'Random' BSOD when using browser and/or gaming

Several weeks ago I noticed substantial computer slowing and pursued various options for virus scanning/removing beyond what I was already using (Panda). System came up clear.

Last week I had a BSOD when running Chrome + java based game client.

Today I have had 2 BSOD when using the Chrome and misc programs.

All 3 times the error displayed was: IRQL GT Zero at System Service

Currently using Win 7 in safemode + networking and PC seems to be doing fine--but it seemed to be doing fine prior to BSODs (besides the general slowing)

I have attached the DM files as requested in the guide--lemme know if there's anything else needed. I do tutoring work from my PC and I'm just glad I'm not booked tonight!

Based on a cursory examination of the event log, I would look into the (1) video card and (2) HDD.

1) Make sure the fan is fully functional, the heatsink is clean, and the temperatures remain within safe margins. If you've done any overclocking, disable it for the time being.
2) Run disk self-tests. Most manufacturers provide a utility specifically for their own drives. Seagate's utility will allow basic testing of other brands, and there are also generic utilities. Then run chkdsk to ensure the filesystem is in good order.

Hey there thanks for the response.

Video card fan did some faint twitching (not spinning) when I had the system open a day or two ago--but after researching the topic found that with the temp it was registering at it was normal to have the fan not on. Of course, twitching probably isn't normal--but with a fine temp does that exclude the fan as an issue? Card is new as of Feb 2016

Have run several of the Seagate checks, so far fine. About to run chkdsk and will update then.

Went through the woods on this for misc. reasons but eventually got a full chkdsk run and it did indeed find some issues but I am unaware if this is what caused the problem...Have bolded the things I noticed.

Unfortunately, I can't offer any better suggestion than to wait and see if the problem persists.
