Im running windows 7 and whenever i put the computer to sleep and try to wake it I get blue screen of death or the computer would just restart. It sometimes would wake but would get BSOD after a couple of minutes. other times the computer wakes up but the screen stays black and i would have to reset.

Specs:
990fxa ud3 from gigabyte
antec 500w psu
FX8350 CPU
Asus r9 280x
4gb ram
250 gb hdd

Update chipset drivers. Also revert all overclock settings to default and check.

A Windows update was there too regarding the BSOD while waking up from sleep on certain HDDs. So check that as well.
 
S3 sleep problems are almost always RAM related - the stuff in ram gets corrupted while its sleeping, so that when it wakes up it crashes.


can sometimes be caused by a PSU with bad voltages when at low amperages, but almost always bad RAM or bad RAM settings (voltages, MHz, northbridge/IMC settings, etc). manually set it all to where it should be, and if it still crashes try lower settings.
 
go and set your bios to defualt
 
It could also be a bad/unsupported driver install and/or hardware (w/o the driver).
I had that with a TV tuner card, where the system would enter sleep (S3/S4) but wouldn't resume. Everything turned on, but the screen would stay in power-saving mode. It wouldn't change from that state unless I resorted to rebooting.
The event manager was clueless about this, btw.

could it be because I'm running 1 4gb ram module instead of 2 2gb modules?

no, in theory that should be more stable. you just have to manually set the RAM's settings in your BIOS. RAM settings are *NOT* loaded automatically, they just use a generic profile that 'should' work with all memory, but you're still meant to set it up yourself in the BIOS.

What settings should I change?

frequency, timings, voltages. to whatever your ram says its needs (usually on the label)
 
My computer can go into hibernation with no problems but when I put it in sleep or hybrid sleep it fails. So it must be the ram and not my processor or HDD?
 
i think i have heard of these problems with latest amd drivers. try different drivers. hope you arent using beta drivers

it could be the proccesor because thats where the memory controller is on modern systems, but its definitely related to the RAM. have you set your BIOS settings correctly yet?
 
is everything you are using hybrid sleep compatible? like the software?

I cant find the settings for my patriot psd34g16002 ram anywhere.

its probably written on the side on the sticker. post up a photo and i'll see what i can find.


edit: looks like 1600Mhz CL11-11-11-27 1.5v


so google up how to manually set your ram timings and it'll tell you the name for each of those numbers, and where to put them in your BIOS. personally i'd suggest 1.55v for the ram as well, it may need a little extra juice if somethng in your system isnt quite working perfectly (voltages a little low from PSU, etc)

it says cl 11 on the sticker

yes
the numbers i gave you above are the rest of them, i googled the number you gave me and found it. now you need to enter them into your bios.

I tried 11-11-11-27 and it didnt work and it was set to 11-11-11-28 by default

ok well thats a good start, what voltage is it set to? if its 1.5v, try setting 1.55v or 1.6v (dont go above 1.65v)
 
In my old I7-920 I could never get sleep to work. One time I had to removed the ram and clear the cmos before I could get it to boot after letting it sleep. I now use hibernate on my laptop for work and its been pretty reliable.
