HD6450 keeps causing my system to crash please help

[Jason_61]

I bought this AMD Radeon HD 6450 made by XFX, I installed it around a year ago and ever since have had problems. Their are a lot of time it just crashes on me sometimes the screen will recover where as other times the PC itself restarts. what Initially happens before the crash is i will get blue or yellow checkered squares that pop up in vertical lines on the screen. then a pop up saying "your display driver has stopped responding and has recovered. Ive changed the TDRdelay but still no change in any thing. This link >> http://support.hp.com/us-en/document/c02871948 is the specifications to my computer besides the upgraded GPU. any insight would be great. ive updated countless drivers. factory reset the whole computer and even ran benchmarks trying to find a solution.

sometime them hp proprietary motherboards may have a restricted PCI-E slot like limited to just 25w and that card need full 75w at the pci-e slot to work properly ?

maybe the proprietary HP bios don't fully support that card ??

I do see at hp forums on that model the hd 6770 is being recommended ???

maybe look in to that PSU issue they refer to maybe too light duty and not putting out enough for the card . also could be you just got a lemon card ? we all got one in our lives from time to time

sounds more like starving for amps . its a wonder it lasted this long then ,and running it like that the damage may of been done ??

Mainly I have been using MSI afterburner to raise the core clock and memory clock up by quite a bit. it helps with the crashing, sorta prolongs it. but if it is my PSU how would I go about returning to my Factory GPU built into the mother board. every time I take this graphics card out and restart I get no visual on the screen to where i can download the original drivers for said Factory GPU on my motherboard

check you boards manual and see in the bios settings if the onboard graphics have been disabled - some HP don't auto detect that ?
