Randys Posted October 12, 2005 Posted October 12, 2005 Got all my parts from newegg 5 days ago and have been working on getting things working since then. Been up all night 2 nights now and I'm not getting my work done. I need help. Initially I had problems with the dual channel DIMM's and video would sometimes become corrupted. Was getting all kinds of BSOD and errors in windows. Finally got DIMM problems fixed with 623-2 bios, optimized default settings and yellow slots. I let memtest run for 8 hours with no errors. No more BSOD and errors. I have turned off everything I could in the bios (com port, irda, audio, 1394). The video problems still happen in windows xp. It sometimes occurs when I get to login screen. If I get past the login screen without problems then I try playing quake3 or doom3 to stress the video and it usually eventually becomes currupt and locks up. I am using 78.01 forceware drivers. Bios settings are optimized default. I have all 4 power connectors (24 pin, 4 pin, hdd type and fdd type) connected to the motherboard. I have the 6 pin power connector connected to the 7800 gt graphics card. I have tried moving the video card to the other pci express slot but it made no difference. I am using the dvi to vga adapter that came with the graphics card as I like my old 21" iiyama vision master and don't have money for a new monitor. I'm now wondering if my PSU isn't enough. Please check my signature and let me know what you think. I need help and am about to call newegg but I'm not sure if the video card is faulty or if I chose a PSU that doesnt have enough power for my video card, motherboard and cpu. Maybe I need to change a bios setting? Help. Thanks. Share this post Link to post Share on other sites More sharing options...
Boppo Posted October 12, 2005 Posted October 12, 2005 That PSU should be able to run your box. Share this post Link to post Share on other sites More sharing options...
Randys Posted October 12, 2005 Posted October 12, 2005 It's good to hear that the PSU should be ok. I researched what parts to get for this computer for a long time before buying them. I'm now wondering if the video card is the cause. Funny thing is I have had the computer going for over an hour now, using it to write and check these forum messages and have had no video corruption yet. Now if I start Doom3 I'm pretty sure it will lock up. Once I'm done downloading 3dmark I will try Doom3 again. When the video corruption happens in xp I get groups of horizontal lines of dots, which are mostly white. These groups of lines are usually about 1/4 of an inch in width. I'm running 1600 x 1200, 75hz. The more I move my mouse around on the screen and use windows the more of these appear untill it becomes hard to tell what I'm doing. In quake3 I got the same looking lines without the lockup. In Doom3 it usually locks up shortly after they start appearing. BTW I added my case (Antec SLK3000-B) to my sig.

Grazzhopper Posted October 14, 2005 Posted October 14, 2005 Case temps?, my 7800gtx OC runs at 52 C, 7hours 40 minutes of full load (pcmark05) Case temp 38 C. CPU 39 C Given the cards are rated to 115 C, I would guess your 7800GT is faulty, easiest way to test is plug it into another comp. If you use DirectX diagnostic utility do you get issues with "Direct3D (test's 8 & 9)"? Share this post Link to post Share on other sites More sharing options...
