System instability!

[taowu]

Hi guys,

I've been having some issues with my system locking up and sometimes blue screening.

The issue has mainly popped up since I have moved over to my new ATI Powercolour PCS+ 5850.

I had the odd issue before of a system lock up and my display drivers crashing with my Nvidia 8800GT, yet at the moment it happens a lot more than before.

My system is:
ASUS P5N-D nForce 750i mobo
Intel Core 2 Dou E8200
OCZ 2GB(2x1GB) DDR2 800MHz Platinum XTC
Maxtor 160GB (MAXTOR S TM3160811AS)
Maxtor 200GB (MAXTOR 6 B200M0)
Samsung 500GB (SAMSUNG HD502HJ)
ATI PowerColour PCS+ 5850 1GB
2x DVD Drives
5x 120mm system fans
Hiper 530W Black Type M PSU

I have been wondering if this could be a power issue, since it has blue screen when I have been playing something like Modern Warfare 2 or Crysis.

Also I have ATI Tray Tools installed, I was wondering if this could cause the issue.

If anyone has any ideas of what it could be I would be very grateful.

Have you tried running Memtest to make sure the RAM is fine. It could possibly be a power issue looking at your specs if the RAM is ruled out.

Sounds like a PSU issue.

Check voltages in the BIOS to make sure they're normal and set everything back to stock settings.

As Terbinator says, use memtest to test the RAM first. If it passes then you may want to check your CPU next, this can be done with Prime95 on small FTTs. You could then check CPU + memory together with OCCT or Prime95 on blend test. If those tests are fine then try Furmark or Afterburner to test your graphics card.

If it fails any of the tests it means either there's not enough voltage being supplied or the hardware that failed is faulty or perhaps a power issue as people have stated but to be honest that PSU should provide enough watts for your system.

Sounds like a PSU issue.

I agree....almost certainly down to that PSU.

Hi Guys,

thanks for the replies. I tried the tests Ulti suggested and everything seemed to be fine.
I tried playing an array of games such as TrackMania, no problems, Modern Warfare 2, no problem, yet then tried playing RollerCoaster Tycoon 2 and after about 40mins it froze.

[lazer]

That could point to ram issues.

Hi guys sorry for the very delayed response. I have ran the tests that have been mentioned and found no issues with RAM, PSU, Graphics, CPU or hard drives. I think I may have narrowed it down though. It only seems to happen when running games in full screen.

[ehhhhhhh]

as a last resort you should try a clean install of win7 ;-)

@ehhhhhhhh

Indeed i'll keep that in mind lol, that was the last resort solution I had in mind too well + dishing out to buy a new psu lol

also an update on situation, this has happened once or twice before where my desktop and also sometimes my window 7 widgets/gadgets will mess up. See pic below to see what I mean...

What did you use to check CPU and RAM, and for how long did you test them?

[taowu]

@Tonka777

RAM I used Memtest86+ and ran it 3 times at 2 hours, 4 hours and 8 hours.
CPU I used Prime95 and allowed it to run for about 4 hours and same again to test CPU and RAM
