Strange OS behaviour on boot - SSD stops responding

[Tomate]

Hi everyone, and thanks in advance.

 

I had my machine running on an old case, it had been running for about two years without any problems. I bought a new case, so i took the system down, dissasembled it completely, dusted it off a little (with compressed air cans and such) and re-built it into the new case.

 

Now i'm having this strange problem, where one every two boots gets into windows normally, but after a few minutes of functioning, Windows seems to stop responding (for example, i can't CTRL+ALT+DEL, or access any windows dialogues). I've noticed that every application that is installed on my SSD (boot drive) also stops responding. (For example, if i go into my music library, which is in my secondary optical drive, everything works fine, but if i try to access anything on the SSD, explorer stops responding).

 

Also, when i leave the computer off overnight, as i turn it on in the morning, it'll boot up to the "ASUS!" splash screen, and then stop outputting video signal to my monitor? This is extremely strange, and is fixed by hitting the reset button.

 

I don't think it's a MOBO problem, BIOS is all good.

 

System:
Asus P9X79 pro motherboard.

i7-3820, was overclocked, but i took it down to stock during troubleshooting, so 3,60 Ghz.

GTX 650ti - Zotac AMP! edition.

Samsung 840 EVO SSD (as a boot drive, OS and a few select apps on it)

TOSHIBA 1 terabyte optical drive. (Which seems to have no problems at all)

Thermaltake 500w PSU (80+ bronze certified)

 

Thanks in advance, everyone.

 

So far, i've tried checking the SSD with Samsung's magician tool, and everything seems okay. I also tried changing the SATA ports on both drives (?), even trying the same configuration i had before the case swap, and still nothing.

 

EDIT: In case it matters, i did remove the CPU cooler to replace thermal compound, it's working fine and it's got OK temps though. I also did an error check on the storage drives, nothing.

Did you clean install windows to your SSD?

I didn't change a thing, i just swapped all the components into a new case, so it's the same, functioning copy of Windows 7 64-bit, it's just acting up now

check all your drivers are up to date

windows, GPU, etc...

Did that upon re-assembly (sorry to have missed it in the main post). The only driver out of date was my GPU, updated it, but problem's still going.

do a disk check with windows

you might need to reinstall windows to fix this issue

I did disk checks and nothing came up

Yeah, a clean install is what i'm trying to avoid.. Is there any chance it's anything else? (I know that's a pretty dumb question in troubleshooting.)

I cant think of anything else that would cause that...

 I just performed a full, clean install of the OS.. And the problem is still here :'(
