Maxx Posted January 14, 2006 Posted January 14, 2006 Ive just done a new pc install, connected everything up and turned on the pc but I dont seem to be getting any video display. I have changed slots for the gfx card, changed the gfx card over and put in different sticks of memory to no avail I have been looking through the guides on here but havent managed to spot this problem with anyone else but I have found out I haven't connected one of the power cables to the motherboard. I am also going to buy some decent 2gb ram as the current ram in some old ddr400 value but still works fine in the system I am using now. Once I have done the above and the problem stays the same is there any other way to sort this problem out? is this a common problem?? I one see any leds apart from one next to the ram sticks that goes on as soon as it turns on. Hope somone can help - sorry for being a complete noob :/ Quote Share this post Link to post Share on other sites More sharing options...
stanggt00 Posted January 14, 2006 Posted January 14, 2006 Try powering up the system with ONLY 1 stick of ram in the top orange slot, the video card, mouse and keyboard and see if you can get it to POST (POST = Power On Self Test). If so, go into the bios and load optimized defaults, select your PCIe card for the initial display and change the max payload (4096 by default) to whatever the Ram is on the card (256 or 512). Hit F10 and when it powers down for the restart, turn it off. Then try hooking up your hard drive and CD rom, see if it powers up. If so, keep plugging everthing back in. If it still POSTS, go into the CMOS, then genuine bios settings and at the very bottom, enable memtest. Once in memtest hit c, 1, 3, 5, enter 0 and let it run for 20 passes. If it passes that with no errors, hit c, 1, 1, enter, 7 and do 1 full pass of all tests. If you have any errors in memtest, you may need to increase the Dram voltage and or loosen the ram timings. Hopefully it will work fine from there. If not, your PSU may not be up to par. I dont recall seeing that brand listed in the recommended PSU list.

Maxx Posted January 14, 2006 Posted January 14, 2006 Thanks for the quick reply and advice. I think my psu should be good enough as can have Sli plugs in and is comptable with 24pin motherboards but would need someone to confirm this. I will try again tommorow with all the plugs in and using just one stick but I have tried with 1 stick today (used 3 different sticks in all) but to no avail.

stanggt00 Posted January 14, 2006 Posted January 14, 2006 When you say compatable, do you mean it has the 20 pin plus a 4 pin, or is it a native 24 pin connector? These boards are VERY picky with power supplies and require a +12V rail @26Amps minimum for non SLI and 32A for an SLI. It very well could be the PSU.

Maxx Posted January 14, 2006 Posted January 14, 2006 It has a 20pin + 4pin connection. Unfortunatly I dont have another psu with a 24 pin connection to test it with or know anyone that does sadly Quote Share this post Link to post Share on other sites More sharing options...
stanggt00 Posted January 14, 2006 Posted January 14, 2006 What are the specs on the PSU. They should be on the PSU and tell you how many amps it's giving on the 12V rail. Post up the specs of it if you could. Quote Share this post Link to post Share on other sites More sharing options...
red930 Posted January 14, 2006 Posted January 14, 2006 Tagan makes a very good PSU. But that doesn't mean you're particular unit is running perfectly. Use the build guides.
