OK, this is starting to get too weird. Starting from today's issue, the reception computer just went to a BSOD. I have all of the error messages written down, most of them addresses or grops of numbers. I just rebooted, and it booted to CHKDSK, which showed no hard drive errors.
I then ran Memtest, and it was fine for around three minutes, then immediately starting finding errors at such a rate that if I ran it for hours, I am sure it would have gotten into the hundreds of thousands of errors. As it was, since we needed to get back to work, I stopped it, and the computer immediately booted into Windows.
I have attached a print screen of four windows of CPU-Z. The reason this is weird is because, I have a network of a server with 7 computers for three years, and I have had no issues. Now, I have had three computers show a BSOD. Two for RAM issues and one for a failing hard drive. The first one was a failing hard drive on the triage computer. After troubleshooting it extensively, CHKDSK showed multiple errors in multiple sectors. Changing the hard drive seemed to fix that issue. I then got a series of error messages running on the black screen in BIOS on the room 1 computer. This revealed eight errors in Memtest86. Crucial had recommended Ballistix memory modules which were supposedly compatible with the motherboard, but Gary C. thought otherwise. Removing one stick (either one) allowed the computer to run. I ordered two new RAM sticks from Kingston, and installed them yesterday, and there have been no problems.
Now today, I get the error mentioned above which showed more than 7500 errors which I stopped. I haven't had an error since then. I am rather certain this computer has the same RAM modules that were on room 1.
I guess I am not sure why RAM that is not compatible due to voltage would work for six months and then start having issues the same week.
One thing that may be important to note is that the reception computer which is having the problem had a trojan on it about three weeks ago. This was removed with MBAM and ComboFix indicated everything was fine. I doubt it could have done any of this. And, I checked every computer with MBAM and SuperAnti-Spyware. Plus ESET is always running.
So, in summary, within the last three weeks:
Reception PC: Trojan -- successfully removed with MBAM
Triage PC: BSOD -- hard drive failure fixed with a new hard drive
Room 1 PC: Error showing black screen with statement that BIOS was not working and a continuous cycle of Can't Find CD-ROM, Can't Find Floppy, Can't Find CD-ROM, over and over, etc. This was fixed with two new 1GB sticks of RAM after memtest86 showed errors in RAM
Reception PC: BSOD -- memtest86 shows greater than 7500 error messages. Running OK with the same setup, but obviously, it is going to crash again.
So, should I just replace this RAM also? Do you think any or all of these events are linked? Given I do not know anything about testing RAM, are 7500 error messages worse than 8?
