computer will turn on and off when i turn it on need help

[russianguy]

Ok so my computer was using 2 rams and after some time i update my motherboard bios or something like that and later some days it started to work weird like i turned it off and the next day it would just turn on and off after i took one of the rams out it worked fine and it might be from avast to because i did a virus scan before the ram problems and i had 2 blue screens of death so what is the issue with my ram or the motherboard.
plus i use to run 4 rams but it would keep restarting my computer after like 1-2 hours of using it so i went back to 2 and now i have another problem i have alot of bad luck with computers  so please help me because i am taking it to a person to check it out tomorrow if you could please give me some advice on how to fix these plz help.

Is that RAM on iNtel's Supported Vendoe List for that MBoard ? ?
<akes a difference with the higher speed DDR3 RAM....

[russianguy]

yea the ram sticks support it

[patio]

It's the other way around...the MBoard needs to support the RAM....did you look it up in the manual ? ?

[russianguy]

yup it supports it

[patio]

Try every other RAM slot...

Comrade,
               Did your computer started giving  you problem only after you updated your BIOS.Or did the Problem exist from the beginning.

[russianguy]

i think it was after the bios update

[patio]

At 3 months old it should still be under warranty.....i'd be taking advantage of that.
Not sure why a BIOS flash on a brand new machine...

[russianguy]

ok

[tobydorji]

You have the solution.After the update the problem arose.

Go and make use of that warranty period. But make sure you dont mention about the Bios Update.
