional slots2024615—You need to use2& 4 (Preferred) or 1 & 3 otherwise it will only operate in Single-Channel mode instead of Dual-Channel and it'll perform worse.

* Motherboard Replacement: If you’re comfortable and capable, replacing the motherboard is an option, though for an HP 7900, this might not be cost-effective compared to upgrading to a newer systemASUS ROG Strix X670E-E Gaming WiFi features 18+2power stages, DDR5 support, four M.2 slotswith heatsinks, PCIe® 5.0, USB 3.2 Gen 2x2 front-panel connector 

* System Upgrade: For many users, especially if facing persistent hardware issues, upgrading to a newer HP desktop or all-in-one PC might be the most practical solutionDesktop computers and All-in-One PCs
