I know this is a verry reduntant but Ive looked through many threads and google trying to find any related problem but none seem to have the same problem I have.

So my after my desktop is in sleep/hibernation it would randomly, after some time (I dont know if its everytime) turns on (led lights,fan, motherboard sound) but no monitor picture, then turns off after a few secs.

Ive checkedpowerplan, everything and theyre all disabled including the lansettings in bios.

I also noticed lately my computer has been getting laggy esp with ie, youtube and LoL.

I dont know if these two are related, but I would like to know any more options as to how/why my computer turns on byitself before i come to the conclusion that it could potentially be some virus.

but it shuts off immediately a few secs after, computer doesnt boot,like I said just led lights, fans, sounds etc. turn than turn off. it can update in this state within a few secs? and I mean as in 2-3 seconds.

It could be checking to see if there are updates to download that would probably only take a few seconds or it could be a piece of software like anti virus doing something. But it couldn't hurt to do a virus scan (i would think it would be something serious if it managed to turn your computer on) i would suggest malwarebytes for the scan.

I had done a virusscan,malwarescan, i think ive tried 5-6 different softwares Initially I had some, got rid of them ,scanned again multiple times again with different softwares and it shows its clean now. but maybe i didnt...

I forgot to mention though, alittle after when i had intially built my computer, again randomly, my computer would turn on itself when it was completely shutdown, but would stay on. It had done this several times in the middle of the night, so I had to wake up turn it off. I thought it was a ghost initally =[ I dont know what I did to fix it but this doesnt happen anymore.

Computers are weird when i first built mine every time i turned it on it would do nothing until i hit the restart button then it would boot up fine. Then one day about a month later it fixed itself and never did it again to this day about a year later it has not done it again so who knows if it doesn't do it again i wouldn't worry about it.

Okai, so I can officially say now that my computer turned itself on after a COMPLETE SHUT DOWN. It wasnt on hiberernate or sleep this time It was shut off and maybe a minute later it booted itself. i got so scared =[ Does this smell like a virus?
