Hello all, many thanks in advance for any replies.
So, a few weeks ago my computer crashed and restarted itself after playing a game. The screen corrupted. However, when it restarted it was garbled from even the bios. Windows does start up but it does not display at the correct resolution and is multicoloured and distorted.
So thinking this was graphics I replaced the card, no change.
So I replaced the motherboard, processor and ram (i was due an upgrade), no change.
I switched the hard drives around (there are 2) so that it attempts to boot from only the 2nd, no change
I checked the monitor with another computer, no difference!
I really do not know what is going wrong. The only thing I can think is that it really is the screen as I had to try it on the VGA connection rather than the DVI connection which I have to use on my computer.
Can anyone think of anything else it could be? The only other component to replace is the PSU!
The OP Stated, "Windows does start up but it does not display at the correct resolution and is multicoloured and distorted." So Windows doesn't work right.
If you put a new video card in, you may need to uninstall the old Video Card drivers. Then install the new drivers after running Driver Sweeper or something similar. This will ensure the video drivers are installed right. This could help with Windows being messed up.
However, if the POST screen is garbled, then drivers are NOT the problem. The POST screen shows up long before the PC loads anything into memory.
Based on the fact that you've replaced everything else. You either have a PSU problem or a bad monitor. Were it a PSU problem, I'd bet you'd have stability issues causing crashes as well.
I'm confused about your reference to VGA and DVI. You had to use the VGA connection because the DVI was being used on your computer??? Does this mean you're trying to display all this on a TV? That can open a whole different can of worms when it comes to image distortion.
EDIT: I looked at your screenshot. Looks like a Samsung monitor as opposed to a TV. Correct me if I'm wrong though, case hooking up to TVs can be tricky. The error message that's showing up on your screen, is that normal? Or did that happen recently too? It appears that file is for an Apple Mobile device program. That ultimately means the garble that you're seeing is actually a hypnotic beam being emitted to convince you to buy more Apple products.
