Dell PC (i5) freezes after hours of being idle
Hello!
I have gone through several topics on forums and could not find the response to the problem.
I bought a new Dell Optiplex 9020 (i5) 2 months ago. It came with 4GB RAM (2x2) and 500 GB HDD.
I loaded it with another extra 500 GB HDD, removed the old 4GB RAM and added 8GB (4x4) and added a graphics card Radeon HD 7970 1GB DDR 5. Windows 7 genuine Ultimate.
The system freezes on some days when I leave it on throughout the night. I disabled all the power settings and made it as "always on" and never to turn off the display. The system just freezes without any response at all, showing the desktop or whatever page I left open. All I can do is hold down the power button to switch it off.
Could it be the GPU? Or the RAM? I also notice a significant slowdown when I install games. Other things like winamp or chrome don't work or are very slow during game installation running in background. This is something I never had a problem with in my old pc (which was running i3). However, the system brilliantly runs the latest games without any issues.
I am confused as to why this is happening. Is there anyone who knows what could be causing the freezes? and also what could be causing the PC slowdown while installation. It is newly formatted a week ago.

Could be a driver issue, malware, or hardware.
You did not add a 7970 card to a 9020. It won't physically fit into the case.
What do the event logs have to say?

BZZT Wrong Answer Again.
7790 Requires additional Power.

With all due respect, if you haven't tried it, don't comment about it. If you are a user, please dont behave like ur an expert or the admin. I am not here for malware removal and don't need reminding what forum im on.
The HD 7790 fits perfectly. Yes I didn't say it doesn't need power. Power is easy with SATA to PCIE adapter. You can see that in below pictures.

Sata to PCI-E connection does not make your power supply have sufficient Current to run the card. This is why Dells that DO support a 150W + card have an EPS12v 575W or larger power supply. The reason the supply does not have the connectors you need is because it's not large enough to properly power a HD7790 card.
You could add 450W

Agreeable argument. The dell pc sports a 290 Watts AC290AM-00. The reason I dipped in the 7790 was coz the retailer assembled i3 i used earlier was powered by a lower end 250 watts smps and still punched the HD 7790. An upgrade is in order and I I could add the booster (for which I have no space) or a larger power supply. But I believe not at the moment since that really doesnt solve the problem.
Coming back to why I posted this question. The Pc still gets the freeze, HD 7790 or not. Trying without the HD 7790 in the system and using the motherboard display also trips the freeze button.
Not malware. I formatted the system yesterday. Running an Eset and also haven't opened up any websites etc.
