Hello guys, I was hoping if I could get any help with a very weird problem. My computer has been misbehaving lately and in the mornings it takes literally 20 attempts to get the thing to boot. When it does boot, it usually runs fine for the day, sometimes I get a BSOD (I'll provide the ones I've had so far) and sometimes the computer will just suddenly turn itself off. Right now, it's turning itself off ALOT. And I can easily replicate it by playing a video. When I play a video it seems fine, as soon as I go to stretch the window of the player (VLC Media Player, but happens with Windows Media Player too) the computer shuts off. Everytime.
Further testing shows it did it the most with a .mp4 video, also, it doesn't shut off in safe mode...
I've checked CPU temperatures, and they are around 55C, 65C at the very most. (Fine for a Intel Core 2 Quad Q9550, should be able to handle a max of 70C)
I've checked GPU temperatures and it's at 50C-55C (Seems fine for an ATI Radeon HD 4870)
I've reseated RAM sticks, doesn't make a difference
Am I looking at a PSU problem? The BSOD's always seem to suggest faulty RAM, but I think that too might come from a dieing PSU.
I've been troubleshooting to look for faulty RAM sticks, doesn't seem there's a bad one in particular, I've run with just a single stick, trying one stick after the other, nothing really helps. Sometimes it seems like it's going better but then it just catches me offguard and shut off again. Also, the cold boots are always there when the computer's been off for a while.
The BSOD's I've encountered:
Bad_Pool_Header
Memory_Management
Page_Fault_In_Nonpaged_Area
I find it very odd that I can repeat the computer shutting off every single time at the moment by increasing the size of the window I'm playing a video in. INSTANT shut down.
Those BSODs all point to memory faults, but that can be caused by the PSU aswell right?
I'm about to order a new PSU, especially if people agree that that's probably it.
Other ideas are welcome...
Mainly I'm concerned that it might be a mobo fault, but I'm sure the symptons would be worse/different?
