I need help sorting out this issue

My PC will just randomly put itself to sleep and when I get it to resume there is a whole pile of gobbledygook in the sticky note application (or word if I have that open when it happens). I initially thought it was a temperature problem, but I am now running gpu-temp and real temp to monitor temps of both my graphics card and cpu and none of them ever peak above 55 Celsius. It also makes either 2 or 3 very short beeping noises through my headphones when it does this. I don't know if this is related but when working in adobe Photoshop or illustrator my screen will temporarily lose signal and I will get a report that My graphics card driver has crashed.

This is all very recent and I have not made any software or hardware changes in the past 3 months or so. I would prefer not to go through the pain of having to re-install windows.

My PC specs are:

i5 760 (stock cooler, not overclocked)
generic 4gb ram
gigabyte gtx 460 se
thermaltake toughpower 575W PSU
seagate 7200.12 250gb HDD

I also have 2 1TB external hard drives that are always connected as well as a usb dac connected to a tube amp and my headphones
 
Hi Alfroogy,

Try to update your graphics driver. I had the gfx issue a while back and that sorted it out. Have you opened the case and check that the dust is not clogging your heat sink?

I have the latest non beta driver, have recently cleaned out the whole case with compressed air
 
Hi There,
have you tried another graphics card in case that is faulty?
Your issue with it happening with photoshop may indicate that to be the problem.

Regards

Tim
 
before cleaning... cleaning was done because I initially thought it was a heat problem... just remounted everything and checked all cables etc now as well and still happening, I do not have another card to try it with, but after doing some research it looks like a faulty card

this sounds very similar if not exactly like my problem. I think I will just try RMA it as I believe it is still under warranty
 
Are you running windows 7? if so just go into windows 7 power options and turn off the sleep mode.And under power options just set your power option to high Performance.
I had the same probs before this fixed it for me.

^ Was just about to suggest this.
 
Narcolepsy has several causes. Perhaps try to get enough rest during the night, so make sure to switch off the pc when you go to bed.
 
disabled sleep, so its not that I use avast and nothing comes up, getting a mates graphics card today to test it out. I have a strong suspician from the research I've done on the net that it may be a faulty graphics card apparently gigabyte gtx 460s are notorious for it.
 
Hi there!

The next time it goes to sleep, open the event viewer from the control panel, then on the left hand side, expand "windows logs" then click "system" and look for the event where it went to sleep. The source for the event should be "kernal power". Click on the event and the reason it went to sleep should hopefully be displayed
