My cousins system would just lock up, mainly during gaming and a couple of times on desktop. The screen goes off thent he keyboard and they system stays on but just hangs.

He changed the mobo but still the same
He changed the gfx card but still the same
We just tried a different psu but still the same

His system now is

Asus P5VD2-VM SE - wasnt my idea
E6300
HD4850
450w no name psu (bad idea i know)
Geil RAM 1 or 2Gb cant remember

I had him run prime95 a while back and it ran fine for hours wih no problems.

I just took a 480w Tagan PSU up, windows loaded ok he booted up CS:S and before he was playing the screens shut off and the 2 LED's on the 4850 were flashing away.

I said install another game but he said it will probably crash during install so we didnt bother.

Any ideas? I cant think of anything else

Thanks

Nick
 
Download UBCD from ulimatebootcd.com or google it and burn to a cd. Boot from it.

Run Memtest+ on each ram stick individually (1 stick in the machine at a time) to test your ram from dos and also run MHDD32 to test your Hard drives afterwards. If there are no problems there check everything is seated correctly, your cpu fan is spinning etc incase of overheat issues.

What does this mean? I had a quick google look but nothing difinitive.

I would assume lack of power or something but you swapped PSU, I would have thought that tagan would have been fine...
I don't think its memory related but would'nt hurt to run memtest.

Guess you dont have a low powered card to try?

I would try to find out what the 2 flashing LED's mean, might just be feed me more power, but the 4850 is'nt realy that power hungry.

Is the system at stock?
 
Paradiso - I'll try and get him to run that.

YoungBlood - there are 2 LED lights on the back of the 48*0 cards

His previous card was an X1800 and it did the same with that.

I just spoke to him and he said it didnt crash running the onboard gfx

System is stock, all fans are spinning ok, temps are fine.

Leans back towards PSU, but the tagan has +12V@28A so should be plenty...I run a GTX on less than that flawlessly. So I don't know.

I remember reading about putting the PCIE @ 101Mhz in the Bios once but I dont think thats of any help here, just putting it out there.

All points to the PSU, but the PSU should be fine, computers - don't you just love em :D

Even if it was working fine on the unbranded PSU he would be wise to invest in a better one so maybe getting a nice Corsair or OCZ could be encouraged? Even if it didn't solve the problem I would not consider it money wasted, if that makes sense....

Hmm thats what I thought, this Tagan was bought off MM so its the only time I have uesd it, its probably a few years old. I will have to get him to bring his pc here and reach my Corsair cables across into his system to rule out the psu for good.
 
makes it seem like the card is causing the driver to crash.
The PCI-E bus set to 101Mhz may fix it. check all the settings in BIOS are what they should be (take off auto if you know the correct settings).
Update graphics drivers.
I would personally have leant towards memory as being the issue over the PSU, as you have tried more than one PSU.
Would be interesting to know what the lights on the card actually mean though, got a manual that tells you?
 
I had a very similar problem after puttng a 4870 into my pc.

This worked for me:
1 uninstall ati drivers reboot
2 run driver sweep to make sure ati gone run ccleaner to clean up reg
3 download and install latest dot net from ms
4 install latest ati driver I think they are 8.7
 
I got him to try mem test with each stick on its own and it didnt fail, he tried both again and it didnt fail either, how strange.

He did this using on board gfx, then he tried the 4850 and no boot, tried his old card and no boot, I think the mobo died.
