PC has become game unstable please help.

Everything is the same as before besides the board. A fresh install of vista cured the BSOD I was getting. I will have curupted all my games then.

Everything back to stock, RAM underclocked to 800. Im going to try 4 gig RAM instead of 8.
 
Also the P5Q needs a lot of volts for the nb when using 4 sticks of ram.. or at least my board did.
 
Ok i can tell you what fixed almost this exact problem for me, its a firmware update you need for your Saphire 4870 graphics card... but then as i look for a thread to point you towards... http://forums.overclockers.co.uk/showthread.php?p=13041374

i see you've already done this update?

Nope this update is not for my card.

It fails with 2 sticks in.

I have reflashed the bios to the latest.

Installin CATs 9.4
 
ok uninstalled the Cats and installed 9.4s
Just ran Crysis demo and the Crysis benchmark tool set to do 50 runs. PASSED.

Question could my ISP have anything to do with it.

will run memtest over night.
 
Hey Clairvoyant, I had the HD4850 running on an ASUS P5Q-Deluxe last year and it was a sweeeeet combination, CD-Drivers, latest CATs it didn't matter the combo worked 100% perfect.

If your system is crashing games even when the system is set back to stock It really sounds like an erratic PSU error or a corrupted game install or a 4 sticks of memory issue although I would have thought four sticks would just plug n play at stock? :confused: (I've never used four sticks of DDR2 in a system).

Good luck man and keep us posted, overclocking is a fun hobby but sometimes you do get burnt, it's all part of the learning curve, no pain no gain lol! :p
 
10 passes of memtest with 4 sticks of RAM in.

PSU tester ordered. (just gotta remember where I got the PSU from lol). What if the PSU is ok.
 
Yup that PSU looks A1 Tip Top! (the tester will beep and flash if something is amiss btw).

Ok so the PSU is out the runnings, looking at either the Motherboard now or perhaps the GPU.

Just for the record, can you elaborate a bit more as I am trying to see where the problem began? Did you Install your O/S while overclocked to 4GHz? you said something in your earlier posts about having a BSOD issue so you reformatted?
 
ok

Everything was fine in the abit IP35 Pro.

I then swapped everthing to the P5Q-E (was told everything should work fine) was getting all sorts of BSOD. (after installing the P45 chip set drivers)

So I reinstalled vista. Only had 1 BSOD (something about PTEs) last night.

I have allways installed vista with a clocked system.

Any other way to test the GPU as it passed 50 runs of crysis.

edit temps while runing crysis were all between 85-97 (VRMs were the hotest)

So you just swapped over the pieces to the ASUS board and attempted to clock it straight to 4.0GHz?

And that's when you started having BSOD? or? :D

The bit I'm not clear on is how did you know how to set-up a 4GHz overclock on a brand new board? :confused:

that is correct, then I did a fresh reinstall with a clocked system.

Reading on these forums before I changed boards.
 
Ok well the possibilities have just escalated much! :p

We all got our own ways of going about these things but personally I wouldn't have done what you have just done heh! :o

The easiest thing would have been to swap your kit into the ASUS board, then loaded BIOS defaults and started from there. The situation is harder now because you cannot tell if the error is hardware or software because you installed it all on an unstable system . . . . :(

In your boots I would start again, reset the BIOS back to default, wipe your disk and start again, install everything on full BIOS [Auto]. Once your OS is installed with drivers and stuff make a good backup so you don't have to do this again!

And I would do that with just two sticks to be extra extra safe, if the system still crashes games after a stock installation your ******* ;)
 
How did I know you was going to say do a fresh install on stock bios settings.

Well I gotta do something as I cant play any games at this time.

I will let you know in a day or 2.
 
So far so good had a couple of games on BF2 no CTD (only short games).

But the PC now seems to take a bit longer to come out of sleep than it used to.
