First of all hello everyone.
After months of looking around the forums, searching the web, trying every possible thing i could think of, thought my last resort after a year was to post here, where in my opinion should be the best of the best who can maybe shed some light into my problem.
To start with the initial problems, what i remember at least, as it's been over a year since.
The PC while booting had strange artifacts displaying on screen during POST and on Windows, the artifacts were strange letters/numbers during POST and strange vertical lines/dots during windows loading and when fully loaded. Kept freezing, restarting and i believe there were some occasional BSOD. I assumed the GFX card was going bad so after a while of saving up, got a Nvidia 450 card. First boot i don't remember what happened exactly, either no boot at all or still the artifacts, but somehow it booted up sometimes, but when it did boot, still had same problems as before, rebooting, freezing, plus and additional error, having to switch to safe mode as the pc didn't want to boot into windows, and when checking the device manager, the card wasn't recognized, artifacts still persisted, again after reading on forums found that it could be the PSU, replaced that eventually as well, still same problem. Now it's not even doing that anymore. PC doesn't boot at all, nothing appears on the monitor, fans spin, lights turn on, but no PC beep. The phase LEDs stay on red and nothing happens. I tried booting with minimal hardware (GFX card, 1 slot of RAM, everything else disconnected) but no change. I removed the cpu cooler and CPU, to see if there's anything visible on that and if it could be the cause. CPU looks fine, however the cooler's plastic legs seems to be broken, there's only 1 out of 4 legs that still has the pins intact. I reapplied the paste, put the cooler back on (even though it wasn't properly seated because the cooler only had 1 leg to hold it in place) and tried switching it back on. Was constantly rebooting, with further testing, removing the 12V 4pin from the motherboard allowed it to boot, plugging it back in gave same result as before, constant reboots, stayed no more than 1 or half a second on. I eventually removed the cpu again, put it back in (no more paste however, reused old one) and it was working. Then tried the bios restoring method, connecting the pins, thinking the bios is dead, but that didn't help either, the PC was rebooting while the pins were connected but no beep. Maybe i had to keep trying and holding the pins for hours but i can't do that, don't have that much patience.
I tried to be as precise as i could on what i did and what was going on in the PC.
I'm tired of random replacing stuff, too expensive to go on trial and error, so if the PC can't be fixed, at least if someone can tell me what the real problem is, what's dead and what needs replacing.
System specs:
CPU: Intel Quad Core (don't remember exact specs but i think it was 2.4Ghz Q6600)
M/B: Gigabyte GA-EP43-S3L
RAM: Kingmax 2GB DDR2-800 x2
GFX: Leadtek nVidia GeForce GTS 450
PSU: Inter-Tech SL-700, 700W
Thank you very much all who try to help in advance.
