Problems with graphics and power

[AWS]

So lately ive been having this problem that visual artifacts appear on my screen every time i start my pc. When i start the pc, some parts of the letters are more colored white and bold than the rest, so i think the artifacts appear already in the beginning.

When i use 32 color(True color) in the display options, the artifacts are colored light blue on every light shade and when i use 16 color(high color) then they are transparent and pink. Also if i install my graphics driver on and play windows media player

then it crashes and the screen goes black with a message: Power saving mode. Hmm where to start, umm the first thing what happened after everything was okay was that i was listening to music and watching youtube videos, everything was fine and suddenly when

my brother started talking on the phone my screen went black: power saving mode. This has happened before but then it when on power saving mode not after loading os screen(about some weeks ago) i didnt know what to do and fixed the problem just by moving my

pc a little(by 45 degrees) and i blew some cool air into the power supply thingy and it was gone, but then i had no artifacts. Everytime i started my pc, the screen went black: power saving mode after the windows os loading screen. After some attempts to restart

and in hopes itd go back, the artifacts appeared. I could go into safe mode, where it was on vga mode and artifacts where there too, they were everywhere, but when i changed my screen resolution in safe mode to a higer one, everything was still okay till i

restarted and i couldnt enter safe mode anymore: the screen was black and i could see and move my mouse pointer there. I panicked: restarted, spammed F8 and did a system restore under repair tools to an eariler point(7 days before) and i could enter safe mode

again. I had windows 7 ultimate 64x bit on then. I am not overclocking(checked BIOS), put the "go into standby mode" option to never(doesnt work), I reinstalled graphics driver(doesnt work). When i uninstalled my graphics driver i could go into normal mode

again. Then i thought maybe the issue was in os configuration, i used my old xp dvd to install windows xp on(clean install)(didnt fix it), but now i can go into normal mode with the graphics driver on but if i use higher resolution it crashes and power saving

mode, so yeah this is whats been happening and i dont get whats wrong.

i got lots of cables and tried a different monitor(didnt work) so the problems definetly in the pc. I also tried using another powersupply cable and dfferent locations. Im using a vga cable right now and its very tightly connected. I tried resetting my

video card, cleared the dust off from everywhre, resetted bios with the battery thingy, tried using different ram, less ram, so it must be either power supply, GPU, video card or(dont think so) motherboard

Some info:

using nvidia geforce 7300 GT videocard, flatron LG monitor, 2,5GB RAM(dual), award modular bios v6.00PG, system model awardacpi, 149GB harddrive, 5GB used atm, intel pentium D CPU 2.8Ghz

also i looked for my gpu and found a similiar thing on my motherboard which had a black cover on it and said intel, so i think the thermal paste option is out, the system isnt making loud noise, cpu temperature at 49degrees Celsius, video card was hot

before, now its kinda warm after using the pc, fan RPM 2200, oh and when i want to check which video device im using, its all N/A no information, like the video card isnt connected and yet it is, and when i use the device manager to check it, then theres avg

general video device
