DFI LanParty P45-T2RS no display, restarts 4 times then nothing?!

[Joe90k]

Hi Everyone,

I have been messing with my machine best part of today, I recently had a leak which made my Asus P5Q-VM die so had to buy a new mobo. I bought a DFI Lanparty JR P45-T2RS off eBay from a guy which is in perfect working condition according to the ad and from inspection. He also had 100% feedback so I am confident the board is fine. However I have put it in and wired everything back up and no matter what I do the computer starts and then restarts four times for around 10 seconds a time and then stays on constantly. If I have no RAM or CPU installed it starts, stays on and does not reboot 4 times. Nothing is displayed through the graphics card and the fan on the card does spin up but as I said nothing is displayed.

When my leak occurred is it likely that the CPU is dead? Or that the graphics card is dead? or RAM or a combination? Only the area around the CPU was wet as it leaked from the CPU block and the leak wasn't too bad. As I said I have tried without RAM and CPU and it does not reboot it just runs but still nothing displays. Is it worth buying a new graphics card?? I was planning on replacing the ancient 3850HD sooner or later but being as I don't game I only use the computer for CAD and light render work it is only lightly used.

My spec is in my sig. Any help is appreciated!

Thanks

Joe

your sig is not showing

not sure what you mean by - [font="Verdana, sans-serif, FreeSans"] [/font]If I have no RAM or CPU installed it starts, stays on - what starts?

make sure the jumper on the back of the IO port is still present

Sorry, I meant as in if I remove the CPU and RAM and just run with the graphics card, and motherboard it will turn on and stay on, it won't restart four times as it does when the CPU and RAM are in.

make sure the jumper on the back of the IO port is still present

What jumper do you mean? The CMOS clearing jumper? If that is what you meant it is still there. I checked both jumpers are in the right place and tried them in various combinations.

Thanks for the replies.

hmmm .... try checking the following things

- is the 8 pin power connector for the CPU plugged in

- are the DIMMS in the right slots

- is the CPU properly seated

- are the front panel connectors (power and reset switch and leds etc) in the correct positions

- check the underside of the board is not shorting anywhere on the chassis

I may be wrong but I don't think that the graphics card will display anything without the CPU and RAM installed - does the board have on board graphics - maybe try to get the CPU and RAM working first - then add the graphics card to the mix.

Checked all of the above to no avail. So I took the board totally out of the case off the mobo tray of the Lian Li V350 and hey presto it started. Put it all back in and it still works. However I have now come to the conclusion that the RAM is faulty. Or that the board is configured wrong or sensitive to the RAM? I Have 4 GB Corsair XMS2 PC6400 in 1GB DIMM's. If I use just one stick in any slot it posts and will boot, however if I try and add another DIMM to either a dual or single channel slot it will sometimes boot but not always. It will never post with more than 2GB of RAM installed though. I'm not sure if this is because my RAM got wet? Or that the board doesnt like corsair RAM. I am going to try a BIOS update to see if it helps then I will test the RAM in another rig to see if I can find a fault and if I do, I will get some more. Does anyone have any ideas based on that?

Thanks

Joe

make sure the ram is properly configured if using all four slots

@Lasher

Thanks for that manual link, I did look at that yesterday and made sure it all matched.

Just found that thread. Seems I'm not the only one with this issue. My RAM is identical to his too.

However when I ordered the first set a while back I was sent 5-5-5-18 T the next set were 5-5-5-12 T But they are the same make (Corsair XMS2 2x1GB Kit)

So I think I will be finding some more RAM!

Anyone got any suggestions for decent 1066MHz RAM that will match a QX6850 CPU? I have a good watercooling loop in atm that should handle that chips potential and seeing as they are reasonable on eBay now seems silly not too, 3.5GHz+ Quad Core???
