• All of a sudden, my computer starts showing strange artifacts, and then crashes.

I built my computer about 4 years ago, and all of a sudden, it has just started to bug out and then crash. Specifically, the display starts to glitch out. Strange artifacts, white lines on the screen, stretching, tearing, and then it leaves the picture shifted a few inches to the right or left. After a little bit of this, it just shuts down and restarts to some motherboard screen, where it tells me "hyper transport sync flood error on last boot. Press f1 to continue." I have no idea what to do. I've reseated the graphics card and RAM, reset the CMOS battery, and this still happens. I googled it and found a few answers saying something about not enough power, or a bad overclock, but I don't think that can be it because I am not overclocking, and my power supply has far more power (700w I think) than my parts are using. Is my computer dying, or can it be saved? I really wanted to squeeze a few more months out of this thing.
I had similar issues with my pc back in the day. Turned out my graphics card was about to die, resulting in strange artifacts and bluescreens. Sometimes my screen just turned off as well. Then I started happening again and it was due to some issue in my power supply unit, a blade from the fan broke off and jammed the whole fan. Making the power supply unstable. You did everything I would recommend. Although I usually dust off my pc because it can cause some serious heat at times due to my absolute shit fans.
Download HWMonitor and check your temperatures. It's most definitely caused by the graphics card, either it's overheating, or it's dying.

Is there some sort of tool I can run to just generate a list of all the spec information you need? Right now, all I can tell you is the basics. MSI 880GM E41 Motherboard AMD Phenom II Black Edition CPU ( I think it's 3.2 ghz ) XFX Radeon HD 6850 GPU
That's all I need to know. Just download HWMonitor and check the temperatures. [editline]27th November 2014[/editline] Damn, completely missed this in your post: "hyper transport sync flood error on last boot. Press f1 to continue" Might be your processor or motherboard dying, most probably the latter
Shit... I guess I'm pretty screwed then.
It could be a few things: 1) Bad GPU 2) Bad RAM 3) Bad PSU 4) Bad motherboard The first three things I would try are to replace the PSU, GPU and update the motherboard BIOS. A bad PSU can cause all sorts of bizarre problems, and a bad GPU can cause both the screen glitches and the Hypertransport overflow error. You should also run a memory test with Memtest ([url]www.memtest.org[/url]) for at least 8 hours. Sometimes certain regions in the memory can be weak and work fine until they get sufficiently stressed or hot and then they start failing.
Considering the system's worked flawlessly for 4 years, I highly doubt the BIOS is the problem, though
Well, this is either a new problem entirely or a related problem. Along with these hypertransport crashes, the computer just won't turn on now. All the fans will come on, but my keyboard/mouse and display don't. Also, there is no motherboard beep like there usually is when I turn it on. I was able to fix it by removing a stick of RAM. However, it still gets the hypertransport crash. Is it bad RAM in addition to a bad GPU or whatever else? EDIT: I will try updating the BIOS, if the computer can stay on for long enough to do that. I don't think memtest will be an option because it will probably just crash during it, but I think I'll look into it. EDIT 2: Could not update BIOS. Got as far as opening chrome and then I got the crash and the hypertransport error.
My bet is still the motherboard. But you could always try removing the graphics card from the system, and connect your monitor to the motherboard, see if that works [editline]27th November 2014[/editline] Oh, and if you want to repair the system, a fitting motherboard isn't too expensive [url]http://www.newegg.com/Product/Product.aspx?Item=N82E16813135349[/url]
Well I was planning on building a new computer soon anyway. I guess I'll just do it ahead of schedule. Thanks for the help.
