Guide. An iron test checks the amount of iron in the blood to see how well iron is metabolized in the body. Iron (Fe) is a mineral needed for hemoglobin, the protein in red blood cells that carries oxygen. Iron is also needed for energy, good muscle and organ function.
The following errors are the most common symptoms of faulty (or failing) computer memory modules: 1  Computer memory errors. 2  These include system computer memory errors, or blue screen system crashes that reference memory read/write, parity, interrupt, address, page faults, general protection faults or mismatch errors.
It's rare but RAM modules can cause problems. Unfortunately, it's not always certain that the memory errors being reported by your system is actually due to problems with the RAM modules. Even worse is that an unstable system can be due to many problems including RAM failure.f it's hardware then you are probably going to have to open the computer case (steps 5 - 10 & 13). You may prefer to eliminate other problems first (steps 11-12). Or even run diagnostic software (step 14). Step 4: Gather all the documentation that came with your computer, memory modules or MOBO (motherboard).
