Also I took out the RAM stick, plug back in and turn on, then when i turn it on with no RAM, the motherboard beeps continuously.

That's normal, no RAM gets you a BIOS error beep code as part of the POST. Power On Self Test. A single Beep means everything is OK. On a desktop PC anyway. My laptop doesn't Beep unless there is an error. My desktop PC gives the one beep every time I boot it up.

I think you've had either a GPU or CPU failure, maybe an overheat. Diagnosing and proving it is very hard. No BIOS on screen means its not finishing the POST. It's a hardware issue. It could even be a motherboard fault. No BIOS error Beep code doesn't help. My guess is its failing very early in the POST. Wish I could be more help. If it's the onboard graphics that have failed you may be able to put in a dedicated card and get it working again. No guaranties though. If you can borrow a compatible graphics card for your system it may be worth trying it. Otherwise, your likely looking at taking the PC somewhere to be repaired.

After tinkering with the CMOS for days, only to figure out that my upgraded memory became defected. I saved the original OEM ram stick. Bad news, it's half my upgraded ram (2gb) and my memory seems to hover at 90% usage after 15 minutes of uptime. :/

are you sure ?

Where are you getting that figure from ?

Post a snip.

You need at least 4 GB with Windows 7 and I recommend at least 8.

2 GB is not enough at all.

Return the defective memory.

Good tinkering. Get some new new RAM and you should be back in business.

8GB? With my processor, won't that be a bit overkill?

What does the CPU have to do with how much RAM you have and use? I run 8 gig in my laptop and desktop PC.

display/monitor 1024×768 display size
the display/monitor uses the generic driver for display and it is 1024×768 or 800x600 but it looks very odd it should be bigger because my screen is bigger. I have a acer monitor but is there something I can download to fix the display size?
