MONKEYmark Posted December 27, 2005 Share Posted December 27, 2005 hi just been having problems with pc`s lately so thought i would upgrade a bit. only mainly use pc for surfing and msn.dont really bother with games but would not mind trying some. my old system amd 2000 chip (1.10mhz) 256 meg ram 1x 200 meg maxtor ide 2x 300 meg maxtor ide (just bought) 8x8 pioneer dvd writer 64 meg nvidea gforce 2 mx400 4 port usb hub pci card 2x 10/100 network cards soundblaster pci 512 soundcard been having intermitting troubles.so decided to upgrade a bit. had old comp a few years and built it myself.the old pcwould not see my 300 gig hard drives,had to partition to smaller sections.but a newer shuttle small case pc would see them ok.think it was something to do with bios in old motherboard. just bought biostar n4sli-a9 motherboard with twin pci express slots.(socket 939) amd athlon 64 3500 64bit 2x 512meg corsair ddr400 mem 1x 128 meg ddr300 winfast px6600 gt tdh graphics card new tower case with 500wat power supply also got a hiper power supply 425 watt pc specs have changed a bit since last time i built one,know nothing about pci express cards.just know sli runs 2 gfx cards in tandem for better performance. i built it all up ok and come to power on machine and got case to light up and power but got no display.not getting any error beeps. anyone have any ideas where im going wrong. tried the memory in another comp and thats fine.cpu can only go in one way and fan on cpu spins up and case lights up when you power on. just not sure with pci express gfx cards.whats the small blue slots for? tried it with hardly anything plugged in.also been reading up about running memory in dual core i think it was called.it says on net you put memory in dimm slots 1 and 3. the memory slots are blue and cream. does the gfx card have to run at a certain voltage to work? i bought all parts from same shop.so dont think they would recomend something that would not work.shops not open till wednesday so cant ask for advice in technical department. has anyone tried out the new windows xp64 os thought i would see if any it guys know what i doing wrong thanks Link to comment Share on other sites More sharing options...
MattSZ Posted December 27, 2005 Share Posted December 27, 2005 Check the motherboard is mounted correctly and not touching any metal if possible set it up on a plastic sheet out of the pc case. Link to comment Share on other sites More sharing options...
suprasport Posted December 27, 2005 Share Posted December 27, 2005 if there is no beep on start up then it is probably your proccesor. is your hd powering up. Link to comment Share on other sites More sharing options...
osso Posted December 27, 2005 Share Posted December 27, 2005 i'd make sure you've got a 4 pin power connector plugged into the motherboard to power up the processors and that should actually kick off the bios display, also make sure you've got power plugged into the graphics cards Link to comment Share on other sites More sharing options...
Pixelfill Posted December 27, 2005 Share Posted December 27, 2005 sounds to me like power required on the graphics card. I would expect there to be a light blue 6 pin connector on the PSU which should slot into a blue 6 pin hole on the graphics card. Failing thatt the Graphics card may have come with a double molex to 6 pin PCI-X power convertor. If you need to use this connector make sure that the two molex connectors are plugged into different "branches" from the power supply. These are the same symptoms that we experienced when we forgot to power the gfx card good luck Mike Link to comment Share on other sites More sharing options...

JamesG Posted December 27, 2005 Share Posted December 27, 2005 Sometimes it helps to clear the CMOS if it doesn't boot up. Remove the battery and move the CMOS jumper to the clear position for a few seconds. Then put them back and see if it boots. Link to comment Share on other sites More sharing options...
Pixelfill Posted December 27, 2005 Share Posted December 27, 2005 hi did not know you have to power gfx card. all new items are retail boxes. the gfx card came with dvi to vga adapter vivo cable for input/output Some graphics cards don't, seems to be the high end ones which require extra power. typically nvidia 6800 GT, 6800 Ultra, 7800 GTX, and the high spec Quadros. I guess there are more, but these are the ones that spring to mind. Have you connected a "Molex" to the motherboard by the PCI-Express x16 slot. I would suspect that this will provide the surplus juice should any PCI-E card require it. Mike Link to comment Share on other sites More sharing options...

Mikehi lol whats a molex. god i feel so out of touch with hardware.i used to be up on it at one time.used to go to all the computer shows buying new hardware,they change so much. just got to a stage when the computer was doing everything i needed and seemed ok for what i was using it for. going back to shop where i bought all bits from to see where im going wrong. hope none of the hardware is faulty, had that before.built a few pc`s over the years. thanks for help and advice xxx xx x Link to comment Share on other sites More sharing options...
MONKEYmark Posted December 28, 2005 Author Share Posted December 28, 2005 just looked a molex power connector is a standard ide type connector, i have connected a power cable to the board but did nothing.i read in manual it was more for if you are running in sli mode to supply a more consistant power supply to both graphics cards, hope nothing is faulty.i took my time connecting motherboard and parts. built a few pc`s over years. would like to know where im going wrong thanks mark Link to comment Share on other sites More sharing options...
