I have just built a pc, when i power up it shows processor and ram ok shows ram frequency then reboots. this just cycles through until i power

Whats your specs?

Sounds like you might need to increase RAM voltage or something along that lines.

Mobo is DFI Lanparty 875p-t, cpu is p4 ht 3.0ghz, 512mb kingston ram, 600w psu.

Anyone got any ideas? I've disconnected everything ,removed the cmos battery and moved the jumper, this should reset it right?

Jokester · 19 Sep 2006 at 20:32

I would download Memtest86 and put it on a floppy and run that for a few loops and see if it picks up any RAM errors.

Ok thanks, could a ram problem stop me from being able to enter the bios thiugh?

Jokester · 19 Sep 2006 at 20:42

Ahh, ok, so you can't get into the BIOS either? In that case Memtest won't help as it won't get that far.

Just one stick of RAM? Try it in another slot.

I have tried two different makes of ram in each slot, the problem i get is that themachine "posts" and then just restarts, if i press anything on the keyboard then again it just restarts effectively meaning i cant get into the bios.

Sounds like somethings duff, are you able to test the CPU/GPU/RAM in another machine?

Jokester

ash_91 · 19 Sep 2006 at 21:06

GPU and RAM are fine, tried and tested in another machine, i do not have another socket 775 motherboard though.

Raikiri · 19 Sep 2006 at 21:06

What brand PSU is it?

ash_91 · 19 Sep 2006 at 21:10

Seasonic, its working fine in another machine of a similar spec though.

Raikiri · 19 Sep 2006 at 21:12

Seasonic PSUs have issues with some DFI boards afaik but I don't know if yours is affected or not.

ash_91 · 19 Sep 2006 at 21:13

Ok would it be worth trying the psu from my sony vaio machine then?

Raikiri · 19 Sep 2006 at 21:14

Long as it is powerful enough to run that system (I would say 250w+ depending on the graphics)

ash_91 · 19 Sep 2006 at 21:15

The psu should be powerful enough as i have gone down to my radeon 9200 and 512 of ram just to try and get the thing to boot!

Tetras · 19 Sep 2006 at 23:56

Won't the PSU in that be a custom jobby? Wouldn't have thought it will work myself..

Incorrectly seated heatsink/cpu?.....at a long shot... :eek:

That suddenly crossed my mind last night as this is my first build, I thought there was a thermal pad on the heatsink but im not so sure now be cause it was so thin.
If i take a picture would someone be able to confirm if i need some thermal paste or not?

A picture is worth more than a thousand words.
