I've been having this issue for a while, and I just can't narrow down the problem. Basically, my computer occasionally blue screens when under load (usually when in a full screen game, doesn't seem to matter how resource intensive the game is, happens on LoL occasionally, and recently often in skyrim). If it doesn't bluescreen, it just reboots without the blue screen. There's no useful error message in the blue screen. it only flashes up for a split second before rebooting. This leads me to believe there's always a bluescreen, but sometimes it flashes off too fast for me to see it. Now originally I was confident it was the memory. Although it passed memtest and most other tests, sometimes it crashed during memtest. After a long period of removing one of my 6 sticks of ram, and using the computer for a week to see if the issue reoccurs, I *think* I narrowed it down to the second of the 6 sticks. After removing it and continuing with 5 sticks, no issues for a few weeks. so I filed with corsair, got the 4 replacement sticks yesterday, switched them out so the machine has all 6 again, and as soon as I booted a game, bluescreened/rebooted after 2mins in skyrim and about 4 times in an hour in LoL. After I removed the second stick again, no issues for another hour. So now I think the slot on the motherboard has the issues. If these problems ring a bell in someones head as to what it could be, feel free to pitch in. sidenote: I also get another issue where randomly I'll get kicked out of any graphics card utilising issue (media player, game, whatever), with the standard "graphics card drive has encountered an issue and restarted" message. This isn't a drive issue, as it's been happening for a while now through several driver versions. So maybe an issue with my GPU too. So, here's my question: My PC has the following spec (3 years old now): Intel I7 2.6ghz 24gb 1600mhz memory Asus Deluxe V2 motherboard Nvidia GTX295 non-modular power unit. probably something like 800w. SSD hard drive. It can run most things at full spec, so it's not out of date. But, I was always of the opinion replacing the motherboard is a major hassle, as I'd have to buy an old one to be compatible with my parts, and I begrudge spending money on something that isn't current generation. Should I be attempting to repair, or after 3 years should I be considering a whole new build? (only part I would keep is the SSD).
