Run an OCCT / FURMark test and check the temps (Might be good to clean out CPU and GPU fans and heatsinks)
I'd inspect your motherboard for any burst or bulging capacitors
Then unplug and replug everything (PSU power, wall plug, 24 pin, 8 pin, GPU, RAM, HDD power, SATA, etc.)
Run a memtest 86+ for RAM and a SMART diagnostic for your HDD
Work from there as your PSU should be MORE than capable.
Hi, these are the things I've done to check the system so far:
- Ran Furmark with both my 560 and my old 9800: 560 freezes almost immediately, in fact yesterday it froze just by having it connected to the system and launching it. Max temp during this was 50°C. 9800 freezes about 75% done, max temp 71°C. I checked using GPU-Z (today)
- Changed Nvidia drivers, even going to old releases (yesterday)
- Tried connecting the card using only
Molex to 6-pin adapters to see if it maybe was a cable problem, but it didn't make a difference.
- Tried different sata connectors for the drives and changing to the other 12v 4-pin connector for the Mobo.
- Tried disabling Nvidia HD Audio drivers (the ones that control audio coming out from the card) as I read they could conflict with the Realtek drivers and cause hang-ups and freezes (yesterday)
- Everything is super clean. When I put the system back together about a month ago I took my case apart and cleaned it, including the GPU and PSU that I was reusing. I think I was very thorough with this. (I checked today again, I have the GPU out so I can see clearly and no more dust comes out from it).
- I ran Real Temp today
(LINK) and as you can see the highest the CPU ever got at 100% load was 60°C. It completed the test without a problem. I also ran memtest 86+ for the better part of today (1 got 2x4GB) 1 stick at a time, 2 passes each and it didn't present any errors. Should I let this go on for longer?
- I did try the quick Check for System Errors in the win 7 computer management tools, but 'll look for something more thorough. I have 3 HDDs connected right now, 1 SSD (new) and 2xWD 500GB. Launching with just the SSD connected in and the system is still unstable (today)
- I've had the computer running today (aside from the testing) with integrated graphics and it seems fine. I'll try running FURmark with the IG I guess.
I'll also try disconnecting everything again, and taking out the motherboard to check for bulging or burst caps (i didn't catch any at a glance) and try to connect everything back in. I'll download OCCT but I don't know if I'll get that far into testing, and I'm afraid it might screw the PSU for good and I don't have a replacement here yet. I ordered the CX600M already.
I asked because I'm really out of ideas, as I've been checking all that stuff and it basically comes down to this: It started with the system freezing when under heavy load (mainly games, no BSOD), but now it freezes with just having the 560ti in. With the 9800 GT in I can launch some stuff, but after a while it freezes too. now I'm running it with only IG and it seems OK with non-intensive stuff. I tried launching Diablo 3 and fooling around for 20 mins and it didn't crash.
I've had some video cards go bad before so in my experience those issues manifest differently, so the only thing I can think of is the PSU is no longer up to task (it's been working for 5 years now after all). The thing that bugs me is that my new processor i5-3330 should draw less power than the one I had before, a Core2Quad, and everything else is relatively the same and had been running fine for a month.
Thanks for your input and I welcome any more opinions or ideas on this if anyone has any, I know it's probably asking too much to read these walls. (
