I have been noticing stability problems in the past few week. My integrated network card has gone to hell and i always loose my internet connection. Even when my brothers pc on the same router and with same cables does not.

I have been haveing stability problems which really started to occur when i got my new memory. I upgraded from ocz pc4200 2x256mb to pc4200 platinum ocz 2x512mb. Now I get random restarts and my system just forgets information. Such as the bgios just resets or it will forget saved data. resolutions change by themselves back to default. really wired stuff. At first I thought it was my Memeory. But the memeory ran fine with a 34 hr memtest86 3.2 v test. The memeory was at 2.5 3 3 8 and 266MHz. what it is rated at and it was fine.


I ran 50 loops of 35mark05 and the Video card was fine. I ran WD diagnostic tests and all HSS were fine.

My PSU rails are near perfect also.


I recently purchased an ATI x850Xt and the card made my 2D enviorment slower. It went and took 13 seconds to open firefox. But when you cleared the drivers and installed my 9600Xt, it was back to normal. I had 2 x850Xt and both had the same problem. i dont ahve them anymore.



I ran prime 95 and it always fails when running Large FFt's, though small FFt's never fail. i run 2 instances of prime 95 and one always has a hardware failure.


I dont know which usint is going out on me. if it is the Motherboard or the processor.

Perhaps the "General Hardware" forum would be a better place to seek advice?

Did you try putting back your old ram? If prime is failing on the large ffts and is fine on the small ffts then it is most likley the ram. Memtest can test for faulty ram, but you may have a case where the ram doesn't have enough voltage when you're in the OS.

 

[Vinny77]

well memtest runs fine for 34 hours at a 290fsb.

My vdimm is at 2,85

 

[gopunk]

check power supply perhaps? and yea, this doesn't seem highly technical

 

[patentman]

not only does your your computer not work, your eyes don't work. Read the forum postiong instructions before posting. Highly technical only!
