I am trying to get to the root of why my PC has started crashing after upgrading my GPU and PSU to a Radeon 7770 (Diamond) and Dynex 500w PSU. Game play is great, it's nice and smooth, I can max out the settings no lagging occurs. However even at lower graphic settings certain games will do one of three things,

1.Freeze for a couple seconds with sound continuing to play then it unfreezes and I'm able to play again.

2. Freeze then send me back to desktop with Display driver crash error/

3. Freeze and Blue screen of death with system restart.

My temp ranges on my GPU range from 55c to upwards of 77c

I have had advice kind of range from defective card to cheap PSU and was hoping with more detail someone could really narrow down a solution. Thank you for your time.


update: I did uninstall the previous drivers. I also updated my drivers/bios. Soon as I can find a deal on a new Corsair I'll pick one up, but most advice I get is that the PSU should be fine since the radeon 7770 uses very little power.


update : I wanted to add this also its the MSI afterburner results I have no idea how to read this properly maybe there is something in there that can help determine what is causing the crashes

Prior to replacing the stock HD 7450 with the HD 7770, did you un-install all the drivers that HP had on your system. If not un-install the current package and install the 13.9 CCC package.

I have almost the same specs, and the same problems.

Windows: Microsoft Windows 7 home premium 64-bit (6.1.7601)

Memory: 10240 MB

PSU: 650W corsair

CPU speed: 3.3GHz

CPU info: AMD FX(tm)-6100 six-core Processor

I have 2 monitors same 1920x1080 resulotion

Manufacturer is Hewlett-packard

system model: h8-1214

Motherboard: Can't find it, but it's probably eerily similar


I cannot update my drivers.  No matter what I download, no matter how many times I uninstall my drivers and reinstall them regardless the program I install, my drivers ALWAYS end up being V12.104.

Even though I know i need V13.9.

A friend of mine downloaded V13.9 himself, then sent the packett to me, after using this, my drivers updated to 13. 152 And won't update any further.

13.152 has the same issues 12.104 did.  Shortly I'm going to return this product, because I've contacted support 3 times for this issue alone, and a couple other times for other issues I had too.  This card is barely seeming like it was worth the money. 

WTF HD 7770 double black
