I have a few issues but before describing them, here is what I have :
Mother board - Gigabyte 945GCM-S2L
RAM - 2GB DDR2 Single Channel
Processor - Intel Core 2 Duo E4600 @ 2.4gHz
Graphic Card - NVIDIA Geforce 7300SE/7200GS with 256MB
WLAN Card - NetGear WG311

That's it! ( not a high end computer I know)
P.S.- Not a computer genius
The issues are listed below one by one :
1)Sometimes when I start my computer, the monitor doesn't show as if it gets a signal and remains blank. Sometimes when it does start, the screen hangs at some place or the other, always random. What is causing the problem? Repairable? If not what do I need to do?

2) I am thinking of getting some more RAM. Please tell me which RAMs would be compatible? (2GB and 4GB ones)

3)Since my graphic card is too old (and might be the problem of [1], i would like to upgrade it. I am not really a hardcore gamer , so please suggest some graphic cards with 512MB-1GB ram compatible with my motherboard and in the range of 1500INR-3000INR (25$-50$) or maybe a bit more than that.

4) I usually open the cover of my CPU for better cooling but the dust gets it.
I would like to clean it, but am really not sure how to, since if I accidently get too rough, it might get "cleaned", not as I would intend.

Please answers to these queries would help me a lot. Also, if you are suggesting some component to buy or upgrade, links would be highly appreciated. Thanks a lot!
 
1, it can be anything from board down to psu, since im thinking that your rig is a bit old already.
2, i would not suggest getting more ram, because they are more expensive than ddr3 and you wont be able to use ddr2 if you upgrade in the future.

3, personally i would not go anything lower than a 7770

4, you can use a blower, just dont overdo it. personally i just clean it with a brush, a clean brush of course.

but, if i were you, ill just get a new rig. will last you longer and give you better performance than keep that and spend money while not getting much better performance.
