BSOD before and after OS reinstall, DRIVER_IRQL_NOT_LESS_OR_EQUAL
Hey, hum, you must have a ton of these already...
Short story: Sudden freezing and Kernel error one night after clearing dust and testing system limits, next morning had difficulty accessing/deleting one particular image file that crashed Safe Mode every time I tried copying/deleting it (wanted to backup a few folders for work), saved all except that problem file and reinstalled OS. Ran chkdsk twice and on pass 5 both times, crashed at ~74% with DRIVER_IRQL_NOT_LESS_OR_EQUAL. System currently stable but I haven't installed my old stuff yet, too anxious.
Long story and details:
I've had this computer for quite some time -perhaps 5 years?- without hiccups, but on July 11th at ~midnight I got hit with a BSOD about a kernel error. A bit of back story: I haven't dusted my computer since I got it, which is a terrible shame I know, and I've had it freeze on me occasionally since April this year. So on July 9th I carefully removed a huge dust bunny in my fan which made my cpu temp at least 20-30c lower even when super busy (it peak at 60c now instead of 80c...). I started checking temps recently but didn't think of dusting the innards, I'm so lame. I wanted to test and see if my computer would freeze on me again so I had Minecraft loaded for some time and a graphics heavy Firefox page (I could have opened anything but I just wanted to play MC, also I had the Java programs run with only 2 cores instead of all four of them). It was doing fine until the 10th in the afternoon or evening when it crashed. I had to force shut down/restart and when I wanted to update my backups, it gave me the kernel BSOD at midnight.
The next morning, I tried booting up again but I kept getting the BSODs so I went on Safe Mode. Very stable until I tried copying one particular folder with image files and it tells me it can't copy it because the folder doesn't exist or it's in a different destination. I opened the folder and all jpgs had their thumbnail showing except for one which crashed my system every time I tried deleting it. I believe it could have been a gif if that information helps. So I saved all the new stuff except that one file, tried chkdsk and system restore and most Windows recovery whathaveyous before I blew a fuse and wiped everything. I needed a major cleanup anyway.
So now it's all new and sparkly but after installing all the updates and running chkdsk twice it now gives me this error: DRIVER_IRQL_NOT_LESS_OR_EQUAL. So far it's stable but I haven't installed anything I used to have so I can't really say for sure. Attached are the DM logs required, but I have no information of the sort prior to reinstalling my OS.
Oh before I forget. When I tried System Restore, it gave me July 8th as a date (the only point/date available actually) which I beliiiieeeeve must have been a important Windows update but I can't remember. The freezing were not new, the BSODs came after the 8th so... coincidence?
What I have is a store-bought computer: Acer Aspire M3400, Win7 64bit, AMD Athlon II X4 635 Processor - 2.90 GHz, graph card ATI Radeon HD 4250.
