Is it possible? Only errors in memtest.

Hi,
I decided to Memtest86+ v4.10 on my netbook and it shows only errors. I am on 60% testing atm, nothing is passed and i have more than 700 errors.

The computer seems to run fine on Xubuntu.

Could it be a virus? I was reading at a post here that some viruses stay on hard disk when hibernate/shutdown and go to ram when the OS is started. And i have a bad sector on the disk.

Could it be the BIOS settings? It has some settings i did not understood and left them in their default settings.
 
Either your machine don't like that version of memtest, or you have RAM errors.

Highly doubt this has anything to do with a virus.
 
^You mean a different test number on the same version of memtest? If so you still have bad memory. Tests 5 and 8 are the most commonly failed tests, while all the others can pass fine. I've had bad memory fail test 6 before I believe too.
 
The first one was from Ubuntu 10.10 Live. It was the standard test. I did not bother with the extended test since it completely failed. Maybe it was some kind of incompatibility.

The second test was from an old floppy (computer check only floppy) i found in a computer shop some years ago.
I run the standard and the extended memory test it has. And it passed.
 
why not download memtest86 run it for a few hours.. not just 1 pass. Ive seen computers run fine for months that fail ramtest..not like you use all your ram
 
If the info is correct in your sig about your notebook, then you have 2 sticks of Ram. (1) 256MB and (1) 128MB, most likely different timings and voltages too. Remove the lower of the 2 and do the test individually. There isn't much Ram there to test.

I have has 16 gigs run in my system for days then it would BSOD. Did a test and found that 1 stick, running memtest, Failed. You on the other hand, have a PIII system running what OS? And with 384MB of SD Ram, Memtest will pick it pretty quick.

If all the RAM was bad, MemTest86+ wouldn't run.

You can eliminate the hard drive as a problem source by disconnecting it during testing, and perhaps doing so through the BIOS setup may be sufficient. However I seriously doubt you have a virus problem, and I would try other BIOS settings but doubt they'll help.

What does MemTest86+ do with only one DIMM installed at a time?

What brands of memory chips (not DIMMs) are you using?
 
I had run Memtest86+ v4.00 from OpenDiagnostics LiveCD and had no problems with 2 passes. Maybe the v4.01 is not suitable for SDRAM testing. The test was done with all the memory.

I saw a 256MB SDRAM stick, and from a service manual i found about the netbook, it seems the other 128RAM is printed on board. I did not check that as it requires taking apart most of the netbook.

The netbook was given to me from my brother, and has suffered a heat problem since the first month he bought it (the bottom air inlet ducts were closed and it overheated). I did no upgrades of any kind apart from getting a small flexible keyboard for it. It has a bad sector and a dead battery but otherwise works well. I will leave it running an OS for a week to be sure.

In the BIOS i set the GPU shared memory to 32MB. Memtest shows 352MB of memory, and the adding makes 384MB. I guess this is normal.
