Hello all,

Got my new rig about 4 weeks ago, overclocked it to 3.04Ghz and it was stable as a rock passed all Orthos test, temps were 30's idle 63 load. Anyway all of a sudden games started crashing and now I cant even load one. Ran orthos again (blend test) and it keeps crashing alwasy a different core, also windows somethimes has a blue screen of death and does a memory dump. Passes Orthos test if you just stress CPU or just RAM. So I set PC back to stock settings and its still crashing/ failing Orthos. Re-installed windows too and still same. Any ideas?
 
sounds like something has degraded to the brink of failure ?

Run Memtest on each stick of Ram at a time, check for errors overnight.
What is your PSU?
 
hmm , a lot of relatively new ones have failed...the forum is littered with posts of failing hipers....can you check the rails ?
 
Also get this error from Orthos
ERROR: ILLEGAL SUMOUT
Possible hardware failure, consult readme.txt file, restarting test.

Where does the readme.txt file live?
 
No thats beyond my skills unless there is a simple way to do it?
Would be good to use a PSU tester on that Hiper, if you don't know anyone who has one you can buy them for about £12 (Antec make the lowest price one I think?).

The trick with trouble-shooting is to never assume anything.
 
Been running memtest now for 4 hours and its rock solid no errors. But... Took me an age to get PC to boot up this morning kept restarting sometimes after post sometimes when windows logo comes up and had a few BSOD's as well but it seems to be OK now but would'nt want to try loading a game.
So I guess now my RAM is fine, am going to try another PSU later today or tommorroe or do we think it might be northbridge?
 
Have contacted supplier they have told me to try this, what will it achieve?

Please carry out the following procedure:

Remove the motherboard from the case, remove everything from the board apart from the CPU + heat sink and then clear the CMOS (refer to your motherboard manual for how to do this).

Place the board on a non-conductive surface, plug in the main power connector (usually 24 pin) and any extra power connector (4pin or 8 pin) the case speaker and the power button, and power the system up.

Depending on the board, you may receive a series of POST beeps. Make a note of these.

Add a single stick of memory and power the system again, noting the result.

Finally, add the graphics card (if using one) and again note the resulting POST beeps.

Additionally, try swapping as many components as you can with other compatible components (PSU, motherboard, CPU, RAM, graphics card) to try to pinpoint the problem.

If you receive no POST beeps at any point or the POST beeps don't change when you add a component, then please contact us.

Note: Some motherboards have voice instructions detailing the problem, such as "CPU not present" and may not have beep codes. In order to hear these, you would need to have speakers connected to the speaker output on the motherboard (if present).

I had a 580watt Hiper PSU for about the same time as yours (13 months) , then my PC started to reboot or didn't want to start up . After a short time like this, the PC wouldn't boot up and it turned out to be the Hiper was faulty . I chose not to RMA it and put it in a skip because I had no intentions of fitting another one since there were quite a few going wrong. I was just glad it didn't take out any of my other components.
