PC resetting when left unattended.

[SOLVED] PC resetting when left unattended.

Hey guys,

The pc showing in my 'spec' profile is a new build, its been running great for about a week.

I opened it up to drop in another 4 Gig of RAM and a Light (tiny little blue tube thing, just to give it a nice glow) and as far as i knew all was great.

It was on last night, when i got up this morning all was still great. then at some point this after noon it had reset and stuck in the 'loading OS' screen saying BOOT (something) not found'

I immediately turned off the PC, opened it up and checked all was well, it was, so, i turned it back on. all was fine (apart from the usual 'windows did not shut-down correctly screen)

EDIT: so far its not done this while ive been sitting using it

then later today i was streaming a TV show over to my playstation (PS3 media server) and about 20 mins in poof, the PC was resetting.

It did it twice more.

I have since removed the extra RAM I added and with or without it i am still having this strange issue.

as it the only clue i had was the hard drive i have turned off the option to 'put hard drive to sleep after X mins' in POWER options.

any advice would be great.

EDIT: turns out by disabling my PC lights the problem went away - thank you for help

Update:

I have just updated my BIOS and disabled that pesky little light. I'm hoping that this fixes the problem or at the very least its something off the check list.

If the BIOS update doesn't fix it:

Sometimes adding more RAM does require a manual adjustment in BIOS to up the voltage a bit.

I would run a memory test - Windows memory test and/or memtest86.

Also, re-seat your current installed RAM, it may have been "touched" when you added the extra 4 GIG.

I'd also go into BIOS and make sure everything looks OK.
By adding and removing the new RAM, the BIOS may have made some "Auto-Adjust" change...

thanks for pointers

I have now checked the RAM its all seated great, really snug.

So far this evening the PC has not been naughty but I've been sat here playing SWTOR (temperatures fine and using about 5gig of RAM at the moment)

im hoping the BIOS update/turning off the light has fixed it but ill let you know if its still on in the morning.
