I'm going to try and describe everything in detail, sorry for making it so long but I feel the information is necessary.
So about 1 year and a half ago I bought myself a PC. After a year with it I wanted to install a GPU but it wouldn't fit inside the case. I decided I would just build my own gaming PC from scratch since I had some extra money.
I bought a new motherboard,RAM, and case at Fry's. I wanted to get a new processor and hard drive but didn't have enough money for everything, I just added the one I had to my build, same thing with the hard drive and made sure all my hardware was compatible before I bought anything.
After hooking everything up I tried to turn it on but it would turn on for a second and shutdown in a cycle. At first I thought I didn't install something properly but after some research I found out that it could be my RAM causing the problem. Turned out one RAM stick was faulty and everything was working properly after i removed it. 2 weeks later without any problems on my PC, I returned both RAM sticks for 2 new one's because I was only running on one 4GB RAM. Everything ran good for a couple of weeks until I got a BSOD. The BSOD wouldn't happen constantly just randomly every couple of weeks or longer periods of time.
2 days ago it BSOD'd again after about a month or longer of working properly. I tried running AVG to scan for viruses but it wouldn't scan, I noticed that windows didn't recognize it as my anti-virus program either. I installed malwarebytes and it found multiple problems, which I removed. After removing the files my PC started getting BSOD constantly. Some of the files removed were registry files for windows. I couldn't run a full scan of my system after, once it reached 30% it would BSOD. I went into safe mode, was able to run AVG and it found 17 viruses but BSOD'd before it could finish. I decided to just wipe the hard drive and reinstall windows since most of my files are on my external hard drive. I wiped it through command prompt DISKPART. While installing windows it would give me an error at 10% of installation. I removed one RAM and got to 30% before failing, I put the one I took out in by itself and windows was finally able to install.
After reinstalling windows I tried running with both RAM's installed again but would BSOD. When I remove one everything works fine with no BSOD, if I put the one I took out in by itself my PC restarts during startup or just BSOD. I put the one that works back in and my PC did a disk check before I could log back in but no problems ever since.
I am glad i can use my PC but not being able to use 8GB's of RAM is a real pain since I built this PC for gaming.
So I wonder could the virus have messed up my RAM or is it possible that one became faulty after a while? Could my motherboard be the cause of the RAM becoming faulty? Could the virus still be on my hard drive causing this to happen or have infected my motherboard or RAM?
I am thinking about exchanging the RAM and motherboard for new ones since i have warranty, wait until I can buy a new hard drive, processor, maybe OS too and then build that to be safe.
I just wanted to see what you guys think first since this forum has helped me before. I appreciate anyone who took the time to read all of this, I will provide my specs below.
could you try to test the ram with memtest at least 5 times and if the pass i would look for a rma on the motherboard .
I let the RAM that works test for one pass and no errors.
When I started the test for the 2nd RAM I instantly got 65535+ during test 1 and so on. I let it run for 2 passes and the errors stayed the same with Max Contiguous Errors: 74
