Attempted RAM Upgrade - CPU Usage spikes to 100% - Now Sluggish
Hi all, I could really use an assist as I am on a tight deadline and suddenly my CPU isn't working as it should.
I just attempted to add 8 GB of DDR4 Ram to my new Dell Precision Workstation Tower 5810, to bring my total installed to 16GB. So I got two 4 GB Crucial sticks from Amazon, and was careful to match the specs with the factory installed RAM: RDIMM, ECC, 2133 MhZ, DDR4.
So I added the two sticks to DIMM slots 3 and 4, and on boot, the computer wouldn't even enter the BIOS. It gave an error code (flashing lights on the power button). So I removed the 2 new Ram sticks, basically restoring it to the previous state.
On re-boot, I notice that my CPU Usage now spikes and sits there at 100% whenever I launch a program. Chrome, for instance, is incredibly sluggish. When no program is launched, CPU Usage sits at 0%.
I ran a full MBAM scan, no viruses.
Also ran CCleaner, nothing strange there.
I ran a performance benchmark in Samsung Disk Magician software, to examine the state of my OS drive (256 GB Samsung 850 Pro SSD). It now benchmarks at 1/10 the speed it did before. Very bad.
I also saw a BSOD on one bootup - a driver IRQ failure on iastora.sys, which I believe is the factory installed Intel Rapid Storage software. I installed the latest driver from Dell, but the problem persists.
I am working in Adobe Premiere Pro and need the machine to be a speed demon, so now I can't really work on this machine in its current state.
Can anyone help me figure this out? I really need the computer to get back up and running.
