Hello there, as this is my first post feel free to correct the location I have posted in or any other forum specific mistakes I have made.
But on to the problem, I recently built a system for a friend whos only intrest was watching movies and working with large files in photoshop CS5, he wanted to have a machine that would last for a while so i set about getting these parts together, please note that this fellow is uninterested in gaming.
intel i5-750 CPU
gigabyte GeForce 210 (pithy graphics card)
4Gb kit (2X2Gb) DDR3 2200 mhz G-skillz RAM
gigabyte GA-P55A-UD3P motherboard
2 TB WD HDD
600W HuntKey PSU
I built the machine with no trouble at all and after installing a brand new copy of windows 7 it had no problems, then after i finished installing a few drivers (mothorboard/graphics card) and restarted, it started showing horizontal red lines about 1 pixle wide across the screen along with single red pixles. the lines occur mostly when an image is on the screen and if a video is played the screen cuts out and seems to turn on and off. i rolled everything back, uninstalled all the drivers and such and still the problem remained. it even shows the red pixles and lines on the bios splash screen now.
so i changed out the video card for a known working ATI 4850, same problem, though now windows often wont even get past the loading screen, it just resets and loops. switched back the graphics cards and i could get back into windows. which seems to run fine for a while then the screen goes all screwed up slowly worse and worse untill the screen starts loosing signal intermittantly and then the machine crashes, which sounds like overheating, i have CUPID HWmonitor this states that the GPU is running at 36C while essentially idle. this could be a false reading but the card itself feels only slightly warm to the touch.
so i still had the same artifacts with 2 different video cards, but the system would only run properly on the 210. so i swapped out the ram, tried each chip individually, no difference. so i changed the PCIE slot, no change. the system seems to sit stabally while viewing text but as soon as pictures or video come up it crashes soon after, which is no good for a machine to be used for just these purposes. i have installed all the drivers that came with the video card and motherboard, and i have updated the drivers for the video card from the website with no change in symptoms, all bios settings are default.
before i start fiddling with voltages in the BIOS can anyone help with pinpointing if this is a conflict issue, or faulty hardware or something along those lines.
Thanks in advance for any help regarding this problem.
