"upgraded" Dell Precision T3400
OS: Windows 7 64-bit Professional
CPU:Core 2 Duo E8500 3.16 GHz
GPU: AMD Radeon 7790
HDD:160 GB Maxtor, 320 GB WD, 2TB Seagate (main)
RAM: 800 MHz Dual Channel 4x1 GB ECC
BIOS:Phoenix Rom BIOS Plus Version v1.10 A14
Sorry for poor formatting (no PC atm to use) and lack of full system info(dxdiag/speccy etc)
-Flickering Display Constantly (losing and regaining signal from GPU)
Also occurs in BIOS Screen
-Blank Screen/No signal from GPU after logging in (immediately or 5-30 seconds after Desktop appears)
- Cannot wake up from sleep mode 70% of the time with. Mouse or KB (even with Ctrl Alt Del or Win+D)
Results in a black screen but still signal (unresolved)
-Edit: After some research this issue may be caused by Dell's motherboard by the hybrid sleep option in their workstations
-Cleaning the GPU
-Reseated GPU x 4
-Switched between HDMI and "DVI to VGA" outputs (TV with HDMI, monitor with DVI-to-VGA)
-Safe Mode (no black screen after login but still flickering display)
-System Restore (undid DirectX Install)
-Artifacting/Distorted colors in several of my reboot attempts- "fixed with driver reinstall"
Afaik there was no windows update or the sort
Could this be hardware or software issue? For one of my reboot attempts I was able to login and use it for around 4 minutes before it froze (the image of the monitor) and lost signal. I appreciate any help!
Edit1: Rebooted again (40th time) after reseating and cleaning motherboard and PCI slots, logged in, and the my screen started flashing random colors (similar to a stuck pixel test), my main concern is everything looks normal without artifacts or color distortions (with the exception of the constant flickering) until after logging in which either produces a black screen or flashing colors and then signal loss.
Edit2:Issue persists even when loading up back up copy Windows 7 (4 months old) from my other drive
Edit3:GPU does not appear to be overheating or has an history of overheating
